It becomes possible to shape the thick parts that bear the strength to coexist with the thin parts.
PFP (Partial Frame Process) molding is an innovative molding method that enhances the rigidity and strength of molded products by incorporating a frame structure made of thick ribs at any position of the molded product, which can prevent sink marks on the surface.

basic information
◇Principle of PFP Molding Method The volume shrinkage force generated during the cooling and solidification of the resin is absorbed by intentionally growing cavities (voids)*1. ↓ This results in molded products with excellent surface properties and high rigidity. *1 These cavities (voids) can be freely created in positions that avoid affecting product strength, and they do not impact surface properties. Additionally, complex pressure-holding operations during molding are unnecessary, contributing to the stability of the quality of the molded products.

Applications/Examples of results
◇Features of PFP Molding Method - High rigidity and high strength molded products are possible with a free rib structure. - Low-pressure molding is possible without the need for complex pressure-holding processes. - Does not require special equipment, molding machines, or molds (Note). (Note) A simple shrinkage prevention mechanism is provided in the mold, but the basic structure is the same as that of a standard injection molding mold.
