Molded Rubber Form for Spark Plug Casting


  • Rubber Form for Spark Plug Casting Ref: 105650, 105767

    Supplier Stability is Critical
    Our customer came to Custom Rubber Corp. out of concern for the viability of their previous vendor. They had been successfully doing business for a long time with their previous vendor, but had reached a point where their business was a significant portion of the previous vendor's overall portfolio. Custom Rubber Corp. offered a stable organization with plenty of resources available.

    The product in question is a series of rubber forms or rubber molds that are used to cast ceramic for spark plugs. The plugs in question are specialty plugs for trains, heavy trucks, and high performance automobiles. The rubber forms/rubber molds are filled with ceramic powder and then squeezed by up to 8,000 psi of hydraulic pressure to press the ceramic into the final shape.

  • Challenges to Overcome
    The first challenge was to develop a rubber formula that was as robust and durable as their previous supplier's. This took a series of trials but Custom Rubber Corp., by working with a few of their strategic partners simultaneously, was able to identify the best, most cost-effective formula very quickly. This was an instance of Custom Rubber Corp.'s ability to tap into a cadre of chemists (from multiple supplier partners) to expedite the development of a formula.

    The other challenge associated with this business is the wide range of ceramic forms that have to be produced. Custom Rubber Corp. developed a tooling scheme that allows us to use the same mold base to shape the exterior of the rubber forms, while accepting more then 10 different ID core systems to make 10 different rubber forms/rubber molds.

    Easy to Work With
    We have also setup a simplistic pricing schedule that works for both companies and addresses the wide range in rubber form/rubber mold demand - some are only 100 pieces per year, some rubber forms/rubber molds are 1,500 per month.
