Chipboard production equipment. How chipboard is made: equipment and manufacturing technology

Among the practical and multifunctional wood materials, a special place is occupied by chipboard or simply chipboard. Their manufacture can take place both at large wood processing plants and at home.

purpose

Chipboard is an environmentally friendly, easy to process, functional material, and a high-tech alternative to solid wood. It is used to sheathe walls, roofs, make wall panels, create flooring for carpet or linoleum, floor, various partitions, make a wide variety of furniture, packaging, build enclosing arrays, decor interior spaces. What is the production technology of chipboard? How is it made at home? We will consider these issues later in the article.

What is chipboard made of?

The basis of particle board production is a process in which sawdust is mixed with a special adhesive mass and the resulting mixture is pressed under high pressure and high temperature. A big advantage of the manufacture of chipboard is the use of sawmill waste.

Pressed boards have good strength, created by mixing the sawdust mixture with glue (resin) hardened to the state of stone. For the production of environmentally friendly types of material, an adhesive mass of minimal toxicity is used.

The manufacture of chipboard can take place on a small scale of production. In general, only the size of the boards produced is limited, which should be no more than 50 x 50 centimeters.

The production of chipboard at home is the same process as in the industrial scale, but in miniature. All stages where automation should be involved are replaced handmade.

How to make chipboard at home

Consider the sequence of manufacturing chipboard:

  • first, the sawdust mass is mixed in a medium-sized container (from 10 to 15 l);
  • then an adhesive solution is added, it is necessary to ensure that the sawdust is completely saturated;
  • a tiled form is attached at high pressure;
  • then, with the help of high temperature, the workpieces are pressed, this process requires special equipment;
  • the manufactured plate is cooled in air, and its edges are cut off.

Surface lamination is carried out in the same baking press that is used in the production of untrimmed blanks. You can purchase a ready-made special laminate for chipboard, which can be “baked” to the surface in a certain way with an iron. Such coatings have a beneficial effect on appearance wood boards, but are not considered a full-fledged laminate layer.

Equipment

Before making chipboard, you need to prepare the equipment. The technology for creating this material is based on the use of elementary and practical equipment, which is connected into a common system. It is not necessary to use the most technologically advanced devices for the production of wood-based panels, but it is quite difficult to set up and maintain the working capacity of the entire production line.

Equipment list

The complete list of equipment for the production of chipboard includes:

  1. Mixers, which are needed in order to obtain a homogeneous mixture prepared from sawdust and adhesive (usually resin with special impurities to create a solid structure).
  2. Forming devices are needed to impart viscosity and shape to the mixture.
  3. High temperature pressing equipment and machine tools.
  4. Coolers are used to make hot chipboards cool faster.
  5. Edge cutters that remove edges from boards.
  6. Grinding machines make the formed surface smooth.

The operability of all equipment in large-scale production is ensured automatically. The quality of work is controlled while maintaining the settings of the mechanism at the desired level.

All of the wood-based panel manufacturing equipment listed above will be suitable for a job that requires ready-made raw materials.

If in the manufacture of chipboard the plans include the use of their own source material, then the equipment package must be supplemented with additional auxiliary equipment, such as cutting machines, chippers, mills and planers.

Among other things, additional equipment that will increase the manufacturability of the production of wood-based panels includes conveyors, tables equipped with lifting mechanisms, ventilation systems necessary to remove sanding dust, drying chambers and conveyors. Consider how chipboard is made.

Manufacturing technology

The composition of wood-based panels includes wood chips, which are formed as waste from the production of wood. During the standard cycle of work, the non-functional mass is converted into ready-to-use slabs.

Consider how do-it-yourself chipboard is made.

Manufacturing sequence

The manufacturing steps are as follows:

  • first you need to find raw materials, sawdust and wood chips in the warehouse;
  • then the raw material is prepared for work by grinding;
  • the materials are dried to obtain a suitable consistency for gluing;
  • wood chips are screened using automated sieves, sorted according to size;
  • larger and smaller chips are mixed with each other;
  • resin adhesive is added;
  • a mixture of viscous consistency is sent to a molding machine that forms wood boards;
  • Chipboard is pressed under high pressure and high temperature;
  • plates are cooled;
  • the edge is trimmed, and the resulting blanks are sawn into pieces of the required size.

So, we looked at how chipboard is made. Grinding this material is necessary as a final step in the manufacturing process. It is the level and quality of grinding that directly determines which grade the finished product will be assigned to. Chipboard of the first grade should not have scratches, spots, insufficient polishing, waves on the surface.

The required parameters of wood-based panels are controlled both during production and after the chipboard is ready. The manufactured sheets are stored in blocks, which are stacked on special wooden pallets - pallets.

Milling process

The creation of figured surfaces from the inside and the processing of corners from the outside is performed during the milling process. A cutter is a cutter equipped with teeth, it usually has any regular shape (for example, a cone or a trapezoid). Chipboards need to be machined all the way through the thickness, which is different from machining harder materials. This is necessary so that accidental chips do not appear.

Before you start milling, you need to prepare. To do this, you need to cut out the contours of the planned figures in advance using a jigsaw or saw. Processed usually by hand or with a stationary milling cutter. In this way, holes in the form of a cylinder and an oval of any size are obtained, which ensures the aesthetic appearance of the finished slab.

What is the process of laminating chipboard

Considering how chipboard is made, let's dwell in more detail on the lamination process. Any furniture, including cabinets, kitchen sets of any class, is made of wood-based panels, the surface of which has passed a special stage in processing, has been laminated with special materials necessary to protect the product, as well as to create a more aesthetic appearance. These products are called chipboard or expanded laminated chipboard.

To laminate the product, it is necessary to apply a stable coating to its surface, which improves the appearance, no additional processing is required.

The main stages of the process of laminating wood boards are as follows:

  1. First, the highest quality material is selected for the most durable and dense products, which have little moisture.
  2. Chipboard is coated with a primer to ensure the best adhesion of the laminate;
  3. Now several layers of paper are applied (no more than three), which are impregnated with a mixture of resin. With the help of paper, the product will be more durable, and the coloring of the outer part creates an aesthetically attractive appearance of the plate. The process of creating layers accompanies pressing at high temperature.
  4. Further, the product is quickly cooled, sometimes by watering.

The surface of the particle board must be carefully polished before it is laminated. If even small roughness and uneven places remain, this can lead to damage to the laminate layer and, accordingly, the product will be rejected. Do-it-yourself lamination process at home is very difficult to produce high-quality, therefore, already processed chipboard made in industrial conditions is often purchased for subsequent use.

Laminated chipboard (LDSP) is the main component for the production of cabinet furniture, which authentically imitates natural wood, but much cheaper.

Cheapness due to the use woodworking waste- shavings.

The production of laminated chipboard has several basic technologies.

  • what is chipboard;
  • how the production of chipboard differs from the production of chipboard;
  • what documents regulate the quality of chipboard in Russia;
  • what equipment is used for lamination;
  • How is edging tape made?
  • how to laminate chipboard yourself.

chipboard is ordinary wood chipboard that we talked about lined with a decorative coating.

The coating can be either one-color and smooth, or multi-colored or imitating the texture of wood.

Key features such as:

  • bending strength;
  • ability to hold a screw;
  • density;
  • moisture resistance classes;
  • formaldehyde emission class;
  • flammability

fully correspond to the same characteristics of the source material.

The thickness of the laminated material depends on its purpose. For the manufacture of cabinet furniture, most often take chipboard with a thickness 16 mm, however, table tops are often made from slabs thick 25–38 mm.

Chipboard for wall, floor and ceiling cladding is made of chipboard with a thickness of 8–12 mm.

A laminating layer with a three-dimensional pattern increases the thickness of the chipboard, because such the pattern is created by pressing the base layer, pushing the contours of the pattern on it.

Outdoor the film only follows the contours this drawing.

How is chipboard made?

For the manufacture of laminated chipboard, ordinary polished chipboards are used, so they are produced at a chipboard plant, by connecting the lamination area.

Moreover, 3 technologies are used to cover the source material with a laminating film:

  • lamination;
  • laminating;
  • smooth lamination.


lamination

When laminating 1-2 layers of specially prepared paper are glued onto the base, and the first layer - the base - is made as thick as possible so that the pattern can be pushed through it.

The thickness of the base, depending on the depth of the pattern, can reach 0.5–1 mm, the thickness of the second layer is tenths or even hundredths of a mm.

On top of these layers, another one is laid, made of transparent paper and a mixture of various resins, which when heated, they turn into a strong film, reliably protecting the decorative surface.

The main layer is laid on the prepared chipboard surface and pressed down with a hot stamp with a suitable pattern.

The surface temperature of the stamp is 150–220 degrees, due to which the resin impregnating the main layer is mixed with the resin that glues the chips in the chipboard and, paper becomes an inseparable part of the plate.

Then, in the same way, a decorative layer with a suitable pattern and an outer layer protecting the board from damage are glued.

At some enterprises, all layers of the coating are first connected to each other, then dried and, only after that, they are attached to the chipboard.

With this technology, the coating is made in the form of a tape. A pattern is formed on it using a cylinder with an installed matrix, similar to the formation of a pattern during laminating.

Difference with caching in that the tape is fastened without glue, heating the resins impregnating the paper until melted and mixed with the resin in the chipboard.

Laminating

When laminating, the facing material is first prepared, for which all layers are laid in order and a pattern is printed on them. using a cold press.

At the same time, the uncured resin of the various layers is mixed, due to which the coating turns into a wide and long tape.

If a drawing is used to print cylindrical die, then it becomes possible to ribbons of any length.

Many small businesses producing 3D textured laminate prefer do not spend money on expensive equipment necessary for the manufacture of the tape, and buy ready-made material.

The finished tape is sent to the dryer, then wound into rolls, which are delivered to the laminating area. There, the facing material is cut to size and laid on a plate lubricated with special glue, then pressed down with a press and heated until the glue is completely polymerized.

Thanks to this technology veneer goes faster, after all no need to heat each layer of coating separately so the company can produce more products.

The disadvantage of this technology is that the glued lining holding on much weaker than real lamination.

Smooth lamination

This technology similar to caching, however, it is a full-fledged lamination, because when heated, the resin of the coating and the plates are mixed, forming single material. In addition, in the strip preparation area no press to create a pattern.

To create a smooth surface, it is enough to lay 2 layers, the lower of which will be made from paper, and the top one is made of a special film, which, when heated, forms durable and transparent coating.

Thanks to major manufacturers Chipboards are constantly looking for ways to increase the manufacturability of production and reduce costs, various changes are constantly being made to this process, the essence of which manufacturers keep secret. After all, any improvement in the quality of the laminating coating, as well as cost reduction, makes their products more competitive.

Documents regulating quality

The main document regulating the quality and characteristics of chipboard in Russia is GOST R 52078-2003, which you can find at this link.

There is also international standard EN 14322:2004, which is in many ways similar to the Russian one. You can find him.

These standards differ from those adopted for chipboard only by the requirements for the laminating coating. In everything else they completely identical.

Besides, there are various specifications (specifications), which are developed by both manufacturers of laminated chipboard and furniture manufacturers. Specifications prescribe those requirements that are not included in generally accepted standards or, for some reason, are knocked out of them.

For example, in TU can be prescribed non-standard product sizes, and also indicated detailed composition of the adhesive, which differs from what the company uses in the production of conventional chipboard.

Equipment: plant and its components

In most cases, for laminating chipboard, a multifunctional device is used, which is called laminator. Its basis is powerful press with steam or oil heating of the plate, as well as with the possibility of installing matrices with the required pattern.

The laminator can be large, capable of handling maximum sheet sizes, as well as medium or small. If a large press is installed, then after cooling, the laminated sheet enters the cutting machine, which is completely similar to that used in the production of chipboard.

In addition, the laminator can be one or two sided, that is, stick the film only on the front side or simultaneously process the front and back planes.

Medium-sized presses are designed for laminating already cut boards, the size of which complies with the requirements of GOST R 52078-2003 and EN 14322:2004.

The small press is designed for laminating finished parts, such as input and interior doors or furniture items. Therefore, the enterprise you should choose a laminator based on the range products.

In addition, along with a large or medium laminator, a tape laying line is often used, which also performs several functions:

  • determines the quality of preparation of the chipboard surface for further processing;
  • lays the tape on the slab and orients it correctly;
  • cut off excess tape.

In factories where small laminators are installed, this operation is usually performed by a specially trained highly qualified worker stacking and cutting the tape by hand. Most often, this is done in furniture factories, when they have to make parts that, for some reason, cannot be cut from a whole sheet.

Similarly, they act in large woodworking workshops or industries that manufacture not only furniture, but also various carpentry products.

The laminator can be used not only for lamination, but also for general gluing, so it makes no sense to spend money on a special line.

Often, after cooling, medium and small slabs are fed to a sawing machine, which cuts 1–2 mm of the slab, forming a smooth edge. Such a machine is equipped circular saws large diameter tungsten carbide or diamond coated.

They move the plates along the entire line using belt conveyors and vacuum lifters, and all operations are automatic.

The cost of the equipment depends on many factors, so most of the enterprises that produce such lines and individual machines voice the price only after the customer provides specific requirements for configuration and performance.

On Aliexpress and other sites you can find individual devices and entire lines indicating approximate cost excluding delivery and installation.

Medium single-sided laminator for 1220*2440 mm boards can be purchased for 100-200 thousand US dollars, and a 60-120 cm wide laminating tape supply line will cost 18–25 thousand US dollars.

Edge tape

In the manufacture of laminated chipboard, only the front and back surfaces are laminated, and edges remain uncoated. Therefore, enterprises producing laminated chipboard, along with it, also supply edging tape, which is used for self-laminating the ends.

The color of the tape is fully consistent with the color of the plate, so after sticking the tape, the entire plate becomes one-color.

The tape for edging, that is, pasting the edges, is made noticeably thinner than the one used when facing particle boards in production. Indeed, in the conditions of a furniture workshop it is impossible to create such a high pressure and most craftsmen manage with an ordinary iron, warming up the tape laid on the edge.

How to laminate chipboard yourself?

Not always Chipboard, which can be purchased in stores, matches the color or pattern, so you can veneer the plate yourself.

For this, various types of decorative films that are sold in hardware stores are well suited.

Films are self-adhesive and conventional.

To apply a self-adhesive film, a thin protective coating is removed from it and placed on a chipboard sheet cleaned of dirt and dust, then rolled with a roller, removing air bubbles.

To apply a regular film, use a special adhesive recommended by the film manufacturer, then wait 2-5 minutes and carefully apply the film, do not allowing wrinkles to appear.

Such methods allow you to stick on chipboard only those drawings that are in the store, so you can use the method that was used in the days of the USSR when chipboard was in huge short supply.

A thin layer of primer (PVA diluted with water in a ratio of 5:1) was applied to the chipboard surface cleaned from dust and dirt. Then, the desired drawing was made on sheets of landscape paper and PVA was primed on the reverse side.

After 2-4 days, when the glue had completely hardened, the sheets with the pattern were laid out on the surface of the chipboard in such a way as to bring the pattern together. Then each sheet was heated with an iron.

If all the sheets were correctly laid and heated, then after cooling they formed a continuous pattern that completely covered the entire surface of the plate.

However the shift of any of the sheets led to a violation of the pattern and spoiled the whole picture, therefore, for greater reliability, they tried to get not landscape, but printing paper, which exceeded the plate in size.

The finished drawing was covered with furniture or parquet varnish in 2-3 layers and a home-made laminate was obtained. with low coating strength, but with the necessary pattern.

Conclusion

The production of laminated chipboard is a complex process that includes many operations, therefore, in order to turn ordinary particle boards into laminated ones, it is necessary site with good facilities.

After reading the article, you learned how the lamination process takes place and whether you can do it yourself.

In contact with

As you know, chipboard (chipboard) is widely used for the production of various structures. This material is inexpensive, durable enough, practical.

However, when it comes to use in a residential building, many people have a question: what materials are used to make such plates? And this is understandable: environmental friendliness and safety are an important point.

Now we will answer this question.

What is chipboard made from?

In fact, the manufacturing technology is quite simple. And few materials are used. Namely:

  • shavings, sawdust;
  • binder;
  • special additives.

Now let's take a closer look at what chipboard is made of.

sawdust, shavings

Sawdust is the main material used to make chipboard. Often this is a waste of woodworking, sawmilling enterprises.

Chips and chips can also be used, which are loaded into special crushers before making chipboard, where they are ground into small pieces. In fact, the same sawdust is obtained.

Particle sizes may vary. But basically their thickness does not exceed 1 mm. Of these, the largest go to the formation of the inner layer of the plate. And small particles form its upper layer (due to this, a relatively smooth surface is obtained).

Typically, such raw materials for the production of chipboard are obtained from low-value wood species (coniferous and hardwood).

Binder

In fact, it is a glue, due to which the particles bind (stick together) to each other, forming a solid body. Synthetic resin acts as such an adhesive. Often, glue is obtained by mixing resin, paraffin, chemical hardeners and water.

By the way, you have probably heard that chipboard emits such a harmful substance as formaldehyde. It really is. And… have you guessed where it comes from? Yes, that's right - it is binder resins that emit formaldehyde. These are substances of non-mineral origin.

We can say that the release of formaldehyde is the main disadvantage of chipboard. After all, everyone knows that this substance has Negative influence on people's health.

Another thing is how much formaldehyde is contained in chipboard of various manufacturers. This is another question.

Special additives

Not always used. Their purpose is to add special properties to the plates. As a rule, the volume of such additives is approximately 6...10% by weight of wood particles.

Additives can be used that give chipboard fire resistance, moisture resistance, additional strength (flame retardants, water repellents, antiseptics).

Materials for chipboard cladding

Boards intended for the manufacture of furniture and other products can be veneered. Surely you have seen such chipboards many times. Looks very attractive, available the most various colors, shades, textures.

The plastic used for facing chipboard gives the boards good moisture resistance. Yes, and the appearance is very attractive. Often such plates are used for the manufacture of kitchen furniture.

In addition, as facing materials paper, polymer films of various colors and shades can be used. By the way, resins, varnishes and other substances are used to strengthen paper.

In pursuit of super-profitable and often overly technologically complex industries, novice businessmen often simply do not pay attention to the most simple materials, which different reasons seem to them outdated, unused and unattractive for investment.

Such materials include, for example, chipboard, or chipboard. Many people generally consider this material to be just an attempt to recycle woodworking waste and are surprised to learn that special chippers and chippers are often used in chipboard factories to produce so-called non-commercial wood from non-commercial wood. technological chips - i.e. the main component of chipboard.

But chipboard is used very widely: furniture manufacturers use laminated board in the manufacture of doors, sides, facades, and polished board - for various hidden elements; builders and finishers also widely use wood board - mainly to create various floorings; in addition, manufacturers of trucks and wagons make partitions and bulkheads from chipboard. Although, of course, the main consumer of this material is furniture production.

But why not produce some more technologically advanced material - the same laminated chipboard or even blanks for modular furniture? The answer is simple - the production of the starting material is much cheaper and technologically (and hence in terms of investment) low-cost. The production of chipboard requires much less equipment, and the cost of materials, than the manufacture of its derivatives - for example, laminated chipboard.

It is obvious that starting a chipboard production can turn out to be a very profitable business, especially if there is access to cheap raw materials - sawmill waste. The sales market is practically unlimited, so there will be no problems with this.

Technology and equipment for chipboard production

Chipboard is obtained by hot pressing a mixture of chips and thermosetting resin. In general terms, the technology is as follows - the chips are mixed with a binder, and placed in molds, where they are under the influence of high pressure and temperature is glued together. Then finished slab removed, cooled, cut and polished.

The chipboard production process itself can be divided into several stages: preparation of raw materials, obtaining chips, mixing chips with glue, forming a carpet, pressing and gluing boards, cooling and trimming edges, grinding ends and faces.

By and large, the first two stages are optional if you use imported material. If not, then you will have to purchase a crusher or chipper (160-460 thousand rubles, depending on the type, power, etc. characteristics), as well as a chipper (approximately 1280 thousand rubles).

As you can see, some additional costs, although small, will still be required, so it makes sense to think about the advisability of working on finished or requiring preparation of raw materials.

However, this question, due to its financial miserliness, is rather resolved when studying suppliers: are there any relevant manufacturers of technological chips in your city.

Chips are mixed with glue in special mixers (235 thousand yuan per unit), where chips and heated resin with hardeners and other additives are fed. At the same time, it must be remembered that the weight fractions of chips and resin are strictly regulated, and from a violation of their ratio in any direction, a deterioration in the physical and mechanical properties of the product may occur.

The formation of the carpet is carried out with the help of forming machines; they place the resinous shavings into the mold. Pressing and gluing chipboards is carried out in special thermal presses. The total price of the twin forming machine and 8-layer press is only 1,536,000 yuan per set. After the blank sheet is produced, it is cut to the specified dimensions using an automatic sheet cutting machine (88,000 yuan per unit) and fed to polishing.

Chipboard grinding is the final stage of machining in the production process, and the grade depends on the quality of surface grinding: according to GOST 10632-89, first-grade boards should not have recesses (protrusions) or scratches, paraffin, dust-tar or resin stains, chipped edges, chipped corners , under-grinding, surface waviness.

Slabs of the second grade may not be polished at all, but they are used only in construction - for furniture production it is sanded boards that are required, although often chipboard manufacturers purchase second-grade boards and grind them themselves.

Used for sanding chipboard sheets grinding machines, the selection of which takes into account such parameters as the working width, the number of grinding heads (usually 2, 4 or 6 grinding heads) and power. According to these parameters, there is a spread in prices - from 440 to 995 thousand rubles.

The above equipment for the production of chipboard is the main one. Additional include vibrating screens; different kind roller, belt, spiral and chain conveyors connecting different aggregates; roller lifting table for laying finished chipboard sheets in packs; ventilation system for removing dust during grinding and some other specific devices (loaders; stackers, etc.).

As you can see, the list of equipment for chipboard production is quite small. However, in addition to equipment, production facilities are also required.

To deploy a full-fledged chipboard production, about 1800 square meters are required. m of the actual production area plus at least 600 sq. m of warehouse space - and this is not counting utility rooms, offices, sanitary and others.

Business prospects for the production of chipboard

Prospects for the production of chipboard are determined by the very specifics of this production. As you may have noticed, sanding, coating and other forms of finishing greatly increase the selling price of boards.

Ideally, first-class slabs are better not to be sold at all, but to be laminated or veneered on their own. This, of course, will require small costs, however, the sale of such plates occurs at prices much more expensive than usual.

In addition, on the basis of the production of chipboard, it is also possible to organize the production of related materials: MDF, fiberboard, etc., not to mention furniture production.

The production of furniture products is a very profitable business, which ranks second after the construction industry. However, this segment is this moment is very busy, so it will take a lot of strength for a beginner to enter the market efficiently.

If the question arises of how to start a business, it is worth saying that many entrepreneurs refuse to believe that it is much more profitable to produce raw materials for the furniture industry than finished products. At the moment, laminated chipboard (LDSP) is a very popular material that is actively used not only for the manufacture of furniture, but also for various interior finishing works.

Of course, chipboard is inferior to wood in a number of parameters, but ease of processing and low cost are its main advantages, so this material is in increasing demand every year.

If you decide to organize the production of laminated chipboard, you should be aware of another advantage of such a solution: at the moment you will have a small number of competitors in the market. The result of this can be called the drawing of a large sales market, since almost all furniture factories are ready to purchase materials for the production of their products.

Chipboard production is a competent business organization

Even a child understands that specialized equipment is required to make something. In this case, it is also needed. The production of laminated chipboard cannot be organized without the following tools:

  • Special dryer. It is used to make laminated paper.
  • Press. With its help, chipboard is pressed with such paper.
  • Calibrating and grinding machine (it affects the quality of the resulting surface).

So, not only the main equipment for chipboard lamination is necessary, but also the accompanying one. First of all, we can talk about a device designed to prepare an adhesive base, which is then poured into molds and pressed into slabs.

Chipboard base

Chipboard, or chipboard, is a fairly popular construction material, as well as the basis of chipboard used for furniture production. Chipboard is actively used in the following areas:

  • in the construction of floor coverings;
  • in the process of constructing various wall panels;
  • for the production of furniture, as already indicated;
  • as roofing material.

Such production can be called processing, since the main raw material for the manufacture of such boards is waste from wood enterprises.

Production methods

Chipboard can be produced in one of two ways - batch and continuous. The periodic method involves the use of storey processes of periodic pressure, and the continuous method involves the use of extrusion processes.

Features of the manufacture of chipboard

The production process in this case can be divided into a number of main stages:

  • Preparatory. At this stage, the preparation of raw materials is carried out by crushing wood to obtain chips of the required size. If you immediately purchase ready-made raw materials, then this step can be skipped.
  • The second stage involves mixing the chips with a binder, which is traditionally used as glue. It is very important to adhere to strict proportions, since with an excess of glue, you can get a product that has deteriorated technical properties, in connection with which such plates will be considered defective.
  • Next, the prepared mixture is placed in special molds, which are then pressed. The influence of factors such as pressure and sufficient heat, allow the material to seize to form a single whole.
  • Next, the resulting blanks are placed in a special chamber for drying.
  • After that comes the stage of trimming the edges of the plates.
  • The final step is sanding the slab.

You can organize production in a warehouse, where you can install not only a chipboard production line, and subsequently laminated chipboard, but also stands where finished products will be stored.

Necessary equipment

If we consider the production option, when all operations are carried out at your enterprise, starting with the procurement of the raw materials themselves, then a number of instruments and machines will be required.

The preparation of raw materials implies the presence of such devices:

  1. equipment processing logs into chips;
  2. drying chambers for chips;
  3. planer;
  4. vibrating sieve.

The material production process involves the following equipment:

  1. apparatus for mixing chips and binder;
  2. forms where the plates will be harvested;
  3. thermopress;
  4. dryer or cooler for products ready for further processing.

To implement the final stage, you will need:

  • sawing machine, with which you will give the sheet some specific dimensions;
  • a machine that grinds the ends;
  • devices for coarse and fine grinding.

The manufacture of laminated chipboard will require the involvement of a press in the process, which applies two-sided lamination. You may need transport devices, such as belt or roller.

About lamination

Initially, the production and lamination of chipboard boards was a very labor-intensive process that required enormous energy costs. Nearly 30 years ago, completely new types of resins were developed, with the help of which it was possible to start using new processes for laminating boards.

During production, it is very important to distribute the load as evenly as possible, which can significantly improve the quality of the plate. A product made in this way can withstand a large number of deformations and loads, which is very important.

Options for how to properly laminate paper have been developed for many years, but now a solution has been found, and it is very effective. The paper is made in impregnating machines, where it is treated with resin, which makes it possible to obtain a decorative film from it, which becomes plastic-like under pressure.
