Sand mold castings

Most economical process. For simple shapes where ease of clean up does not warrant paying for finer finishes.

Plaster mold castings

Smooth surface finishes reduces clean up time.

Versatile:

        - 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.

Leatherettes, woodgrains or any difficult to cast textures can be incorporated into models for duplication on casting surfaces.

Size

From small blister packs to large dunnage trays


Unique Capabilities

Multi-impression molds produced from single model

Male or female molds produced from male or female models

Cast in water lines for better heat transfer

Blow Molds

Rotation Molds

Matchplates

Prototype and short run castings

    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.
