Phosphor bronze 'brush contact' an integral part in electric motors for automotive rear wiper assemblies.
Following prolonged use, the domed form area of this component was prone to splitting. We enhanced the customers original design using a bespoke formed rivet as a contact face. This vastly improved longevity and prevented failure. Cost was a factor thus preventing further operations. Our answer, the flexible, efficient 'multi-slide' press.
Tooling was engineered allowing the contact to be cut and formed allowing copper rivets to be 'bowl fed' to a precision forming die. Rivets were inserted, their backs swaged, optimizing adhesion to the brush contact. The products life was extended a hundred fold.
