We are a full-service firm, not dedicated to a single process or production of a single product type, so we often have extra capacity for contract jobs in one or more of our activities – machining, assembly, testing, etc. We make this available at competitive rates.

Contract work • Machining of thermoplastics, thermosets, composites, and exotic metals • Clean room assembly • Laboratory testing services • Incandescent digital readouts, displays, and indicators • Prostheses of titanium and 7075 aluminum • Fine stainless steel and titanium surgical instruments

Please contact us today with your needs. Read on for examples of our specialized custom work...

Contract work, custom & special manufacturing
For machining, we offer a wide variety of equipment, from manual tool-room machines all the way to 5-axis CNC machines. We work easily from your blueprints or electronic CAD drawings (in all major formats – AutoCAD, SolidWorks, Pro-E, etc.), or even directly from solid-model files importable to MasterCam such as STEP, Parasolid, IGES, etc. Just contact our engineering department regarding the compatibility of your preferred format.
