Slurry And Shell-making Of Lost Wax Casting

Slurry and shell making is a small step in the lost wax casting process. Usually, after the wax model is made, the surface is dipped with a slurry of silica first, in order to allow the granular material for shell making to stick to the surface. After dipping the surface will have adhesion, then the surface is drizzled with ceramic shell mould material until the entire surface is completely covered, and then it is dried, which is a simple process of slurry and shell making. In this process, it is also necessary to reserve the casting chasing so that the internal wax can burnout. This is a process of losing wax, which is convenient for subsequent casting.
