What Is Investment Casting
Investment casting is a manufacturing process in which a wax pattern is used to shape a disposable ceramic mold. Then this is usually cast with molten metal, such as carbon steel castings, alloy steel castings and stainless steel castings. This process can also be referred to as “precision casting” or “lost wax casting”.

Steel Investment Casting Process – Ningbo Investment Casting Co., Ltd
1. The first step in the Steel Investment Casting Process is to produce a wax replica of the desired part. This is accomplished by injecting wax into an aluminum die cavity.

Lost Wax Casting Tooling Pattern made by Ningbo Investment Casting Co., Ltd
Wax Pattern tooling is necessary for all investment castings. The tool is made from high grade aluminum, and designed to accept the flow of molten wax under extreme pressure, in order to allow it to solidify into the wax pattern which is used to form the ceramic mold during the investing process. Unlike sand casting, lost wax tooling replicates the final casting in reverse, due to the fact that we cut “cavities” in which the wax flows to form our patterns.
