PIAB’s DURAFLEX® Friction Cups feature a rough cleat surface and sharp cleat edges and channels. This design creates greater friction and a stronger hold compared to traditional traction suction cups. Normal cup abrasion resulting from handling oily sheets does not degrade the shear force performance of PIAB’s friction cups over time. The added durability of the cups extends use life for long-term reliability.

PIAB’s DURAFLEX® Friction Cups maintain their hold on heavy and slippery sheets during accelerations and de-accelerations, especially in the instance of emergency stoppages. All parts are maintained in the proper position to facilitate applications such as stamping, reducing scrapped products and improving overall line sustainability. Made of DURAFLEX® polyurethane, PIAB’s Friction Cups will not break or crack after exposure to ultraviolet light, heat or ozone, which is an issue with cups comprised of rubber compounds.

To prevent damage to the surface of thin metal sheets common in automotive and large appliance applications, PIAB’s DURAFLEX® Friction Cups feature a dual-hardness design and soft cup body. Lower vacuum force is needed to seal the cups to part surfaces for gentler handling. The soft lip of PIAB’s friction cups also molds easily to curved surfaces for less vacuum leakage and stronger grip.
The cups also maintain their elastic memory and original shape for an expanded life cycle. Installing fewer cup replacements results in costs savings and reduction in waste, helping manufacturers meet their sustainability goals. Additionally, the durability and effectiveness of PIAB’s friction cups enable manufacturers to use fewer cups if production speeds allow.

Manufacturers can choose from several models of PIAB DURAFLEX® Friction Cups. The BFF model is ideal for handling concave and convex surfaces while the FCF model offers increased stability for handling larger metal sheets. For products with narrow surfaces, PIAB also offers its friction cups in an oval shape. The cups operate between temperatures of 10º to 40º Celsius.

“Our customers are operating in a volatile economy where increasing productivity is essential for success,” said Peter Tell, Chief Technical Officer, PIAB. “Today’s manufacturers must not only accelerate the production of quality goods, they must also reduce expenses while exercising environmental awareness. At PIAB, we are dedicated to continually developing smart-engineered technology to help companies stay ahead of the curve.”
