Detail Information AboutGreen Sand Casting PC002

The green sand moulding process requires sand, clay and water to be mixed together to form a mould material that can be compacted around a pattern to produce a mould. Water develops the bonding characteristics of the clay, which binds the sand together, when used in its moist condition it is referred to as green. The green sand process can be used to produce castings in both iron ,aluminium as well as copper based metals. The process allows 90% to 95% reclamation of material and so provides a low cost form of production.

Various high quality castings are made of gray iron, ductile iron, aluminum, steel, 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 microstructure analysis, as well as checking tensile, impact strength and surface hardness by physical test and magnetic particle etc.
