The waxing method is also known as "melting mode". Or called dewaxing, the precise casting method of bronze and other metal objects. This method has been used in bronze casting in ancient China, and the modern precision casting is called the investment casting precision casting.The principle of lost

What is lost wax casting?Lost wax casting is also called precision casting. Artwork is also used in this way. Most ancient works of art were this way.Materials: wax, shell refractory (such as quartz sand, bauxite, etc.), binder (such as water glass, ethyl silicate, silica sol, etc.)The first step is
