Capabilities
Transfer Molding
Bruckman Rubber Co. has two transfer presses, each capable of applying 150T of pressure on platens 20” square. We also use a wide array of transfer molds on our compression presses.
Transfer Molding Basics
Transfer molding is similar to injection molding in that it uses pressure to force rubber through feeders, and then into the cavity that forms the rubber part. The main difference is that instead of using an injection cylinder, transfer molding uses a ‘pot and force’ technique, or when using a transfer press, a ‘pot and ram’ process. The material must still be carefully weighed and shaped to fit the pot.
Advantages
Transfer molding offers shorter cycle times compared to traditional compression molding and supports high precision molding applications.
Disadvantages
Material wastage can be higher with transfer molding because of the pot system, and tooling costs are typically higher compared to compression molds.
