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
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.
