Precision casting is the most advanced casting technology at present. Through precision casting, semi-finished products or finished products with complex shape, high dimensional accuracy, smooth surface and close to the final shape of parts can be made, which can be directly used without processing or a small amount of processing.
Common practice is：First, according to the requirements of the product designing and manufacturing of Die Making, wax pattern making, wax pattern assembly; The original wax pattern obtained .Repeat the Coating and sand spraying on the wax pattern,Hardening shell model and drying，And dissolve the wax pattern inside,This is called dewaxing,obtained shell mold,The shell is preheat to obtain enough strength and air permeability，Metal materials for melting&pouring；Sand cleaning after shelling，So as to obtain high-precision products。According to the needs of the product or heat treatment and cold processing。
Precision casting technological process:
Wax pattern making—Wax pattern assembly—Shell making—Dewaxing—Preheat—Melting&Pouring—Sand spray—Heat treatment------Machining—Polishing—
Our rigging hardware, marine hardware, yacht accessories, pipe fitting,Car accessories are basically precision casting products, the production process is more complex, each process is the ingenuity process, so the quality is high, Industry leading.
