Transfer Molding Process

Transfer Rubber Molding Process

Transfer molding consists of a mold cavity similar to a compression mold. In addition, the transfer mold contains a transfer pot and a ram, where the rubber material is placed before compression. The mold cavity contains transfer holes, which connect to the transfer pot through sprues. During transfer molding, the ram is compressed and compounded rubber material flows through the sprues into the transfer mold cavity where under heat and pressure the rubber compound cures into the mold cavity configuration.

The Da/Pro Difference

Similar to compression molding, the proprietary Da/Pro transfer rubber molding process monitors all variables and compensates for differences during each cycle. After the elastomer is cured properly, the mold cavity is opened, the part is removed, the sprue is removed, the transfer pot and mold cavity are cleaned and the cycle repeated. Our unique transfer rubber molding process allows for repeatability throughout the molding process of tight tolerance parts that are virtually flash free.
