Molding Processes

The custom molding processes offered by Technical Specialties Company, Inc. include compression, transfer and injection molding.

• Compression Molding – With the compression molding process, the raw material is placed between two molded plates. Then plates are forced together, the material compresses and both heat and pressure cause it to conform to the cavities in the plates. Finally, any excess material is trimmed and the part cures. This method is often utilized when medium precision is required.

• Transfer Molding – With the transfer molding process, the raw material is inserted via a preform transfer pot into the mold cavity.  The preform rubber is heated, forced into a funnel shaped opening down into the mold cavity with a plunger, where it cures and is eventually ejected from the mold. This method is used for medium to high precision parts or instances when colored molded parts are needed.

• Injection Molding – During the injection molding process, the raw material is heated and fed into the mold cavity via an injection nozzle. The rubber cures, and the molded part is then ejected from the mold. This method is ideal when a large volume of medium to high precision parts is needed.
