Design and Metallic pattern
Mettallic pattern for wax injection molding to make lost wax mold
is made of aluminum, steel etc. and is designed in various way to
satisfy a suitable shape.
Injection and Issembling of wax mold
Liquid or semi-solid wax is injected in a various shape out of metallic
pattern, or ceramic core or soluble wax can be used to make the shape
with undercuts or complicate shape.
Wax tree which is assembled with many wax molds is made for the economic
design.
Mold making
The wax tree is immersed into slurry and sprinkled with a molding
sand
and then the mold is made in the dry chamber having a suitable temperature
and humidity.
Through repeating this process over 7 times the mold having requested
hardness is made.
Finally we get the mold for casting by removing a wax inside of it
with a high temperature and pressure steam.
Casting and after treatment
Plastic mold is boiled over 1000'C for 2 hours
to enhance casting performance and to get a good casting iron product
after casting, cutting, removing gate, surface treatment are made.
Testing and quality control
