CPS TECHNOLOGIES CASTING PROCESS PRODUCES NEAR NET-SHAPE COMPONENTS

The process for producing either discontinuous, particle reinforced or continuous fiber reinforced part starts with a preform that has the shape of the final part. The preform is then infiltrated with aluminum to produce a metal matrix composite component. This process is similar to the polymer composite process called resin transfer molding, except the preform is infiltrated with molten aluminum rather than resin.

EXAMPLES OF METAL MATRIX COMPOSITE PARTS

CPS Technologies has been the leading producer of metal matrix composites for thermal management of electronics for over twenty years and has produced millions of LIDS, IGBT’s and other specialized components which combine our unique Quickset™ performing capability (Silicon-Carbide particulate performs) with our casting processes. We have now expanded that capability by demonstrating components for mechanical, structural and armor applications. Shown below are a few examples. Our current equipment capabilities allow us to process parts that will fit in an envelope of 17 x 32 inches (80 x 40 cm).
