- Grippers with all-round elastomer coating
- HNBR (Hydrogenated Nitrile Butadiene Rubber) leaves no markings behind
A few years ago, FIPA was the first company to offer sprue grippers coated with HNBR (Hydrogenated Nitrile Butadiene Rubber) on the inside of the gripper jaws. With the new grippers of the 100 series, FIPA is going one step further: All four sides of the gripper jaws are now completely coated with HNBR. As a result, workpieces can be gently handled. Upon placing the gripper on the workpiece, the HNBR-gummed jaws prevent the surface of parts from being scratched by the gripper.
HNBR leaves no markings behind
Especially in the case of complex-shaped parts with cavities and curvatures near the sprue, the scrap rate can be reduced, because no damage occurs as a result of accidental contact between the gripper and the item to be handled. As an elastomer containing no paint-wetting impairment substances, HNBR leaves no markings behind that could prevent painting or coating of the plastic parts from being carried out at a subsequent point.
High closing force ensures secure gripping
Further features include high closing force to ensure secure gripping, wide-opening gripper jaws to secure handling of large workpieces and the complete closure of the jaws to secure grip on thin parts.
