It becomes possible to form a thick section that bears strength to coexist with a thin section.
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 generated 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 molded product's quality.

Applications/Examples of results
◇Characteristics 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 holding pressure 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.
