Forging Production

The forging shop of JSC “Kopeysk Machine-Building plant” produces forgings in carbon and alloyed steel grades weighing up to 500 kg and hot forgings weighing up to 60 kg. The production capacity of shop makes 7500 t in smithing technique, 7000 t – in die forming.

The main forming equipment of the forge shop is forging and die-forging hammers (from 1 to 3.15 t) and a trimming machine. Blank heating is carried out in box heating furnaces.

The forging shop features a high level of mechanization: there are fully-mechanized lines for die forming, mechanized load and unload of blanks from heat-treating furnaces, feed of heavy stamping to the press for machine flash, two automated warehouses for print storage, etc.

The up-to date engineering procedures are also used in the shop: anchor flash-free pressing, upsetting of rod heads by the upsetter GKM-800, low-oxidative blank HFC hardening, discharge hardening of die cutting edges, etc.

FOUNDRY PRODUCTION

The JSC”Kopeysk Machine-Building Plant” foundry shop is designed for annual production of 10000 t of cast steel and iron casting and makes carbon steel and steel alloy blanks weighing from 1.5 kg to 2 tons. The pattern making and cropping shop areas are included in the foundry shop. The pattern making shop area is equipped with modern woodworking equipment. The honor of the shop area is the milling machine which provides making of cam surfaces in patterns of any complexity. The mechanized warehouse is intended for storage of the pattern equipment.

There are three shop areas in the main box of the foundry shop: electric furnace area, molding area and core area.
Smelting is carried out in arc steel furnaces of DSP-3M type.

Molding is done by the molders with flask standard size of 700х750mm to 1600х2500mm;
For mould and core making sandshale and liquid glass mixtures are used.

Topping, cleaning of castings are carried out in the cropping shop area. Cleaning of castings is done by shot blasting chambers and drums.

The operating procedures of casting making are developed by a SolidCast license program.

Heat-Treatment Production

The heat-treatment production of JSC “Kopeysk Machine-Building Plant” is characterized with wide variety of types of thermal treatment. These are bulk hardening, martempering, carbonization, nitrogen hardening, high frequency hardening, etc.
Various types of equipment are used for thermal treatment: TS-105 and TS-135 blast furnaces, chamber hardening furnaces and temper furnaces, high frequency units, salt chamber-baths, endogas units, hardening machines, etc.
The annual output of a heat-treatment shop is 8 600 pcs. of heat-treatable items.

Electroplating

Electroplating purpose is as follows: rust prevention, protective-decorative coating of a surface, wear resistance increase, electrical characteristic improvement
Accessories for all types of coatings - still-plating baths, baths of bell types.

CHROME-PLATING

Used for rust prevention of steel, copper and copper-alloy items, increase of surface hardness and wear resistance and decorative purposes. Hydraulic cylinder rods, shafts and axles are chrome plated. Maximum size, mm ф100 х1700. Coating thickness: 50-100mkm; 9-18mkm.

ZINC PLATING

Used for rust prevention of steel items (fasteners, connecting branches, angles) The procedure is carried out in a submersible bell bath. Coating thickness: 9-15 mm.

NICKEL-PLATING

Used for rust prevention, increase of conductivity and decorative finishing of steel, copper and copper-alloy workpiece surface (pins, nuts, crossbars). Carried out in a submersible bell bath. Coating thickness: 9-15 mm.

OXIDIZING

Nonmetallic inorganic coating. Used for rust prevention, decorative finishing of steel items surfaces (bench tool, couplings, and tee-joints).

SULFIDIZING

Nonmetallic coating, Sulfide film forming on the items surface decreases friction coefficients, and is effective means against wear of machine components working in friction conditions (hubs, axles, rings).
