Extensive Capabilities, Exacting Standards

Since 1949, we have manufactured products for the exceedingly stringent medical and healthcare markets. Our experience enables exceptional tight tolerance precision molding, utilizing a variety of engineering resins and other thermoplastics. We can match a customer’s product development and ramp-up profile by going from prototype tooling to bridge tooling to high-cavitation production tooling. Our platform of in-house molding technologies include the following:

  • Injection molding (housing molds with up to 128 cavities)
    • Single-shot molding
    • Multi-shot molding
    • Overmolding
    • Insert molding
    • Stack molding
    • Thin-wall molding
    • In-mold labeling
  • Injection blow molding
  • Extrusion blow molding
  • Injection stretch blow molding

True Scientific Molding Principles

We develop all our processes utilizing the latest advances in scientific molding principles for unsurpassed process repeatability, resulting in part-to-part consistency that exceeds our customers’ requirements. Our decoupled molding processes achieve long-term stability that outperforms conventional process techniques.

Our cavity pressure monitoring, using the RJG eDart® system, controls and stabilizes production to ensure only the highest quality, most accurate products are manufactured. With RJG eDart® installed on every injection-molding machine, we consistently deliver at a higher level of performance.
