Suction Cup for Removing Injection Molding Parts

Process reliability was low for Tanne Kunststofftechnik when manufacturing injection molding parts for vehicle interiors. The cause was identified as the suction cups, which did not develop the necessary suction force when removing the injection molding part from the mold undercut. The grained surfaces of the injection molding parts caused micro-leakage and significantly reduced the suction force. The Tanne team was looking for an alternative cup that could reliably grip grained and sometimes curved injection molding parts without loss of suction. Tanne Kunststofftechnik was looking for a partner who would provide a one-stop-shop solution in a reliable, timely and cost effective manner.

"FIPA's Varioflex suction cups proved to be the perfect solution to meet the requirements at Tanne Kunststofftechnik," said a FIPA spokesperson. "A soft sealing lip (30° shore) sits seamlessly on dimensionally stable bellows (60° shore), which prevent lateral bending. The flexible sealing lip offers a high holding force, even on uneven surfaces - a benefit that is particularly useful for grained surfaces. Micro-leakage is minimized as the bellows balance out height differences in the components. The dimensionally stable body offers enhanced reset force and enables fast cycle times."

FIPA's gripper line features products from simple suction cups and vacuum generation to customized handling systems.
