How does the plaster mold casting process work?
First, we construct a positive tool similar to the eventual casting, only larger to allow for material shrinkage during solidification. After the establishment of parting lines (the same parting lines used by the die casting process), slurry plaster is poured onto the tooling halves, allowed to solidify, extracted, dried, rejoined and molten material is introduced. After solidification of the cast metal, the plaster is broken off. The result is a simulation of a die cast part.
