Combining EPC and casting complicate castings, it is convenient for casting designation.
2、Cutting investment and production costs
It could reduce the weight of casting bank and machining amount.
3、Without sand core
Without sand core, it will not cause different thickness and scrap caused by wrong size and setting position inaccurate in sand core.
4、High precision of casting
As non-machining and accurate molding technique, without drafting, parting surface and sand core, there is not fins, burrs and draft slope in castings, it reduces dimension error cased by core combination. surface roughness is from Ra3.2 to12.5 μm in castings surface, dimensional precision is from CT7 to CT9，finish allowance is from 1 .5mm to 2mm,it reduces machining cost sharply, and shorten 40% to 50% machining time compared with sand casting.
There is not chemical binder in sand, EPC is harmless in low temperature, sand recovery is above 95%.
