Application

Based on 70 years of rubber expertise we have constantly refined the rubber molding process in combination with metal, plastics and even ceramics. As material and process specialists we have created engineering solutions for:


  • Electronics:  
    Plastic reinforced seals minimize designed space
  • Electro-mechanics: 
    Plastic covers integrate multiple seals and pressure expansion membranes
  • Fuel management:  
    Spring-loaded seals with metal washer replaced by rubber/plastic seals
  • Air intake: 
    Butterfly throttle seals with integrated Teflon® lubricated bearings
  • Water cooling: 
    Snap on rubber/plastics connectors

Process

Metal, plastic and ceramics can be bonded by mechanical interlock or chemical bonding agents to most rubber compounds. These processes are labor/cost intensive and environmentally volatile.


In 1994 Jäger pioneered the rubber to plastic direct injection molding process. This technology is available in La Porte, Indiana; serving the North American marketplace.


Material

Our proprietary plastic resin and rubber compounds are specially formulated to form a direct bond without any primer and adhesives. Our specific mold design and the molding process parameters complement our materials to achieve bonding forces between  rubber and plastic higher than the structural strength of the rubber matrix.

Benefits

Specific rubber and plastic materials:


  • Rubber is more cost effective than high performance TPE´s
  • Chemical resistance of rubber is better than TPE
  • Better performance with rubber versus TPE where heat resistance is concerned

Functional safety:

  • Stabile and reliable parts
  • Reduce leaking potential by over molded seals
  • Prevent loss of parts in subassemblies by part bonding

Cost savings:

  • Reduced assembly costs
  • Integrated design lowers sourcing and handling costsReduced quality costs by higher assembly process stability
