StockCap - Plastic Injection Molding, injection molding company, injection molding manufacturerInjection molded parts are often the best choice for complex, high-volume products that require tight tolerances. In fact, injection molding is the most prevalent process for creating plastic parts ranging from housewares to airplane parts, gardening equipment to toys, even automotive to cosmetics. At StockCap we specialize in manufacturing plastic injection caps and plugs.

Some of the injection molded plastic parts produced by StockCap can be used as both a cap or a plug. Some are designed with a tab for easy removal. Still, some are for threaded items. In addition to our stock line of plastic injection molded caps and plugs, we can make custom parts to fit your exact requirements.

The injection molding process involves pouring liquid plastic into a mold and letting it cool until it takes the shape of the mold. The shape of your product is used to create a mold and our engineers work with you to design the mold. Prototype testing is used to confirm a production run. The end result is a plastic injection molded part with the lowest tooling cost in the industry.


  • Economical
  • Tight tolerances
  • Minimal finishing work needed on final product
  • Quick turnaround time
