Capabilities & Services

Through the offerings of our five Divisions, our capabilities run the gamut – we make parts from 0.016 (0.4mm) to 40.0 (1,016mm) inches in diameter. We are able to handle all aspects of material formulation (R&D through production), tooling, forming, sintering, machining, as well as the diverse offerings of our secondary operations. We have experienced Sales Engineers available to assist in determining the feasibility of using our products in your design.  If you would like to contact a representative about a feature/offering we do not have listed (or have an inquiry on our offerings), fill out our contact form here.  Or simply call our office.
