Our Manufacturing Process and Equipments
Investment casting is a method of metal casting in which a wax mold is created at the beginning.
Creating a wax mold
Wax molds are created from steel tooling.
Assembling the wax molds on the wax tree
Several wax molds will be assembled with wax feedgates to create a gate & runner and creating a wax tree.
The wax tree will then dipped in a ceramic slurry then covered with zirconium sand to form a hard shell, this dipping and drying process repeated for 4-6 times depend on the size and the complexity of the casting parts.
The ceramic shell will then put inside the autoclave to melt away the wax, the cavity with shape of cast part are ready to cast
Preheat the shell
The shell is preheated to a required temperature according to the casting material and design and ready to cast.
Molten metal is poured into the shell and metal casting parts are formed.
