Rubber Molding

Atlantic Gasket Corporation, a leading rubber molding company, custom manufactures precision molded rubber parts for customers from a wide range of industries. We offer three rubber-molding methods including injection molding, transfer molding, and compression molding and will work with you to determine the one that will produce your custom rubber part within your budget and by your timeline.

While these methods are similar in that they all make use of heat and pressure to cure rubber parts, they differ in some significant ways. For more information read on or contact Atlantic Gasket, a rubber molding company with complete industry know-how at sales@atlanticgasket.com or 800-229-8881.

Rubber Injection Molding

In rubber injection molding, materials are loaded into a “hopper” where they are heated to the appropriate melting temperature and injected into the mold. Under clamping force, the mold halves are held together, the cavities are filled, and the mold is cooled in stages to a temperature that allows the material to solidify. Then the clamping unit is opened, the two halves of the mold are separated, and the finished product is ejected.

Advantages:
  • Best product consistency
  • Least amount of finish work
  • Best control of flash
  • Fastest cycle times
Disadvantages:
  • Most expensive molds
  • Not suited for all materials

Rubber Transfer Molding

In rubber transfer molding, un-cured rubber is placed into a portion of the mold referred to as the "pot" and the mold is closed. Once the mold is closed, hydraulic pressure on the top "plunger" plate forces the heated material through a small hole or "gate" into the cavity where it cures. When the mold plates are opened, the transfer pad (waste) is discarded and the parts removed from the lower plate.

Advantages:
  • Shorter cycles times and better product consistency than compression molding
  • Ideal for rubber-to-metal molded parts
Disadvantages:
  • The cycle time is longer and the product consistency is not as good as injection molding

Rubber Compression Molding

In rubber compression molding, materials are placed directly into the mold. The mold is closed and held under hydraulic pressure, the materials are cured, the mold is opened, and the part is removed. Excess flash must be trimmed off before the product is complete.

Advantages:
  • Least expensive molds
  • Ideal for large molded rubber parts
Disadvantages:
  • Least product consistency
  • Not suited for all rubber part designs
  • Least control of flash
