Plaster and Metal Casting Now Offered for Custom Parts

Thu, 07/09/2009 - 12:49pm


Rapid Prototyping (RP) is often used with plaster molding processes to circumvent or transition to the production of hard tooling. This is accomplished by creating a rubber mold from an RP-generated pattern. The rubber mold is then used to create plaster molds for casting production. Plaster casting often serves as a precursor to die casting production while the hard tool is being made. Die casting, a form of metal casting, is the process of forcing molten metal under high pressure into mold cavities. Most die castings are made from non-ferrous metals, specifically aluminum, zinc, copper, and magnesium, although ferrous metal die castings are possible. The die casting method is especially suited for applications where large quantities of small to medium sized parts are needed with good detail, a fine surface quality and dimensional consistency. Die casting technology has been advancing rapidly during the past twenty years, particularly in the last decade.
