Value-Added Services

We offer many design and manufacturing processes that can enhance the fit and functionality of your components. 

Our application engineers work with you to identify opportunities to improve part production or installation as well as increase the appeal of your products. 

No matter what stage your project is in, we can develop and refine simple or highly complex profiles. This often can lead to cost reductions or quality and performance improvements.

Extrusion With Coating

Coatings

Our various coating options can serve as an assembly aid or reduce noise, wear and abrasion. This process can be used to coat entire sheets or a localized area on each part.

Beige Window Gasket

Color Match

We offer color matching capabilities for silicone and organic compounds. For specific color requirements, please provide us with a sample or Pantone (PMS) number so we can match the color to your needs.

Cutting Machine

Cutting Processes

We can finish products with a variety of cutting processes including: cut to length, punching, die-cutting, notching, drilling, kiss-cutting, slitting and custom cutting. In some cases, these finishing processes can be good alternatives to rubber molding.

Drilling Machine

Drilling & Punching

Seals may require vent holes that enable the part to collapse under pressure. During part extrusion, holes can be drilled at precise, uniform intervals. Cut-to-length parts also can be placed in a punch press where a die creates the intended feature.

Flocked Extrusions

Flocking

Flocking is a velour-textured material that can be applied to many polymers and dyed to match virtually any color. Flocked surfaces help reduce friction and water absorption while dampening vibration and offering thermal insulation.

ID Printing Machine

Identification Printing

Identification marks on products can be crucial to manufacturing efficiency and quality. From an intricate logo to customer part numbers, we can provide identification markings that best fit your requirements.

Lamination Process

Lamination

Lamination (tape) can often eliminate mechanical fastening systems (staples, nails or retaining clips) and their inherent challenges. Many different heat-activated and pressure-sensitive adhesives are available to meet your requirements.

Custom Packaging Equipment

Packaging

In addition to designing materials and profiles, we can specify and order your private label packaging to provide a complete product solution.

Push-Pin Extrusion

Push-Pin Seals

These seals provide an alternative to standard laminated seal methods with pins that are spaced according to your requirements.

Gasket Splicing Equipment

Splicing

Splicing can be used to form a simple O-ring or a complex multi-side product. We offer cold and hot splicing as well as transfer molded joints and vulcanized corners.

Multiple-Durometer Extrusions

Multiple-durometer products combine two or more materials through a single die with the cavities arranged so that the extrusions merge and weld together into one structure.

Cooper Standard ISG creates multiple-durometer extrusions from polymers such as EPDM, silicone and plastics.

Most often, the harder material serves as means of attachment and the softer compound completes the seal. Sometimes, however, coextruding polymers can serve cosmetic purposes.

Material Considerations

Developing the appropriate material compound for an application requires the consideration of several factors.

Each material has its own advantages and disadvantages. Typically, the best course of action is to select a material that achieves a balance of performance properties while remaining cost-effective.

Aesthetics, pricing, rigidity, compression set and ease of extrusion are among the factors engineers consider when deciding between materials.

Understanding your application environment allows us to ensure your seal or gasket performs to expectations.

Silicone Rubber

 

Rubber vs Plastic

Rubber and plastic can have many overlapping performance properties.

Several closed-cell sponge and dense thermoset (rubber) materials may be evaluated based on the criteria of your application. These include:

  • EPDM - Ethylene Propylene Diene Monomer
  • VMQ - Silicone
  • CR - Chloroprene/Neoprene
  • NBR - Nitrile
  • NR - Natural Rubber
  • PUR - Polyurethane 
  • FKM - Fluoroelastomer
  • FVMQ - Fluorosilicone

 

Cooper Standard’s plastic capabilities cover a variety of materials and industry specifications across many markets. Our plastic materials include:

  • TPE, TPV, TPU - Thermoplastic Elastomer 
  • HIPS - High Impact Polystyrene
  • ABS - Acrylonitrile Butadiene Styrene
  • PE - Polyethylene 
  • PA - Nylon/Polyamide  
  • PVC - Polyvinyl Chloride (Rigid & Flexible)
  • ASA - Acrylonitrile Styrene Acrylate  
  • EPP - Expanded Polypropylene 
  • PP - Polypropylene

UL Gasket Materials

Cooper Standard ISG offers a variety of UL-approved materials for HVAC, lighting, window and door, appliances and other critical applications.

By using a UL-listed compound for seals and gaskets, manufacturers can reduce the costs of testing needed to obtain UL certification for their end-product.

Our seal and gasket material capabilities include the UL-555S standard for smoke dampers, UL-10B and UL-10C listing for fire-rated doors, UL 157 and UL 94 (V-O, V-1, & HB).

Whether it’s a simple or sophisticated part, our engineering team can develop a product that meets just about any commercial or industrial specification.
