Molded End Details

We have built our manufacturing process on the intent that every customer’s need is unique.

Molded Details are an advanced science of molding rubber or plastic material around or conjoined to a polymer extrusion, metal or other component.

Proper tooling enables this complex process to work for tight tolerance requirements. This procedure requires the selection of compatible materials in order to achieve superior physical and chemical bonding.

Types of molding processes used: compressiontransfer.

Our highly engineered and custom molded details can enhance the functionality, performance, appearance and longevity of products as well as reduce shock and vibration, dampen sound, provide insulation, and improve chemical/UV resistance.

Compression Molding

Compression molding takes place as two plates of mold are forced together. A slightly oversized rubber preform (raw compound) is shaped to approximately fit into the mold cavity. When the plates are squeezed together, the preform is compressed and forced to conform to the mold cavity. A molding press is used to provide the necessary force to close the mold. Excess material, or flash, that squeezes out is pushed into grooves cut into the top plate and later trimmed off. Once the curing or vulcanizing process is complete, the mold is opened and the molded product can be removed.

Transfer Molding

Transfer molding can be considered a form of compression molding in that pressure forces the rubber to conform to the mold cavity. The main difference is that in transfer molding, the rubber preform is heated and forced by a plunger through a funnel-shaped opening, or sprue, into the mold cavity.
