Fipa Inc.’s 100 Series includes sprue grippers that feature high closing force, wide openings and gap-free, elastomer-coated jaws, enabling gentle but reliable handling of workpieces. Well-suited for removing both large and thin pieces from injection molding machines, the grippers are made of high-strength anodized aluminum alloy and the jaws are completely coated with hydrogenated nitrile butadiene rubber (HNBR). According to the company, this coating prevents even delicate materials from scratching and does not leave behind marks that could prevent successful painting or coating of plastic parts that they grip.

Intended for use in filtered, and oiled or unoiled air, the single-acting 100 Series grippers offer a 10-mm clamping diameter, operating pressure of 250 to 800 kPa (2.5 to 8 bar) and closing force at 600 kPa (6 bar) of 22 N. Other grippers in the 100 Series include medium-sized devices for adapting to customized, interchangeable jaws; grippers with HNBR-padded inner jaws; and grippers with and without sensors.
