When it comes to the
investment casting process for metal parts, factors such as design requirements, cost, and manufacturing feasibility determine which casting process is best for manufacturing the product.
Investment casting produces precision components while minimizing material waste, energy and subsequent machining. It also ensures the production of very complex parts. This makes the investment casting process very useful for design engineers.
What exactly is an investment cast by "investment"? The word "investment" has historically had the meaning of "covering" or "surrounding". Investment casting uses a shell of ceramic, plaster, or plastic that is formed around a wax pattern. The wax pattern is melted and removed in a furnace, and the metal is poured into the shell to form the casting.
