Do you need speed, cleanliness, precision, or a guarantee that no conductors will be nicked as part of the wire stripping process? Then consider laser stripping from MJM Industries.

Insulating jackets can be removed from wire and cable using many different methods. Before choosing the proper method, you must first define the requirements of your applications. Methods of stripping include abrasion, chemical, mechanical, thermal and laser. While mechanical tends to be the most
popular method, providing speed and accuracy, thermal and laser provide the best opportunity for removing difficult materials while providing no conductor damage. When choosing between the two, one should realize that thermal methods require much more process control and periodic adjustments
in order to retain quality. Thermal processes also often require secondary operations to eliminate rogue strands and ensure quality standards.

For purposes of this discussion, we will spend our time reviewing the pros and cons of laser stripping.

The most essential benefits of laser stripping are the guarantee for no damage to the wire and the
repeatable quality. With laser stripping, there are no limits to as how small a wire gauge can be stripped.

Advantages of laser stripping include the lack of conductor damage, the ability to process almost all insulation types, the ability to hold tight tolerances, the ability to strip a variety of wire forms, and variable strip patterns and the ability to process multiple wires simultaneously.

By using a laser, the insulation will absorb the beam and be vaporized.

The metallic materials of underlying wire conductor will reflect the laser beam, resulting in no damage. An alternative to standard mechanical stripping devices, our laser wire stripper is a computer-controlled machine, much like a CNC router, which uses a laser to burn off the insulation of the wire.

The system consists of a laser, an optical system, controls, application tooling and safety barriers. Laser wire stripping machines are your best choice for very fine gauge wires since they do not damage the conductor. Since laser wire stripping is a non-contact process and the laser beam can be controlled very specifically, it is possible to perform end strip via cross-cut, windows, mini windows, angled cuts and programmable patterns at any point on ribbon or wire cable.
