Choosing The Right Engineered Seals For Your Application

When you need engineered seals, you are concerned about both quality and cost. Especially in industries where your products are disposable or where you need high-volume, you want to make sure that your seals are produced quickly and affordably. When you purchase engineered products from Performance Seal, you are acquiring the expertise of the Parker Engineered Seals Division (EDS), which specializes in streamlined manufacturing processes.

What Type Of Seals Do You Need?

While any type of seal you need for your application can be custom molded, many seals fall into certain categories of products such as:

  • Fuel cell seals
  • Axial and radial seals
  • Fuel system seals
  • Oil seals
  • Diaphragms
  • Radiator coolant seals
  • Appliance seals
  • Grommets
  • Bumper
  • Fuel system isolating components
  • Valve components
  • Agriculture components
  • Poultry picking fingers
  • Miscellaneous isolating components

Performance Seal will work with you to find the best design for your application. The company has years of experience in designing elastomeric or metal/plastic retained elastomeric combinations in a variety of materials that meet ASTM standards, as well as the regulations that meet industrial standards
Most seals fall into one of these categories:

  • Homogeneous Rubber. Low-cost and producible in most configurations, homogeneous rubber seals can incorporate design flexibility, sealing beads, or retention features, and offers many functional advantages over traditional round cross-section or flat sealing products.
  • Subassemblies and Finishes. Comprised of multiple parts that range from two to several, assemblies include seals and fittings that can be coated to cut friction in some applications.
  • Rubber-to-Plastic Bonded Shapes. When mechanically or chemically bonded, these components can substitute for more expensive elastomeric compounds, retain the shape, and cut assembly costs by consolidating parts, integrating features, simplifying assembly, and reducing leaks.
  • Rubber-to-Metal Bonded Shapes. Ideal for applications that require structural rigidity, shape retention, and load carrying capacity, these seals offer the advantages of rubber or plastic bonded shapes and can be molded as complex three-dimensional configurations.

What Manufacturing Process Will Meet Your Objectives?

After the design phase, Performance Seal will manufacture your product using the most appropriate molding process for the design you have chosen, as well as your cost parameters and volume requirements. Molding processes might include:

  • Compression Molding. An economical process that offers medium precision, compression molding uses a free-form slab of metal that is placed into a tooling cavity. When the tooling plates are clamped together, the elastomer feeds into the cavity.
  • Transfer Molding. Economical for medium to high precision components, transfer molding forces material from a slab free-form secured above the tooling cavity through screws and into the cavity. This process can produce over molded components where one material is molded onto another without the need for primers or adhesives. Multiple parts can be made at one time.
  • Injection Molding. Economical for high-volume of medium to high precision components, injection molding forces a continuous strip of preformed material through a runner system and into tooling cavities. The process requires reduced cycle time, works for producing over molded components, eliminates flash, and has little waste.
  • Liquid Injection Molding. Economical for producing high-volume, high precision components, liquid injection molding pushes a two-part component into the barrel of the press and mixes it. A pump forces the elastomer to flow into the cavity, which results in specialized products, short cycle times, no flash, and the least amount of material waste.

With all processes, once the elastomer is vulcanized, the parts are removed from the tooling.
