The Laser Wire Solutions Mercury-4 strips wires and shielded cable ranging in size from 0.025 – 6 mm OD (0.001" – 0.24"). The laser is strongly absorbed by the wire/cable insulation causing it to melt or vaporize. By stripping from both sides automatically a slug of insulation can be separated from the main wire/cable insulation. The slug can be left on to keep the wire strands together, only being pulled off by the Operator immediately before termination. The Mercury-4 also allows the possibility to fully vaporize the wire insulation by passing the laser spot over the wire multiple times at high speed in a hatch pattern. This may not be suitable for all materials - but for bonded insulations it can be the best method for insulation removal. The laser light fully reflects from the wire conductor ensuring there can never be nicks or scrapes. In the case of shielded cables, the laser can be used to cut off the jacket, the laser light reflecting from the shield or aluminized foil. The shield needs to be reasonably complete (>80% coverage) in order to protect the inner wire insulation.
The main applications are difficult to process insulations and wires where a mechanical blade could cause damage. Examples include removing the jackets from shielded multiconductor cables, removing the jackets and dielectrics from high performance microwave cables, cutting the aluminized mylar foils of twin-ax cables or removal of bonded insulations.
For standard stripping - the simple touchscreen interface allows a strip pattern (laser power, speed and position) to be set up with a few clicks. There is no need to program individual laser moves. For the most complex strip patterns (curves, circles, text etc) - the on board graphical user interface can be used to create a specific strip pattern. All patterns are saved on the system with a unique ID.
Mercury-4 begins the stripping process when the Operator starts the process via the touchscreen or optional footswitch.
For most applications - the wire/cable is introduced through a single port, pushing the cable to a reference back stop. The strip position is programmed as part of the strip pattern. For more complex cables (e.g. multiple inner wires of a multi-conductor), the machine can be instantly reconfigured to use a mini-fixture plate that can be designed for your exact cable. This allows multiple wires to be stripped simultaneously and Mercury-4's non-linear stripping (curves) allow the strip to follow the fanned shape of inner wires if required.
