Production of blanks

Oxygen cutting

The type of cutting represents burn of metal in an oxygen jet. Oxygen jet cuts heated metal and removes resulting oxides simultaneously. Low-carbon steels are the easiest to cut this way.

Маximum dimensions of steel sheets processed:

  • 2500×12000 mm, thickness 8 to 300 mm.

Plasma cutting 

The type of cutting represents continuous fusing of blank’s material with electric arc’s plasma jet including simultaneous removal of resulting melt products and creation of required cut.

Маximum dimensions of sheets processed:

  • 2500×12000 mm;
  • Stainless steel sheets, thickness 20 to 60 mm;
  • Sheets of titanium and aluminum alloys, thickness 20 to 100 mm.

Мicro-plasma cutting

Micro-plasma cutting is one of varieties of plasma cutting. Micro-plasma cutting machine, design-wise, is in fact a small-sized plasmatron.

Маximum dimensions of sheets processed:

  • 2500×12000 mm;
  • Stainless steel sheets, thickness 20 to 60 mm.

Hydroabrasive cutting

Hydroabrasive cutting is performed with jet of pressurized (up to 4000 atm) water mixed with abrasive material.

Hydroabrasive cutting machines are used to finish machine parts, or blanks with minimal allowance, as well as intricate curvilinear profile blanks made of any sheet material with minimal cut width, including titanium alloys without any heat treatment, avoiding generation of oxide film and surface defects within the cut area.

Маximum dimensions of sheets processed:

  • 2000×6000 mm;
  • Steel, titanium and nonmetal sheets, thickness 1 to 100 mm;
  • Aluminum sheets, thickness 1 to 160 mm.

Laser cutting

Laser cutting is one of advanced methods of sheet materials’ processing which represents the focused impact with laser beam. This method is distinguished from other cutting methods by its high processing rate as well as impeccable quality of cut and acceptable cost.


Computer numerical control (CNC) laser cutting machine.

Маxumum dimensions of sheets processed:

  • 1500×3000 mm;
  • Steel sheets, thickness 0.5 to 6 mm;
  • Aluminum sheets, thickness 0.5 to 5 mm.

Band-saw cutting

Among advantages of band-saw cutting are: it cuts metal clean, leaves no burrs and beadings, provides smooth cut edge that does not require further surface machining, does not deform hollow roll stock edges.
It provides an opportunity to cut round, hexagonal, square and hollow roll, cross-section 50 to 460 mm made of structural, stainless, heat-resistant steels, titanium and aluminum alloys.


It provides an opportunity to cut round, square, hollow, hexagonal roll having cross-section 50 to 460 mm made of structural, stainless, heat-resistant steels as well as titanium and aluminum alloys.

Abrasive cutting

Abrasive cutting is performed by cutter wheels, saves time and material. The resulting cut is more regular and often does not require further processing.

We can cut the following types of rolls:

  • Hollow, cross-section 18 to 50 mm;
  • Round, cross-section 20 to 50 mm;
  • Hexagonal, cross-section 36 mm max;
  • Angle bar, cross-section 20×20×3 to 80×80×8;
  • Structural, stainless and heat-resistant steels, titanium and aluminum alloys.

Shears cutting

It provides an opportunity to cut roll having cross-section up to 20 mm and length 2500 mm maximum as well as the following rolled sheets:

  • Steel, thickness 0.7 to 6 mm, length 3000 mm max;
  • Aluminum alloys 0.7 to 10 mm, length 3000 mm max.

Hydraulic explosion stamping

What hydraulic explosion stamping does is it deforms sheet blanks by applying shock wave’s pressure generated by explosive detonation. The method’s advantage is the opportunity to produce parts from high-strength alloys as well as high cost efficiency resulting from reduced time and cost associated with preparation of required production infrastructure.
Hydraulic explosion stamping allows to produce blanks with maximum diameter of 1800 mm from sheets 1.5 to 12 mm thick.

Stamping with Hydraulic and Crank pressing machines

This technology can produce sheet blanks with diameter 1050 mm maximum and the following thickness:

  • Steel and aluminum alloys sheets 0.5 to 6 mm;
  • Titanium alloys sheets 0.5 to 3 mm.


Sheet metal bending is an up-to-date technology that provides a lot of advantages. It allows to produce customized parts. Available for you to order are bent parts of various designs that will be made in full compliance with Customer’s Statement of Work. Hydraulic vertical bending press having 170 tons operating force allows to bend sheets, profiles, U-section 0.5 to 6 mm thickness and length up to 3000 mm.


3D pipe bending on CNC machines with optical control on a measuring center.
CNC pipe-bending machine allows to perform 3D pipe bending, provides desired dimensions and minimal deviations from required 3D numerical model. Pipes from 6 to 32 mm in diameter and 2500 mm maximum in length can be bended.
The optical control and measurement system allows to control pipelines bent in several planes using optical non-contact method that engages 16 digital video cameras ck edges. Diameter of pipes that can be measured are 3.2 to 200 mm and 2500 mm max. long.

Rotary drawing

Rotary drawing is production of thin-walled parts and blanks – rotary bodies of different shapes through deformation of metal with roller that implies reduction in original thickness of part and increase of its length. Rotary drawing can be performed with and without having to heat the material.

Manufacturing of parts (blanks):

  • Shells, cones, shrouds of aluminum, titan alloys and special steels, thickness 0.5 to 8 mm and Ø 60 to 2390 mm with having to heat the material;
  • Cylinders, cartridges of special steels and aluminum alloys, thickness 0.5 to 5 mm, Ø 60 to 480 mm, and length 2000 mm max. without having to heat the material.
