Blanking production

     There are all kinds of the blanking productions necessary for manufacture of high accuracy details from colour and black metals and alloys at ANTONOV ASTC. Among them are:

     Blacksmith’s production

Manufacture of forgings by open forging from colour and black metals and alloys including the following ones:

• АМц, АМгб АК6, АК4, В95, 1933, В93 aluminium alloys;
• ВТ 1-0, ОТ4, ОТ4-1, ВТ6 titanic alloys;
• М1, М3, ЛС59-1, Л63, БрАЖЮ-4-4, БрАЖМц 10-3-1-5 copper alloys;
• Steels: carbon, alloy and high-alloy, tool.

     Manufacture of forgings of rectangular and round profile with maximal weight of up to 50 kg;

     Manufacture of forgings with bending and insertion operations carrying out, maximal outside diameter of inker circles is 280mm;

     Manufacture of bolts with hexahedral head. Diameter of rod for thread is M10-M27. Materials are 3ОГСА, 40ХН2МА. Manufacture of bolts from carbon steel;

     Manufacture of various residential units with decorating forging.

     Foundry

     Manufacture of mouldings for structural and non-structural purposes from aluminium, copper, magnesium alloys, steels, foundry iron by method of foundry into sand forms, on investment patterns, into ceramic forms. Range of the mouldings weight is from 0,01 to 50 kg, dimension – from 50 to 700mm;

     decorative foundry from copper, aluminium alloys, steels;

     manufacture of foam aluminium under foundry and powder technologies;

     refining of metal wastes (cuttings, spoilage, return and so on) into secondary alloys.

     Powder metallurgy

     Manufacture of souvenir production (medals, trinkets and so on);

• Manufacture of friction materials on the base of copper and iron (brake linings and discs of different configuration);
• Manufacture of antifriction materials (sliding bushing, self-lubricating bushes both with lubrication and without it, working range of temperatures is up to 500ºC )
• Manufacture of details with polysurface of friction, with baked bronze powder and sodden with fluoroplastic (nuts);
• Manufacture of hard-alloy production;

     Gasometric plasma spraying with purpose of:

• protection of outside surfaces from corrosion and wear and tear of equipment;
• restoration and repair of life-expired surfaces;
• metal fluoroplastic coating;
• plating of plasma coating on inside surfaces of details (with diameter of more than 100 mm);
• plating of pulse and plasma wearproof coatings with big thickness and adhesive strength).

     Materials: tin and aliminium bronze, nichrome, Ni, Ni-Al, Ni-C, ПТ-19-Н-01б Мо, Al2O3+TiO2, Cu-C, Bronze-Cu-C, BKHA.

     Welding fabrication

     Argon arc welding of aluminium, steel, titanium both with the further reinforcement with heat treatment and without it;

     Manual arc welding with coated electrodes;

     Automatic argon arc welding of details from steels, titanium including pipelines;

     Contact spot and seam weld;

     Soft and hard soldering.
