Qingdao Shengmei Machinery Co.,Ltd | Updated: Aug 27, 2018

Lost Foam Shell Casting Technology

EPC technology is a new casting method which combines investment casting technology with EPC technology. The method is to coat several layers of refractory materials on the surface of foam mold which is similar to the shape of parts. After hardening and drying, the foam mold is burned and gasified to form a shell. After calcination and pouring, a new type of precision casting with higher precision is obtained. Method of making. It has the characteristics of large pattern size and high precision in EPC, as well as the advantages of precision and strength of crust in investment casting. Compared with conventional investment casting, it has the advantages of low cost, convenient pattern bonding and combination, easy vaporization and disappearance. It overcomes the problem of investment mold deformation caused by easy softening of investment casting mold, and can produce large-scale complex alloy castings.
