Compression molding
GEFICCA uses compression molding to manufacture molds of all sizes and a diverse range of weights (under 1g / greater than 100 kgs). This also allows for variable hardness (20 to 90 shA) and standard or custom-made materials (EPDM, natural rubber, silicone, nytrile, butyl, polychloroprene, etc.)
How it works ?
Compression molding (direct or by transfer) requires various manual operations prior to vulcanization (cooking), such as the preparation of raw blend blanks, which are then placed in the mold cavities or in a transfer chamber prior to compression. The molding cycle time depends on the type of elastomer and the part geometry. When the vulcanization is complete, the rubber part is removed from the mold and then checked.
