Deep Drawn Stamping for Precision Sealing Components


Through deep drawing, Prospect Machine Products is able to add features to sealing components that increase the capability of metal inserts in all forms of seals. The transfer press capabilities that allow us to add features such as small holes, lips, rollovers, dimples and tapers minimize our customers’ costs and enhances bonding and adhesion of the seal to the insert.

Our deep drawn metal stampings for seals can be found in:

  • Rotational shaft oil seals in gas-powered engines and transmissions
  • Valve stem seals for liquid propane engines
  • Dust and grease seals in tie rod ends, ball joints and other automotive suspension applications
  • Oil and water pressure seals
  • Water seals for name-brand home appliances

Deep drawn components for sealing technologies is a rapidly growing domestic and international market for us at Prospect Machine Products. Our customers benefit from our broad deep draw tooling selection, our deep drawing metal forming progression, and our CMM metrology, which have all been keys to our expansion in this market. Our collaborations with customers in the European Union and Asia have led to significant U.S. localization of deep draw sealing components and product lines for the automotive, appliance, and outdoor power equipment markets.

Precision Sealing Technologies

Deep draw sealing components require precision fits to be suitable for very rugged environments. To that end, we provide the ferritic nitrocarburizing (FNC) heat-treatment process to our customers as an essential value–added service performed by long-established experts. Real-time SPC data collection, cradle-to-grave traceability, and enhanced capabilities to view and measure very tight dimensions with precision on very small formed part features have increased Prospect Machine’s status not only as an approved supplier, but as the preferred supplier by our customers.
