Custom Capabilities

While thousands of sizes of caps and plugs are stocked and ready to ship, not every application is suitable to a stock item. Many irregular shaped items require a unique mold. StockCap is the premier choice for the production of a custom molded part.

  • Design a mold utilizing numerous manufacturing processes.
