Lost Wax Precision Investment Casting Mechanical Polishing Stainless Steel Material

Precision Investment Casting / Castings of Stainless Steel / OEM Service

Product Description

Production Flow

Investment casting provides dimensional accuracy and a fine cast surface compared to conventional casting. Investment casting is also known as "lost wax casting." It involves the following five steps.
1. Mold manufacturing: Make a mold to inject wax.
2. Wax Pattern Forming: The molten wax is injected into a mold, and then the formed wax pattern is assembled on the wax tree.
3. Wax surface coating: Wax needs to be reinforced by covering it in a strong outer casing. This is done by dipping the wax tree into the ceramic slurry.
4. Metallization of the wax: Melting the wax in the ceramic casing leaves a cavity for the final casting. The molten metal is then poured into it.
5. Finishing: Break the shell and cut each part from the "tree".
We also perform CNC machining (turning, milling, tapping), welding and mechanical polishing.
