Steel precision casting, as its name implies, is the casting process for precision parts. This type of casting method is actually a lost wax investment casting process, which will be able to produce net or near net shape, high-dimensional accuracy and intricate design.
In precision casting process, the first step is to build a wax version of the final product, whose dimensions are the same as finished castings.

This can be done in 3 steps:
1. Design and manufacturing a pair of metal mold according to the 3D model of the part. (Offered by purchasing company or casting engineer).
2. Create wax patterns, which have the same shape of castings, and repeat this process until the quantity of wax patterns is the same as order quantity of castings.
3. Inspect and repair wax patterns, and assemble them like a tree.
