Expendable Pattern Casting, EPC Technology


1. Technology application range applies not only cast steel and cast iron but also applies cast copper and cast aluminum. Not only applicable to geometric shape simple casting, and it’s better applicable to the castings which it’s difficult for general casting. Many castings like open side, multiple cores, complex geometry shapes which were difficult to general casting would be processed easily by EPC.

2. Under the status of slight tremors, EPC process technology can achieve pouring. To promote the forming of metallographic structure and the rank of metal fibers. It’s good for improving the mechanical properties of castings.

3. EPC technology adopts combination casting in the dry sand. Taking off sand easily, temperature progress. Thus it’s possible for heat treatment by waste heat. Especially the water toughening treatment of high manganese steel castings and solid melt treatment of heat resistant steel casting, the effect is very ideal, saving energy, shorten the processing time, and the economic benefit is remarkable.

4. Simple Processing applicables to industrialized production, the investment is 30% to 60% of sand casting, with less than the cost of general casting can obtained high precision castings which will compare favorably with wax model. wax model casting only apply to the small castings, EPC may according to melting function completes the any size of casting.

At present, In Europe, America some large enterprises such as BMW, Citroen are using EPC line, visibly EPC technology fits in with the trend of casting industry’s development today, has the broad prospect. And compared with the traditional casting technology, EPC technology has the incomparable advantage. In 1999, the EPC technology was ranked national key promotion high-tech technology by the state ministry of science, and praised as the twenty-first century casting technology, casting industry's green revolution by home and abroad.
