Rubber Injection Molding

Rubber injection molding is a manufacturing process that involves injecting uncured high consistency rubber (HCR) into a mold to create precise, highly engineered products. At RD Rubber Technology Corporation, we deliver custom engineered rubber injection molding solutions to our customers.

Learn more about how rubber injection molding works, the benefits of choosing this manufacturing method, and the industries we serve.

How Rubber Injection Molding Works

First, rubber is fed into a screw that exerts heat and pressure on the elastomer material. The elastomer material is then injected into a rubber mold at high pressure so that the cavities are properly filled to exact geometric tolerances, forming the shape of the mold.

Benefits of Rubber Injection Molding

Rubber injection molding is a versatile method that can produce a wide range of precision rubber products. The manufacturing method is especially useful in creating medium to high volumes of custom-engineered rubber components. Here are several key benefits of rubber injection molding:

What is Rubber Injection Molding

  • No pre-forms: The elimination of pre-forms reduces potential variability in material weight and shape and optimizes labor requirements.
  • Faster production cycles: Rubber injection molding offers reduced cycle times compared to compression and transfer molding as the injection screw pre-heats material before forcing it into the mold cavities, which enables the material to flow more easily into the cavities.
  • Volume Production: Ideal process for medium to high volume production.
  • Rubber overmolding: Capable of producing overmolded components.
  • Environmental savings: Minimal flash and material waste

Applications of Rubber Injection Molding

Rubber injection molding is utilized to produce custom engineered products for mission-critical applications in many industries including Aerospace, Biomedical, Biopharmaceutical, Biotechnology, Chemical Manufacturing, Chemical Processing, Dairy, Defense Industry, Department of Energy (DOE), Department of Defense (DOD), Electrical, Electronics, Food Production, Food Handling, Food Processing, Food & Beverage, Genetics, Government, HVAC, Hydraulics, Industrial, Laboratory, Industrial Machinery, Medical, Medical Devices, Military

Nuclear, Pharmaceutical, and Pumps and Semiconductor markets. Some of the most common applications include: seals, O-rings, gaskets, grommets, valves, diaphragms, poppet assemblies, plungers, latches, flappers, vacuum cups, boot pads, switches, covers, shells, housings, cases, connectors, and buttons
