Metal structures and mechatronic devices

Plasma cutting of metal is a modern, fast and accurate way of processing any type and thickness of metal. Plasma cutting technology was developed over 50 years ago.The process consists of melting at a temperature of 6 to 30 thousand degrees, and subsequent removal of liquid metal by plasma flow. Plasma is an ionized gas with a high temperature capable of conducting an electric current. With the help of special equipment and computer control, plasma cutting allows you to cut from a single sheet of metal elements of any size and form, which allows you to make a variety of engravings and individual orders.

Numerical software control used to achieve the highest accuracy and efficiency of metal cutting on special machines. This method of processing steel, aluminum, copper is used in situations where it is necessary to make metal billets on time and with the highest level of compliance with the specified parameters.

The advantages of this method of cutting include:

speed of work performance;
ability to work with various alloys;
no deformations on the finished product;
high cutting accuracy;
there are no restrictions on the size and form of the metal;
no harm to the environment.

LAZER CUTTING

Laser cutting of metal allows to receive a figured pattern and a smooth edge of a cut without scale.
Compared to plasma, laser cutting of metal is cheaper. This method of metal cutting makes it possible to implement any thread and design to satisfy the most demanding customer. After all, with the help of clear drawings and a laser, you can get the maximum accuracy of the part.
Laser cutting of metal is a virtually waste-free production. The process of laser cutting is usually ordered in combination with other types of sheet metal processing, such as metal bending, welding and powder coating. As a result, the finished product will have perfect accuracy of angles and sizes.
The laser makes it possible to obtain the smallest holes and incisions. It should be noted that the laser is the safest for metal that has a mirror or glossy surface, because it does not leave damage.
We implement any design solutions related to the design of metal products and structures with elements of laser cutting. An important advantage of this method of cutting metal compared to others is the low price, fast order fulfillment and high accuracy.

Grinding of metal

Grinding of metal is a finishing operation for processing parts for various purposes. Without this operation, it is impossible to obtain a fully finished product that meets the technological requirements. Grinding of metal allows to bring a detail to the necessary parameters with the correct geometry and with the set parameters of roughness of a surface.
Grinding of metals is carried out by means of abrasive materials during which the top layer is removed. This treatment is performed by grinders, which are portable (manual) or floor (for processing large surfaces).

Depending on the shape of the surface to be treated, grinding can be of different types:

round;
deep processing;
centerless;
peeling;
flat;
profile.

Each of these grindings can be performed inside or outside the product. Round grinding provides high accuracy of performance of works. Flat grinding is most often used to process equipment, as well as parts that have flat surfaces.
Special tables are used for this method for convenience. Peeling is used to process metal products that may have a defective layer after casting. When grinding by the peeling method, coarse-grained abrasive wheels are used. Deep grinding is one of the types of peeling, it can be attributed to the finishing of the casting.

HEAT TREATMENT

The essence of heat treatment is to change the structure of metals and alloys in changing their mechanical and physical properties. There are three stages of heat treatment:
1. Heating to the required temperature;
2. Exposure at this temperature (1 minute per 1 mm cross section of the part);
3. Cooling.

All metals and alloys consist of crystalline grains. When heated to the desired temperature, most crystals are destroyed. During abrupt cooling, many small crystals are formed at the site of the destroyed crystal and a fine-grained structure is formed. The smaller the crystal, the stronger they are interconnected, as a result - greater hardness. However, internal stresses are formed, which give the hardened part fragility. Upon subsequent heating to low temperatures, the crystals begin to melt. This process leads to internal stress in the crystals and, accordingly, reduces the fragility. Upon further heating, the crystals are destroyed.

Our specialists are well versed and have practical experience in heat treatment of metal. We carry out both small one-time orders and complex projects related to metal processing.

BENDING OF METAL

The process of bending a metal is to change the position relative to another, while the place of bending stretches the outer layers of metal and compresses the inner. Between them is a neutral layer, which does not feel any compression or tension - this is a neutral line, which calculates the length of the expanded plane of the workpiece.
Bending can occur in the following ways: machine and plastic deformation.
In machine bending, a V-shaped matrix is used, which pushes the sheet into the matrix, forming a bend with a given angle, the bend radius at the desired length.

When bending, only the area of the workpiece in the area of contact with the punch is plastically deformed and the outer layers are stretched, and the inner (facing the punch) are compressed. When removing the load, the stretched layers of the workpiece are elastically compressed, and the compressed ones are stretched.

There are two main methods of bending:
free bending - a case of bending, when there is an air gap between the sheet and the walls of the matrix (the most common option);
calibration - if the sheet is completely pressed against the walls of the matrix.

Our company has many years of experience in providing this service. We know how to calculate all the details and nuances including the specifics of each type of metal.

POWDER COATING

Powder coating technology is the most modern and high-quality method of painting. This method of painting includes the following stages: surface preparation, powder coating, polymerization process.

Surface preparation is the most important stage, because the quality of the finished coating depends on the quality of the prepared surface. If you do not pay enough attention to surface preparation, you can not avoid the problem of peeling paint, bubbles and metal corrosion. The process of preparing the metal for further application of the paint includes: cleaning the surface from contamination, degreasing and drying.

The next step is to apply a powder coating. This is the process of applying dry powder to a metal product in a spray chamber. The coating is applied using electrostatic equipment. Powder paint is electrically charged from an external source or by electrification by friction. With the help of an electric field, powder paint particles are transferred to a product that has the opposite charge. Powder paint particles that have not settled on the product are trapped in the spray chamber, and this paint can be used for re-spraying, which is not possible when using conventional liquid paints.

The last step in the powder coating is the polymerization process, which consists in transferring the product to the polymerization chamber for baking. The polymerization process takes place at a temperature of 170-220 ° C and lasts 20-30 minutes The temperature and polymerization time depend on the type of paint and the thickness of the metal. In the process of baking, the powder melts and forms a film on the surface of the product. The last and final step is to allow the product to cool so that the film hardens.
