Technological features EPC process：
 Foam-lost foundry is a newest foundry technology，is named “21CN foundry”，“Green foundry of new century”，is compared with custom foundry technology，also brings further improvements to whole foundry，as EPC castings features now：
  A． capability to manufacture specials upon request；
  B． good suitable for materials，quantity，weight，structure of castings；
  C． excellent dimensions and shapes, consistent high quality（CT6~CT9）；
  D． attractive in appearance（6.3μm ~12.5μm）；
  E． no or littler machining，significant benefit for liquid metal；
  F． littler inner defaults，dense microstructure；
  G． reducing operating strength, excellent working spot；
  H． simple processing and controlling, shorter manufacturing period，higher working benefits
