Varioflex suction cup improves process reliability when removing injection molding parts from molds
Even though they have only just been launched onto the market, our new Varioflex suction cups are already being used by Tanne Kunststofftechnik, a long-standing supplier to the automobile industry.High process reliability required, FIPA Varioflex suction cups found to be good: Process reliability was too low 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 cause micro-leakage and significantly reduce the suction force of standard suction cups. Vacuum cups were sought that could reliably grip grained and sometimes curved injection molding parts without loss of suction.
A case for the FIPA Varioflex suction cup: The design of the Varioflex suction cups proved to be the perfect solution to meet the requirements at Tanne Kunststofftechnik. A very soft sealing lip (30° Shore) sits seamlessly onto dimensionally stable bellows (60° Shore), which prevent lateral bending within wide limits.The highly flexible sealing lip offers a high holding force, even on uneven surfaces – a benefit that is particularly useful for grained surfaces.
Micro-leakage due to grained surfaces and curves is minimized. The bellows balance out height differences in components. The dimensionally stable body offers outstanding reset force and enables fast cycle times.Everything from a one-stop shop A further reason for choosing FIPA lies in the purchasing policy at Tanne Kunststofftechnik. Preference is given to suppliers who offer everything from one source in their segment and have proven that they supply reliable, high-quality products within a short space of time and at favorable prices. FIPA was still able to impress, even when faced with these requirements, as the FIPA gripper line extends from simple suction cups together with vacuum generation through to customized handling systems.
