This process makes it possible to produce any three-dimensional (also undercut) workpiece geometries that are not possible using conventional mechanical or casting methods.
Depending on the casting process, a wide range of parts from small to very large can be made from all kinds of castable metals and alloys.
The workpieces cool much faster than with conventional casting processes and only slightly slower than those used in powder metallurgy.
Suction moulding (casting process) involves the use of a disposable (expendable or single-use) mould made of synthetic green sand and a pattern made of wood, plastic or metal.
