Ring and Iron Ring Crimping Machines

Ring terminals and iron rings are crimped by deforming a closed or nearly closed ring around a conductor or through a fastening point, which is a different tooling problem from an open-barrel terminal: the ring must close without cracking and without cutting into the strands. This family also covers the cast-iron mute-terminal presses used where a press running all shift has to meet a noise limit on the shop floor — a requirement that appears in the specification more often than machine datasheets acknowledge. The sizing pair is the ring or terminal material and size, and the wire gauge. Terminal samples are crimped and sectioned before the order is confirmed.
