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.

Tools for Deep Draw Metal Stamping – Important Facts

Why Tool Design and Maintenance are Critical in Deep Draw Metal Stamping

By Anthony Romero – Sales and Application Engineering Manager

The design of deep draw tooling is based on engineering data, simulation, and external software modified with internal concepts. Some of the items that are considered are work piece material properties, draw reduction ratios, clearances, press speeds, blank holder pressure, and others.

However, there is metal-forming expertise that is involved as well. This is where our toolmakers interact with the assigned engineer to optimize the tooling based on historical data and expert knowledge. As mentioned in our blog on the “importance of mentorship” in our industry, it is crucial for the experienced toolmaker (i.e., the metal-forming expert) to pass their insights on to apprentices in the team. (Check out “The Experts Among Us” by Peter Ulintz in MetalForming magazine, March 2017.)

The Many Tooling Considerations in Deep Draw Manufacturing

We take many considerations into account regarding the tooling for our deep drawing applications and projects. For example, the number of stations is based on the draw and complexity of the part. The photo above shows a process that requires 10 stations and the respective punch and die, as well as the fingers that are required to transport the work piece from one station to the other.

Another variable to be considered is the estimated production volume. The material chosen for some of the punches and dies will depend on this volume and the actual load calculated during the deep draw operation. Special coatings or tool steels might also come into play (carbide coatings, A2, or M2 material), depending on the potential volume and high loading.

Taking Responsibility for Tooling

It is important to keep in mind that a reputable deep draw metal stamper like Prospect Machine Products (PMP) assumes all liability for the tooling for the service life of the work piece – potentially several years. This is a critical concept, since tooling costs can be significant. But with PMP, it is a one-time investment.

Offshore competitors understand this barrier to entry, so they amortize the tooling cost on the piece price to soften the initial financial impact. PMP doesn’t use this somewhat deceptive tactic, since the customer might end up paying several times the initial tooling cost when the project or the production part lasts several years.

Tooling Forensics Extends Tool Life

Another place where the toolmaker’s skill and experience are valuable to the customer is in what is referred to as “tooling forensics.” PMP’s toolmakers inspect all tooling for irregular wear, chipping, or other early degradation after the initial runs and setups.

Then, light design modifications and lubrication changes are made to increase the life of the tooling. This important step has a positive impact in keeping lead times short and helping to ensure on-time delivery (OTD).
