Basic Knowledge About Investment Casting

Ⅰ. Investment casting

Investment casting, also known as dewaxing casting, is often used to produce precision parts, which can minimize material waste, energy and subsequent processing steps, and can also ensure the production of very complex parts. In investment casting, there will be a wax mold. Ceramic, plaster or plastic is used to make a shell around the wax mold and wrap the entire wax mold. During the production process, the wax mold is melted and removed in the furnace, and then the molten metal is poured into the shell for casting, and then the casting is taken out after cooling and solidification. This is the basic working principle of the investment casting.

And before the manufacturing of the investment casting products, you should understand the investment casting process and the advantages.
