What is Investment Casting?

Investment casting, also known as lost-wax casting, is one of the oldest known metal-forming techniques. The reason why investment casting goes its name is that the process invests the wax pattern with refractory materials to form the mold, and the molten material is cast into the die. The shape of the cavity inside the mold is an exact duplicate of that of the desired product. Common materials used in investment casting including stainless steel, carbon steel, aluminum, and brass. Investment casting has been used in the last 5000 years, in the earliest time, beeswax was used to form the patterns, later, more advanced waxes are applied to make the wax mold. Most of the wax used in lost wax casting can be recycled. Investment casting is a popular manufacturing way because it is capable of producing parts with high accuracy, repeatability, and integrity in a variety of metals and alloys.

How Does Investment Casting Work? – Investment Casting Process

Investment casting (lost wax casting) is the process of using wax to make the mold of the parts to be cast, and then the wax mold is coated with mud, which is called clay mold. After the clay mould is dried, heat and melt the inner wax mould. Take out the clay mold after melting the wax mold and bake it into a ceramic mold. Generally, the gate system is left when making the mud mold, then the molten metal can be poured into the mold. Cool it until the part solidifies, the required parts are made.
