Plaster and metal castings - Inc.

 Custom-designed plaster and metal castings for parts from 3D CAD models have been added to the company’s product line.
Plaster molds are created using a rubber mold from an rapid-prototype-generated pattern. The rubber mold is used to create plaster molds for casting production. Plaster casting serves as a precursor to die-casting production while the hard tool is being made. The die castings are made from nonferrous metals, specifically aluminum, zinc, copper, and magnesium, although ferrous-metal die castings are possible. The die-casting method is suited for applications where large quantities of small to medium-sized parts are needed with good detail, a fine surface quality, and dimensional consistency.
