Piab HNBR Hot Surface Suction Cups Review: Specs, Price and Applications

Piab's hot surface suction cups use HNBR, a material introduced to the piGRIP line and to smaller Bellows and Universal models. HNBR offers tear and abrasion resistance for a longer life than conventional cup materials.
The cups are PWIS free, leave no marks and suit sensitive surfaces such as glass. piGRIP versions come in four sizes from 29 to 79 mm, and Bellows and Universal versions from 10 to 20 mm.
Quick Verdict
A practical upgrade for hot part handling. Picking parts earlier from the mold can shorten cycle times and save cooling energy.

Design and Operating Principle
Standard cup materials soften or wear quickly on hot parts. HNBR keeps mechanical strength at elevated temperature, so the cup can grip parts straight from the mold.
Picking earlier means the mold does not need to wait for full cooling, which shortens cycle time and reduces cooling energy.
Being silicone and PWIS free, the cups are safe for parts that will later be painted, such as automotive components.
Integration and Selection
Choose piGRIP sizes for larger parts and small bellows or universal cups for small items. Confirm temperature limits with Piab, as they are not stated on A3.
Use piGRIP's modular fittings to build cups that fit existing tools.
