      The highest precision, tolerance and lowest flash in the industry.

      Our injection molding expertise includes both plastic injection and liquid silicone rubber injection molding. Operating costs of injection molding rubber may be significantly lower than other rubber molding methods, based mainly on the automation and continuously running operation. Like compression and transfer molding, liquid injection molding rubber offers a wide variety of rubber part finishes and colors.  

      Injection Molding

      We custom mold components to your specifications using buna rubber, butyl rubber, fluorosilicone, natural rubber, synthetic rubbers, silicones, plastics, TPE and high temp plastics.

      Custom compounding

      With decades of experience, our staff chemists can develop custom organic or silicone compounds to satisfy your specific requirements. Each batch is tested and approved before being sent to production. Standard tests for each batch include rheological and physical profiles. These are checked against limits set for approval or rejection of each compound. Customer required tests or tests critical to the function of the molded product, are continually monitored in our laboratory. To assure consistent properties of mixed materials, our staff chemists analyze statistically organized data collected by our software programs.

      Class 10,000 clean room

      With Hepa filtration, room pressure monitoring, airflow monitoring and constant temperature and humidity controls, our  5,000 square foot, low particulate Class 10,000 clean room for custom rubber molding meets industry demand for quality molded elastomers.
      All clean room processes involved in manufacturing your custom components are performed in our clean room, including: custom compounding for material, molding, washing, quality inspection, customer specified processing, sub-assembly and special packaging.


      Whether it’s tool prototype design, functionality testing or providing fused deposition models, machined prototypes or single cavity prototype molds, we ensure your prototype components don’t just resemble the look and feel of custom rubber or plastic parts. Our prototype tools are capable of being worked into production tools after the finalization of the design.
