To help automotive and white goods manufacturers improve production speed and eliminate bottlenecks, Piab offers its DURAFLEX Friction Cups, a line of suction cups providing the ultimate grip on oily and wet surfaces. The cups’ grip pattern enables operators to safely and reliably move slippery metal goods without slowing production lines. These friction cups from Piab let manufacturers to reduce product droppage and lower scrap rates.
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 the 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 two oval shapes. The cups operate between temperatures of 50º to 122º F.
