Green Sand Casting

Saivs is equipped many facilities for the green sand molding, and the resin sand molding. Various high quality castings are made of gray iron, ductile iron, aluminum, brass etc.
Quality control checks are performed throughout the casting process form screening the raw material for stability the concentration of alloy and melted by the electric furnace. We analyze the chemical elements concentration of the alloy with spark spectrometer testing before casting.
After casting and heat treatment we continue testing by metallurgical microsturctural analysis, as well as checking tensile, impact strength and surface hardness by physical test and magnetic particde etc.
