Precision casting

Samara gypsum plant offers high-strength gypsum to the enterprises of mechanical engineering, aircraft building, and jewelry industry.

Gypsum mixtures for high-precision casting are used for the manufacture of molds in the production of metal parts in the aircraft industry, mechanical engineering, as well as in the jewelry industry.

when casting low-melting alloys (not higher than 200-320 C) for the manufacture of injection molds, the use of "pure" gypsum is possible. When casting alloys with a higher melting point (up to 1100 C), gypsum molding mixtures are used, in which high-strength gypsum (25-40%) is used as a binder of refractory fillers. Thus, the molding mixture for high-precision casting is a mixture of high-strength gypsum, refractory filler and special additives.

High-strength plaster GVVS-13 and GVVS-16

High-strength plaster GVVS-13 and GVVS-16-material for creating models of parts.

Main advantages of GVVS-13/16 application:

• Rapid hardening, ensuring the readiness of the model in a short time.
• Early set of maximum strength-7 days, which is 4 times faster than cement mixtures.
• high fluidity of the mortar mass, ensuring accurate, smooth and clean casting surface.

Models cast from high-strength plaster produced by CJSC "SGK" allow you to create accurate injection molds.
