Deep Draw Components in Sealing Technologies

By Richard Laurenzi (President) and Anthony Romero (Sales and Application Engineering Manager) –Prospect Machine Products – July 22, 2019Deep drawn mechanical sealing components

Deep drawn mechanical sealing components is a rapidly growing domestic and international market for us at Prospect Machine Products. PMP 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.

What’s more, 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, outdoor power equipment markets, and more applications.

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

Sealing Applications

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

  • 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
  • Oil seals for name-brand home appliances

Deep Draw & Seals – Special Requirements

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 skilled and experienced experts. We also provide real-time SPC data collection, cradle-to-grave traceability, and enhanced capabilities to view and precisely measure very tight dimensions and rollovers without a gap on very small formed parts.

A very critical requirement on some of these seals is the no-gap specification in the roll over of the lip. Otherwise the insert is considered faulty due to the engineering design. This is where the know-how of the toolmakers and engineers becomes paramount, since especial deep draw tool designs are needed. Additionally, the lots are sampled during the production by sectioning several parts and visually ensuring that there is no gap in the rollover under high magnification.
