The Molding Process

PPI, Protoplast Inc., has always been involved in the molding process, from its early days of prototype molding it was apparent that a high level of expertise was necessary to fulfill the customers' satisfaction PPI has that high level has been surpassed.

Injection molding success led to mastering the blow molding process and the challenges of overmolding have been conquered by the skilled workforce at PPI, Protoplast.

Our molding successes have been in three areas:

Injection molding....Injection molding takes many forms with great complexity. Vertical and horizontal molds, automatic sprue handling, multi-cavity molds, all of these are of second nature to the artisans at PPI. They have done it all, and are good at it.

Overmolding processes....Overmolding is the process of molding plastic over existing components to create the strength and flexibility one layer plastic does not possess. PPI has great success in achieving low cost high production overmolding processes.

Blow molding....is the process of injecting plastic into a mold and filling the mold cavities by pressurizing the plastic with air to form the part. PPI, Protoplast are masters of this process.
