R&D Molders, Inc. | The leader in custom injection and blow molding Since 1974

Injection Molding

Since the expansion of plastics into fabrication processes worldwide, injection molding has found endless popularity as a reliable approach to manufacturing. Used in making everything from simple disposable goods to complex automotive parts, injection molding’s flexibility and cost-effective qualities makes it worthy of consideration in just about any project.

At R&D Molders, Inc. we are experts at injection molding with 40 years of experience. ISO 9001:2008 compliant and lean manufacturing specialists, we are able to mold assembly parts, small to medium parts, and multi-component products out of many polymers. In addition, our automated robotic production allows for fast output and excellent quality.

Materials we work with include common polymers such as ABS, polypropylene, polystyrene, polycarbonate, acrylic, nylon, and urethane, as well as high strength engineered polymers. Our injection molding equipment is capable of 55 to 300 tons of force with 2 to 32 oz. shot sizes. Up to 16 cavities are possible, and tolerances can be as tight at ±0.003". We are also able to integrate overmolding and inserts into our injection process.

Although lead times vary on a job-by-job basis, we generally take 8 weeks to complete orders. Rush services and emergency response services are also available. We welcome orders of any volume and are open to short or long term contract runs. We are more than just a plastics molder: we can bundle value-added services with any order, such as moldmaking, inspection, machining, tooling, clean room molding, bar coding, leak testing, and many others.
