1. Introduction to Investment Casting

Investment casting, also known as lost-wax casting, is a manufacturing process used to produce intricate and high-precision metal casting components. The process dates back over 5,000 years, with early applications found in ancient Egypt and China. Today, it is widely used in industries such as aerospace, automotive, medical, and industrial machinery due to its ability to produce complex geometries with excellent surface finishes.

Investment casting, also known as “lost wax casting”, usually in the wax mold surface coated with several layers of refractory materials, to be hardened and dried after the wax mold melted away and made of shell, and then after baking, and then pouring, and obtain castings of a method, due to the casting has a high degree of dimensional accuracy and surface finish, so it is also known as “melting precision casting”.
