Thanks to this technique, a dynamic effect is created, which allows you to visually enlarge the space of the room. The easiest way is to order such a facade in the furniture industry, where for a certain fee you will be made a model according to your requirements and parameters. But this is the easiest option. Despite the fact that all this seems complicated, you can make such furniture yourself, without the help of specialists. It is this article that will help you understand how to make a curved facade yourself.

The use of curved facades is often found in kitchen sets, prefabricated furniture structures or to make radius cabinet. This is done in order to give a beautiful and stylish look to your furniture, and most importantly, to maximize the use of all the space in the room. Another plus is that sharp corners will not cause damage to both the hostess and children, who often run around such pieces of furniture.

But in order to do this work yourself, you should consider some points:

1. To calculate such modules, a more complex design is needed than for conventional furniture.
2. For the manufacture of a curved facade, it will take much more money than standard.
3. It is difficult to find a profile curvilinear cornice and false panels, moreover, their price will be much higher than that of their counterparts.

But do not despair, because all this is not scary. If it's hard for you to do right project, calculate all the necessary parameters, you can ask for help from a company that manufactures furniture. They can provide not only calculation and software design, but also a three-dimensional model that will be made according to your sketch.

You can buy the necessary elements and accessories from the catalogs of manufacturers. You can get it at any specialized store, get contact information there. total cost furniture will be higher, but the quality is still guaranteed. At the same time, such furniture will serve you for a very long time.

Where to start

To make a do-it-yourself curved facade for a shelf, cabinet or kitchen, it’s good suitable stove MDF. If someone has already dealt with her, it will be much easier for him. It is soft and supple, so it can be easily processed. To make a curved facade, two plates are needed - internal and external. In total, the thickness of the workpiece should be 16 mm. To get radial parts you need:

• make an end template with the desired radius;
• subtract right amount plates to be curved;
• to cut blanks for bent parts;
• make markings for the cuts where the area will bend.

To make a curved facade, prepare the following tools and materials:

• MDF boards, at least 2;
• pencil, ruler and tape measure;
• circular and hand saw;
• wood glue;
• tassel;
• small nails and a hammer;
• small spatula;
• clamps;
• screwdriver and finishing tools.

Having collected such an arsenal, you can get to work.

We make a curved facade

So, to make a curved facade, you will need two sheets of MDF, the thickness of which is 9 mm. As already mentioned, one of them will be external, and the other - internal. From all sides the facade will be smooth. Since most of the furniture is made of wood. , there shouldn't be any difficulty at work. You will need a minimum of tools and a little patience.

To bend a slab to the desired radius and force it to stay in that position long time, simple effort is not enough. For this purpose, cuts must be made on the sheet, passing across the fold. First, make a template. It can be a shelf, cabinet or something else. We will focus on it, making the curved facade itself.

You need to cut MDF sheets with a margin so as not to be mistaken. After all, the excess is then easily cut off, and it will not work to finish the missing centimeters.

Remember that the inner radius of the curved facade is smaller than the outer one, so make the outer blank longer. Then you need to find the center of the two blanks and mark it with dashed lines in height from one side and the other. Based on these lines, further the workpieces will be glued together.

Depending on the type of bend, you need to mark the cuts, which allow you to make a rounded workpiece from a straight MDF sheet. Apply lines with an indent of one from the other 5 mm. It is thanks to these cuts that our design will be able to acquire a bent shape and not break. Now you need to make cuts. For this you will need a circular saw. Set it up so that you don't cut the sheet to the ground, but don't leave too much of a cut. The ideal is considered to be undershot in 1 mm.

In order not to spoil the finished workpiece, immediately before making cuts, use unnecessary trimmings for practice. Do it right: mark with a distance of 5 mm and start cutting. Remember, such cuts must be made both on the outer workpiece and on the inner one.

How many cuts to make depends on how much you need to bend the part. If you need to make a curved corner, you need several strips in that place. And when you need to make shelves for a sink or cabinet in the kitchen, where the bend radius is large, the cuts should be almost over the entire plane. Do not throw away sawdust from working with a saw, you will need it in your work.

After the cuts are made, they must be filled with a special paste, which requires wood glue and sawdust. You need to cover the slots on both blanks. The consistency of the paste should be such that it easily fills incisions, but not too runny. Using a spatula, rub the mixture into the slots. To avoid air pockets, apply the paste along the incision from the center outwards.

After that, dilute the glue using some water. With a brush, go over the two blanks with a solution to smooth out the paste and remove excess sawdust. Then install the inner blank on the template. An outer workpiece is laid on top of it, being combined with the applied dashed lines that were applied in the center of the workpieces.

Next, you need to nail the blanks to one another using thin nails. Don't hammer them too hard so they can be easily removed. Do not worry that holes will remain from them, everything exactly further on the facade will need to be primed, puttied and painted. Therefore, all holes will be hidden and invisible.

The facade must be fixed with clamps and left until it is completely dry. After drying, the workpiece must be cut as necessary, cleaned, sanded the edges and provided with amplifiers for fittings. After that, it is ready for finishing.

Making a curved facade is not exactly easy and fast, but such an element in your design will attract others, delight you with its beauty and save space. Especially if it's a small kitchen or bathroom. You will also protect yourself and your family from injuries and bruises.

Currently, curved MDF facades for kitchens, bedrooms and other furniture items have become increasingly popular. Rounded shapes allow you to get new design solutions and create a harmonious completeness of the interior furniture architecture.

How to bend mdf

Therefore, the manufacture of curved MDF facades is an integral part of progressive furniture production.

At the present level of development, the technology for manufacturing curved facades uses a special MDF board Master Form, Topan form and so on 8 mm thick. On one side, it has slots with an interval of about 5 mm, due to which it easily bends and retains its shape well. By gluing two blanks on the template, with the back side to each other, after appropriate refinement, you can get full-fledged bent furniture facades with a thickness of 16 mm.

Another, more cheap technology the production of curved facades consists in the formation of a stack thin sheets th elements smeared with glue and further bending them in special molds until the final drying of the glue.

The most important element of the technology of bent MDF facades is the manufacture of a template frame. The radius of the templates should be approximately 3% less than the required radius, since the finished bent MDF facade continues to unbend for two weeks. In width, an allowance for fasteners should be made. Chipboard residues can be used as template material.

Curved facades from MDF, as a rule, are made of sheets of smooth fiberboard or HDF 3-4 mm thick. For the first or bottom layer, laminated HDF can be used to give nice view future facade with inside.

Blanks for bent facades are cut out on a panel saw with an allowance for fixing them on a template frame and further processing.

Sheets of fiberboard or HDF, with the help of a roller, are covered with glue and stacked, and then the entire foot is fixed with screws on the template. The resulting structure is placed in a vacuum press and covered silicone membrane. The bonding process takes place in a vacuum and lasts at a temperature of working surface 40-60°C for at least 40-60 minutes.

The resulting bent blanks, after complete cooling, are sent to circular saw for cutting overhangs and bringing to the required size.

Edge milling in the absence of more complex equipment produced by hand milling machine with edge moulder. The drawing on the front side is performed on a milling and copying machine with a template.

For processing a concave surface, you will need milling machine for curved facades with a curved base, repeating the radius of the product and the corresponding pattern.

When wrapping curved MDF facades with PVC film on a membrane-vacuum press, special substrates should be used that preserve the resulting bending radius of the product.

The manufacturing technology of curved facades is quite easy to master for beginners. furniture facades from MDF. It is possible, however, to invest in optional equipment. However, as practice shows, own production bent facades costs the enterprise much cheaper than the purchase of finished products.

Curved facades from MDF and MDF profile: production technology
The most interesting and attractive for consumers in recent years has been the use by manufacturers of curved, rounded shapes as the main decorative element of a piece of furniture. The use of rounded parts makes it possible not only to obtain new architectural and artistic solutions for furniture, but also to remove sharp corners, which, according to the rules Feng Shui, allows you to create a harmonious atmosphere in the room.

With the invention of methods for the industrial production of veneer, that is, thin sheets of wood obtained by sawdust-free division directly from a log or a bar previously sawn from it, plywood also appeared, that is, material in the form of flat sheets glued from several sheets of veneer. Moreover, if during gluing, even before the glue is cured, the veneer sheets in the package can be easily bent at a fairly large angle, then after the glue is cured, the mutual displacement of the individual sheets is excluded and the material takes the shape specified during gluing, acquiring high strength to the bend. This principle is the basis for the manufacture of bent glued parts, that is, products formed from separate thin sheet elements, jointly bent when they are glued together and kept in a press until the glue is completely cured.

The production technology of bent glued furniture is constantly being modernized and improved. One of the most famous is the technology for the production of curved facades, developed by specialists from the All-Russian Design and Technological Institute of Furniture / VKTIM /, which specializes in providing technical assistance enterprises in the organization of furniture production. It allows you to make panels from a glued block of solid wood with a thickness of 4-6 mm, as well as from sawn veneer.

Constructions of the first type - based on a glued board made of solid wood with cut grooves or from several layers of glued board - the developers recommend using it without cladding, which will emphasize the beauty and originality of the texture natural wood. Finishing - transparent varnishes. Given the mentality of the Russian consumer, who, unlike the Scandinavians, is not accustomed to being used in household furniture gnarled pine and spruce wood, the surface of the part can be veiled with a translucent dye that will slightly muffle the texture of the wood without completely covering it.

How to bend MDF.

The surface of aspen cannot be treated in this way, so as not to hide its beautiful silky overflows.
The second type - with a middle layer of low-grade wood and cladding with any natural or synthetic facing material. Of particular interest are facings made of stacked mosaic shields and sawn aspen veneer. This type of construction is based on the use of low-waste technologies.

As the main unified element in the development of structures of any type, it is accepted bent part with R bending from 400 to 600mm, thickness 16-20mm. Part shape and bending radius selected based on analysis current trends in the design of furniture presented at international exhibitions in Cologne, Milan and Moscow. On the basis of such a detail as in children's constructor, by combining its various options, you can get a wide variety of surface shapes: round, wavy, with a bend in the vertical or horizontal planes. When developing designs and technologies, much attention is paid to ensuring the necessary rigidity and dimensional stability of the bent parts to be glued together, as well as their environmental friendliness. Wherein great importance have physical and mechanical characteristics glue used. Dimensional stability measurements of parts various designs showed that the details multilayer structures after manufacturing, there may be slight changes in the bending radius in the direction of its increase. The distance between the extreme points of the radius part 10 days after manufacture can increase by an average of 3-4%, which is within the normal range for bent-glued parts. After this period, the form stabilizes and no further changes occur. For parts with special embedded elements, no changes in the bending radius occur. Parts can be produced using wooden or metal heated molds, special or conventional facing presses, cold or hot. For any medium or even small enterprise, an acceptable technology option can be found for it. After gluing, machining and finishing of parts is carried out according to traditional technologies using conventional equipment.
As an example of a complete technological cycle for the production of curved glued furniture, one can cite a line offered by one of the leading suppliers furniture equipment— KAMI. A similar line was demonstrated at one of the recent furniture exhibitions in Moscow and attracted the attention of visitors. By the way, in the accompanying documentation provided by the equipment supplier, this process is named no more, no less - "fascinating".

The equipment of a furniture production workshop with the use of load-bearing and decorative bent-glued parts depends not only on productivity and the adopted production technology, but also on future design furniture. Bent glued elements can be made of peeled veneer of birch, beech, larch, pine, and MDF. The edges of bent-glued elements are most often profiled. The faces of bent glued parts are faced with sliced ​​veneer of hardwood or valuable species: beech, ash, oak, mahogany, walnut and others.

The production cycle consists of several operations. First, the veneer sheets are fed to a guillotine shear or a bench saw. Here they are cut into blanks corresponding to the size of the future veneer pack for gluing the block. The front sheets of the veneer "shirt" are cut from peeled or sliced ​​veneer and sewn together on a ribbed gluing machine. If MDF is used as the material, the sheets are fed to the panel saw and cut into blanks corresponding to the size of the future package. After guillotine shears or panel saw prepared set whole sheets enters the glue rollers, where the glue is applied and the package is formed. Formed veneer package with applied glue by using hydraulic press placed in the mold. Each of the presses has its own mold for forming its own profile, where hot pressing is carried out. Finished blocks fit into the feet, where their shape stabilizes. In the case of the manufacture of non-bearing curved glued decorative elements(e.g. facades), hot membrane vacuum press with template. The resulting bent glued blocks are fed to a circular saw or band saw machine, the overhangs of the bent glued blocks are trimmed of a relatively simple shape, and on band saw- for blocks of complex shape.

Sawed blocks are moved to planer where is created base surface along their edge. After processing, the block can be fed to a vertical milling machine with a lower spindle location and cut into individual workpieces using a set of saws, the distance between which corresponds to the specified width of the parts. The cut and jointed workpieces are fed to the thickness gauge machine for calibrating the workpieces to the width of the part. Workpieces processed to width trimming machine cut to length. For parts prepared in this way, milling machine using a profile cutter and a copying ring resting on the side surface, the edges are hemmed. Then the bent glued blanks are moved to the drilling and filler machine. Here comes the drilling of all required holes for installation of dowels, couplers and accessories. If the design of the product provides for connections that require the selection of grooves and the formation of tenons, the corresponding parts are transferred to the drilling-grooving and tenoning machines.

After mechanical processing grinding machine the processing of flat side surfaces of blanks and their ends, internal curved surfaces and external curved surfaces of parts, roundings on the ribs is carried out. Finishing grinding of workpieces is carried out using a hand-held mechanized tool.

The polished blanks are sent to pre-assembly, which is performed on workbenches-tables and in wims, where product frames are assembled. The application of a transparent or coloring primer to products is carried out in a spray booth using special guns. Then the frame is kept in the drying zone until the primer is completely cured, after which it is again transferred to the grinding department for intermediate grinding in order to remove lint and bubbles on the surface to be finished. And the whole process ends with the application of varnish in the spray booth.

These manufacturing methods have become quite widespread, especially in mass production. In the individual, especially with the growth of the welfare of the population, a slightly different technology is often used - for the manufacture of bent elements, as a rule, different kinds fibreboard, including special types of MDF type "Topan" or "Neaform". But this is an expensive imported material, besides, parts made from it need either cladding or a opaque finish.

Even a cursory examination of furniture in stores shows that the enormous potential inherent in the technology of manufacturing curved glued elements is far from being fully used. Moreover, the manufacturing technologies and areas of application of bent glued elements are simply unlimited! In addition to the use of these elements in the production of living rooms and bedrooms, the use of curved glued elements in the production of children's and school furniture. Absence sharp corners, smooth lines, collapsibility make it possible to design mobile and light furniture, providing freedom of movement for the child, excluding the possibility of injury. Another direction in which recent times bent glued elements are successfully used - this is bedroom furniture. Most widespread in it today they received flexible bed bases that support the actual mattress, which we call differently - "armor", "latoflexes". They have now become a necessary element of a bed or sofa. Armor is a typical bent-glued element in the form of a curved plate, which takes part of the total load from a lying person. But in bedroom furniture, other constructive and decorative bent glued elements are also very often used, which make up the bed frame itself - its side and backrests, elements of mirror frames, bedside tables and cabinets. The spring effect created by the bent glued element is successfully used in many design solutions. Depending on the architectural design, they allow you to create both inexpensive furniture intended for the general consumer, and elite furniture used in the most prestigious interiors.

We use (by the way we ourselves produce) a special material Master Form, for the manufacture of products of complex shape, an analogue of the German TOPAN FORM, MDF Flex. This material is made of MDF 8 mm, on the one hand its surface is smooth and even, and on the other - “cut”. This feature allows you to give the desired curved shape. If, by bending and aligning the cuts, glue two sheets, the structure will lose its flexibility and retain the desired shape. Using the Master Form saves time for the manufacture of the product.
Using the Master Form allows you to make products of various radii, saving time due to a simple gluing technology.
The material is intended for the manufacture of facades and furniture frames.

MDF board, being quite durable, easy to process and quite environmentally friendly material, is widely used in the manufacture of furniture for kitchens and bathrooms. It is convenient to use it in the manufacture of furniture with your own hands.

Sometimes, as in this specific case, there is a need to make curved facades, which you just can’t buy in a store. I want to tell you how I made MDF bent facades for a cabinet for a round washbasin in the bathroom.

How to make curved facades from MDF

For the manufacture of curved facades, we will use two MDF sheets 9mm thick - one for the inside of the facade, and the other for the outside. The facade will turn out smooth both from the inside and from the outside.

Just bending an MDF slab under a small radius, and even so that it then remains in this state, will not work. You will have to make cuts on it across the fold.

First we make a template. In my case, the shelves of the future cabinet under the sink served as a template. MDF sheets need to be cut with a margin in length and width: then you can easily cut off the excess, but it’s unlikely that you can add the missing one. Do not forget that the outer radius of the curved facades is larger than the inner one, and therefore the outer blank must be longer.

Find the centers of both workpieces and mark with dashed lines in height on both sides of the workpieces: along these lines we will then combine the workpieces with each other before gluing.

Mark the cuts until your semicircle turns into a straight plane. Each line should recede from one another by 5 mm.

Customize circular saw so as not to cut the slab too deep, and insufficient cut depth will make it difficult to bend and the slab can even be broken. The gap should be about 1mm.

Advice: Before you start making cuts on blanks for curved facades, practice on unnecessary MDF trimmings of the required length. Apply markings on them, saw through every 5 millimeters, attach one strip to the template with cuts outward, and the other on top of it with cuts inward.

Now you will know exactly how many cuts to make on each of the blanks before moving from a semicircle to a plane. You will also see that somewhere, it may not be necessary to make cuts every 5mm, and you can cut less often.

When making cuts in blanks, do not throw away sawdust - they will still be needed.

We fill the cuts on both blanks with a paste made from a mixture of wood glue and sawdust. The paste should be of such a consistency that it can easily fill the incisions, but at the same time, not too liquid. We rub the paste into the cuts with a spatula, working along the cut from the center outward so that no air pockets remain.

We dilute the glue with a small amount of water and, wetting the brush with it, pass it over both blanks, smoothing the paste and removing the remnants of sawdust.

We lay the inner blank on the template.

We lay the outer workpiece on top, combining it with the lines drawn in advance in the center of the workpieces.

We nail the workpiece one to another with thin carnations - without fanaticism, so that the carnations can then be easily pulled out. Don't be embarrassed by the fact that holes will remain from the nails: bent facades will then be primed, puttied and painted anyway.

We tighten the entire household with clamps, and leave it to dry completely.

We cut the dried workpiece the way we need it, attach amplifiers to the door for installing fittings, and grind the edges.

That's all, curved MDF facades are ready for finishing.

As you can see, making curved facades is not the fastest and easiest task, but you will have unique furniture that no one else has.

MFD very comfortable material, which is applied to furniture manufacturing, including products original form. You can bend the MFD, but this is a procedure that will require a lot of strength. To create curved facades ideal solution will become sheets with a thickness of 9 millimeters. In order for the facade to be smooth on both sides, two sheets have to be used, which as a result will be combined into one (internal and external sheets). MFD is a very convenient material that is used for furniture production, including products of the original form. You can bend the MFD, but this is a procedure that will require a lot of strength. To create curved facades, sheets with a thickness of 9 millimeters will be an ideal solution. In order for the facade to be smooth on both sides, two sheets have to be used, which as a result will be combined into one (inner and outer sheets).

How to bend an MFD panel at home?

Quite not in all cases it is necessary to process only a straight surface. If you're imaginative, you can create round or semi-oval profile décor components to vary the style, but here's how to deal with medium-density fibreboard, which has a right-angled profile.

As practice says, elastic similar material for finishing is more than likely, but under the conditions of using thin panels. Their thickness must be no more than 3 mm and exclusively for painting.

The latest and new trends in construction will tell you - a site about construction.

To bend medium density fibreboard, cut the sheet across the fold. In order for everything to go smoothly, you need to make a template that will enable the sheets to keep their shape. Next, you need to cut off pieces of the MFD sheet of a specific size, but it is best to take it with a margin (first of all, this applies to the outer sheet), after which you can easily cut off everything unnecessary.

Then, at the fold points, after every 5 mm, apply lines. Next, take the disc plate and insert the settings so that the undercut is approximately 1 mm. Then we collect sawdust, after that we mix them with wood glue and fill the holes with such a mixture. Because the mixture should resemble gruel, it is necessary to fill the holes using a spatula.

The remains of glue and sawdust are removed as follows: moisten the brush in water and brush it over the surface, carefully smoothing the paste. Lay the sheet on the template and carefully nail it with nails, which we will later remove (do not hammer them in very hard). Then we remove the workpiece, cut off everything unnecessary, cling to the fittings, paint and grind.

Hello dear friends.

In my articles, I have repeatedly drawn your attention to the fact that modern technologies the production of cabinet furniture (and the conditions for its manufacture) are such that a person, in order to make any product, needs only a project, money (for the purchase of materials and accessories), and, in fact, his own (or someone else's) hands for its assembly and installation .

But when designing furniture, any furniture maker must “play by the rules” of the intermediaries involved in this production, for example, the same manufacturers of furniture facades.

For example, such manufacturing companies have a so-called, and for the manufacture of non-standard sizes, as a rule, they take a good margin.

And if it comes to manufacturing, then the "non-standard" applies only to the dimensions of the facades in height.

In any case, the radii of such fronts will be standard (and how could it be otherwise, if the company has certain templates for their manufacture, they will not produce new templates for each “non-standard” order). There are usually three or four options (or even less).

But how does it happen that, sometimes, furniture comes across, the facades of which clearly have non-standard radii of curvature?

And this happens when the furniture maker includes in his own, quite simple (in terms of production organization) manufacturing process, their own production.

Thus, by complicating the process a little, you can make furniture that no one “in the neighborhood” makes!

For example, we will consider the manufacture of bent fronts from MDF with a non-standard radius of curvature.

The simplification of this process is that there is no need to make a special template every time.

The module itself and its crooked shelves and horizons can serve as a template.

So, each facade is made of two sheets of MDF, 9mm thick (as a result, their final thickness will be 18mm).

If you take initially a plate with a greater thickness, then a problem may arise in the manufacture of elements with a small radius.

When cutting blanks, it must be taken into account that the outer radius will always be greater than the inner one (due to the thickness of the product), and with this in mind, it is necessary to give a tolerance for the dimensions of the sheets (it is also necessary to give tolerances for the dimensions in height). They are all the same, in the process of subsequent processing will be cut off.

On the workpieces, you need to make marks of their centers, in order to then accurately fit each other.

In order to bend MDF sheets, you need to make cuts (approximately 5 millimeters apart). The cuts should be such that they do not reach the edge of the sheet by 1-1.5 millimeters.

From chips (which in any case will be formed as a result of such processing) and wood glue, you need to make a special “paste” with which to fill the resulting grooves in MDF.

The resulting mixture for this should not be too thick and not too liquid (its density can be adjusted by adding plain water).

So, when the grooves from the cut on the blanks are filled with the paste described above, they need to be fixed on the template (in this case, on the module, which will act as a template).

The front side of the MDF should be top and bottom.

That is, the first sheet lies face down on the template, and cuts up. And the second sheet lies with the cuts down (to the cuts of the first sheet) and face up.

We fix the sheets themselves on the template with the help of clamps, and the sheets are nailed to each other with boot studs.

These cloves will then need to be pulled out, and the holes that they leave on the surface of the material will be puttied during its subsequent processing.

So, we hold the fixed sheets until completely dry, after which they are removed, and their processing begins (cutting and processing edges, ends, puttying, priming, painting).

This is how, in fact, it is quite simple (and, most importantly, at home) you can make excellent facades.

And, having such an opportunity, you can make beautiful and unique furniture.

That's all.
