Plaster mold castings

Smooth surface finishes reduces clean up time.


        - multiple cavity molds from single model

        - cast in undercuts


Ceramic mold castings


Most costly method but has the ability to closely reproduce fine details and textures.

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 ± 0.025 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.
