Lost Wax Casting
Lost wax casting, also called precision or investment casting is a casting technique, in which an exact duplicate of the original wax sample is being created. This can be achieved by coating successive ceramic layers on the wax model until a strong shell envelops. After melting out the wax, molten metal will be poured into the ceramic mold, creating a perfect duplicate of the original wax pattern.
The benefits of lost wax casting are greater design flexibilities, close tolerances, complex details and a smooth surface finish.
At Alumess we offer two different lost wax casting techniques:
Silica Sol with high precision, great surface quality and a fine structure and texture. It is mostly used for stainless steel alloys, but can also for brass.
- Waterglass is an economical technique with a rougher surface structure and texture. It is mainly used for coarse products and for steel alloys.
