Summary

 Compression molding is the oldest and simplest way to make rubber products. This method take longer to  cure the rubber and each slug of rubber is often hand loaded into each cavity. However, due to the simplicity  of the mold, it is the most economical mold to buy.

 We have experiences in manufacturing rubber products for international customers. Most recently, we made  windshield wipers in EPDM and Natural Rubber. We also made rubber window seals for a Tier 1 auto parts  supplier in Canada.

Process
  1. First, open the mould and put. A precut or shaped "slug " of uncured rubber, at a set weight, is placed into the cavity.
  2. Close the mould and place back into the press, then heat and cure the rubber .
  3. After cooling, open the mould and remove the rubber parts.
  4. The excess rubber, called flash, needs to be trimmed off the part.
