High-Performance Laser Stripping Machine with Compact Design



The Mercury-4 is the culmination of years of research into laser stripping of wires and cables. It has been developed in partnership with Schleuniger and optimized in every way for your production needs. It boasts an array of features:

  • Low cost / excellent ROI: for its functionality lowest cost model available - opens up a massive range of applications. No laser or machine wear parts.
  • Compact: lowest footprint model on the market - use from a sitting position with space for other tools and parts.
  • Fast: up to 80” (2000mm) per second stripping speed for fastest processing.
  • Versatile: strips single conductor, coax and ribbons; 0.0010mm2 to 16mm2 (50 AWG to 6 AWG). All insulations. With dual (X & Y) axis motion it handles all strip types: cross-cut, windows and area ablation; and any shapes: curves and hatched areas, not just straight lines.
  • Flexible: fast loading of single wires / cable via a port or use a fixture plate for complex multi-conductors or ultra-thin wires. In-line stripping operation also available.
  • Clean and precise: ​featuring double-sided galvo-scanner technology to allow nick-free stripping, with +/- 0.004” (0.102mm) repeatability for the best quality every time. In-built camera allows the whole process to be monitored.
  • Ease of use: operator selects via touchscreen the desired stripping parameters from the programmed library and all parameters (strip lengths, laser power and speed, etc) are automatically set.
  • Energy efficient: runs from a standard 115 / 230 V electrical supply with no compressed air requirement.

Application Range

Strip Types

The Mercury-4 dual axis optics allows flexible wire stripping:


From top to bottom:
  • cross cut: laser separates the slug of insulation - Operator pulls off as a second operation
  • slit: laser makes a cross cut but also slits along the insulation to aid peeling off a long length. Especially used for cable jackets
  • window: like a slit, but two cross cuts are made to allow a window section of insulation to be removed - used especially for accessing the shield of a cable for attaching to the shield
  • area ablation: the laser passes back and forth over the wire multiple times to completely vaporize an area of insulation.


All the Mercury systems are capable of stripping polymer insulations. All polymer insulations can be cut with the laser. The amount of melt, vaporization or chemical decomposition depends on the exact polymers used. Below is a non-exhaustive list of materials that can be stripped:

  • Fluoropolymers, such as PTFE, ETFE, PFA
  • Polyethylene
  • Nylons
  • Silicone
  • PVC
  • Rubber


  • Mylar
  • Fiberglass
  • Polyurethane
  • Polyester

More Info

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.
