WHAT CASTING PROCESS WE ARE GOOD AT?
Investment casting is an industrial process based on and also called Lostwax casting, one of the oldest
known metal-forming techniques. The Investment Casting process begins with producing a heat disposable
pattern. This is accomplished by injecting wax into a metal die. A pattern must be molded for every casting.
These patterns are assembled into a cluster (or tree) and are then coated with various liquid ceramic refractories to form a ceramic shell. The wax is then melted out of the ceramic shell. Any number of different alloys can be cast into the ceramic mold. After cooling, the ceramic shell is removed and the castings are cleaned.
Our investment casting process:
a)Silicasol casting process( maintains typical tolerance accuracy within CT4-CT6 standard,
with a surface finish of Ra3.2-6.4)
b)Soluble glass casting process(maintains typical tolerance accuracy within CT7-CT9 standard,
with a surface finish of Ra12.5)
c)Lost-foam casting process
d)Combining silica sol casting process with soluble glass casting process:
the price is lower than silica sol casting process, and higher than soluble glass casting process; the quality is also in the middle of this 2 processes.
