Precision CNC Milling Services of Vespel Plastic Housings

Gen-El-Mec Associates, Inc. is equipped to provide high reliability polymer components to leading aerospace companies. We manufactured 20 of the housings shown here using Vespel, a high-performance engineering plastic that tolerates hostile and extreme environmental conditions. Our CNC milling machine, used in combination with our CNC lathe, enabled us to keep this 5” diameter thin-walled component to within ± .0005” tolerances with the close concentricity and roundness qualities set forth in the customer specification. Both in-process and final CMM inspections validated component integrity.
