Packing & Delivery
The main techniques of epc include the following:
1. Pressure lost die casting technology
Pressure is epc epc technology combined with pressure solidification technology of casting technology, it is in the pressure
filling with sand box, pouring liquid metal to make foam gasification disappeared, rapid filling and sealing pressure, and access
to a certain pressure of gas, make the liquid metal solidification under pressure molding casting method.The casting technology
can significantly reduce the shrinkage cavity, porosity, porosity and other casting defects, improve the casting density and
mechanical properties.
2. Vacuum and low pressure epc technology
Vacuum and low pressure epc technology is a new casting technology which combines negative pressure epc with low pressure
anti-gravity casting.The characteristics of vacuum and low pressure lost mold casting technology are as follows: it combines the
technical advantages of low pressure casting and vacuum lost mold casting, completes the mold filling process under controlled air
pressure, greatly improves the mold filling ability of alloy casting;Compared with die casting, the equipment investment is small,
the casting cost is low, the casting can be strengthened by heat treatment;Compared with sand casting, the casting has high
precision, low surface roughness, high productivity and good performance.Under the effect of anti-gravity, the straight gate
becomes the filling and shortening channel, the pouring temperature loss is small, the liquid alloy is fed and solidified under
controlled pressure, the pouring system of alloy casting is simple and effective, the yield is high, the structure is compact;
Vacuum and low pressure epc casting has a low casting temperature and is suitable for a variety of non-ferrous alloys.

Company Profile
So-called investment casting process, simply be with fusible materials (such as wax material or plastic) into the meltability
model (referred to as "investment pattern or model), on which the coated with several layers of refractory coating, after drying
and hardening type to form a whole shell, reoccupy steam or hot water from the melt in the shell model, and then put type shells
in the sand, dry sand by filling in all round its modelling, after the high-temperature roasting cast into the furnace (such as
using degree of shell, can need not modelling and will release the shell directly after roasting), cast type or shell after
roasting, in casting pouring molten metal.
