Prototype and short run castings Electronics, Automotive and Commercial applications With 50 years of experience producing Aluminum and Zinc castings, we can offer a unique method of prototyping for Die Casting applications: Dimensional Accuracy: The Plaster Mold Process can achieve castings with dimensional accuracy and surface finish similar to Die Casting. For Example: Surface Finish: 90 - 125 RMS ( Root Mean Square ); C60 maximum on Visual Surface Finish Comparator Sample Chart. Linear Tolerances: General +/-
0.005 in/in from 0 to 6 ins; +/- 0.003 in/in
thereafter, with maximum tolerance
of +/- 0.040 ins. Virtually
any size or shape of Casting can be produced by this unique method of
prototyping. Low unit runs or up to several thousand castings can be readily achieved economically. From 1 oz. to several hundred pounds in weight. Heavy sections or wall thicknesses as low as 0.060 ins. thick. Excellent duplication of intricate designs. Reduce or even eliminate machining. Short Lead Times. Low Tooling Costs ..... and more.
