The three elements of die casting are die casting machine, die casting alloy and die casting mould. Sieg-Huao has a professional team dedicated to the design and production of die casting molds. Only good tools can produce qualified casting parts.
Die casting is a metal casting process that is characterized by forcing molten metal under
high pressure into a mold cavity.
Finishing for die castings mainly include deburring, grinding, polishing, cleaning and
secondary machining by cnc machining center.
Wax injection is the process of using wax injection machine to inject the liquid wax
into the metal mould and to inform the wax pattern.
Wax assembling refers to gluing each wax pattern together with another from the
position of in-gate to a tree-like fixture.
The wax trees are dipped in a ceramic based slurry and then showered in a very fine silica
based mixture again and again to finally get a shell with desired wall thickness.
Dewaxing kettle is used to heat the shells in order to melt away the wax and finally get an
empty shell cavity.
Shell baking: After de-waxing process there left an empty shell. The shell is put into
the furnace to get baked in order to achieve enough hardness and is prepared for
high casting temperature during pouring process.
During pouring process, the solid metal is melted into liquid in the furnace and then poured
into the metal moulds after baking.
Post Casting Treatment mainly refer to CNC machining which includes cleaning,
drilling, milling, turning, threading and so on.
