P-Bas® Bonding (Diffusion Bonding)
P-Bas® (Punch-bonding and sintering) is a technology we developed to join separated materials using the Punch Group's metal processing expertise.
Benefits
Complex-shaped mold components that previously required metal 3D printers can now be manufactured through metal machining.
Utilizing our long-cultivated expertise in mold component processing, we can deliver components with complex internal features, including cooling channels, exactly as specified in the customer's drawings.
We offer an end-to-end solution, covering everything from material procurement to heat treatment and other processing to produce a finished product.
P-Bas®--a metal bonding technology that boosts productivity
P-Bas® enables the production of complex mold components with internal cooling channels, replacing metal 3D printers. This contributes to higher productivity for our customers. P-Bas® also helps reduce setup time and labor during changeovers by allowing for more flexible bolt hole placement, as it eliminates the design and machining constraints typically associated with drilling holes for cooling channels.
P-Bas® offers additional benefits, which include enhanced product quality through optimized cooling channel design and reduced product defects by using a split banana gate that opens and closes.
Key Features of P-Bas® Bonding
Production of mold components with optimized cooling channels
P-Bas® is a solid-state bonding technology that joins metal materials without melting them.
It enables the production of mold components with freely designed internal shapes that were previously only possible with 3D printers, thereby offering high cooling efficiency.
High Bonding Strength
The strength of the bonded joint retains more than 90% of the base material's strength.
It supports a wide range of materials commonly used in injection molds and die-casting dies, including SKH51, SKD61, and SUS420J2.
Rust Prevention Inside Cooling Channels
Because P-Bas® produces a finely finished cooling channel surface, impurities are less likely to accumulate, thereby suppressing corrosion inside the channels. Our patented technology applies a protective coating to the inside of the cooling channels, further enhancing rust resistance.
