Punch Industry USA Inc.  is exhibiting its parent company’s bonding and sintering technology called P-Bas. P-Bas, an alternative to 3D metal printing, is used to fabricate custom conformal cooling channels for mold and die components by bonding split parts, offering an extensive compatibility with iron-based materials. Punch Industry has applied for a patent for this novel technology.

P-Bas, denoting Punch Bonding and Sintering, employs heat and pressure for metal bonding, achieving joint strength surpassing 90% of the base material. Additionally, P-Bas produces parts and cooling lines with a finer, smoother surface finish than that of 3D metal printed parts; the process includes a surface coating to reduce rust formation in the cooling lines. 

Parts that can be made using P-Bas include gate inserts for components to make plastic bottles, core pins for injection and die-cast molds, and sprues.

Customers can initiate the P-Bas ordering process by designing components with cooling channels, approving suggested split parts and receiving a quotation. Rigorous testing, encompassing bend tests for joint strength and leak tests for watertight integrity ensures the reliability of P-Bas technology.
