Focus: Insert Molding

Summary: In general, the term insert molding refers to the plastic encapsulation of a pre-fabricated component. The component is typically metal but could be made from some other material. The purpose of the encapsulation is to provide protection to or insulation of parts of the component. For example, semiconductor chips are partially encapsulated to protect the delicate circuitry yet leave connectors exposed.

At Plasticorp, our Cincinnatti Milacron 90 Ton Rotary Press equipped with a vision inspection system has proven itself to be an excellent machine for producing the highest quality insert molded parts while minimizing the costs of this relatively expensive process.

The unique design of the rotary press eliminates much of the ineffeciency that normally occurs when running an insert molding job. First, the operator no longer has to pause the press while placing an insert in the cavity. Second the insert is placed horizontally in the mold rather than vertically. This helps insure that the insert is place correctly and that no damage to the mold will occur. Finally, as a added measure of security against mold damage, the visual inspection system will not allow the press clamp to close if it detects any kind of inconsistancy with the mold or insert.
