TECHNOLOGICAL PREPARATION OF PRODUCTION
When implementing the technology of casting a new part, a team of design engineers uses all the accumulated experience.
Design is performed in specialized CAD systems, at stages ranging from part modeling to mold Assembly and the crystallization process in it.
Modeling a part in 3d
Design of casting pattern
Modeling of the crystallization process
Assembling all components in the mold

PRODUCTION AREAS OF THE FOUNDRY SHOP
MOLD FORMING AREA
Molds are manufactured using the no-bake foundry process based on AL FASET resins on forming machines WÖHR, FAT, with a productivity 6 to 30 tons per hour.
Casting in sand-clay mixtures (green sand process) with using forming machines HWS HSP 2, FOROMAT 40, SAVELLI with Flask sizes 1250 x 1000 x 300 x 300mm
Forming system for no-bake foundry process – WÖHR
Cores are ready for installation in the mold

MELTING POINT
The plant of GUSSPRO is equipped with two-type induction furnaces Inducotherm 2x2t., and a single-type induction furnace ABB 2T, which makes it possible to simultaneously produce 5 tons of liquid metal.
At the GUSSPRO plant, Inducotherm two-needle furnaces ( 2x2t., 2x6t. 2x1t.) are installed. it is possible to simultaneously produce 11 tons of liquid metal.
The temperature of the liquid metal at discharge from the furnace and before pouring into the mold is measured by the Heraeus immersion thermocouple

FINISHING OPERATIONS AREA
The finishing operations section allows you to perform the following casting operations:
• Clipping;
• Cleaning up;
• Heat treatment of castings.
They are equipped with Shot Blasting chambers and thermal furnaces, as well as mine-type furnaces.
Shot blasting of castings is carried out in Wheelabrator machines
