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.
