On The Fly Extrusion Line Laser Systems

Extrusion is a high-volume manufacturing process in which raw material is melted and formed into a continuous profile.

Extrusion produces items such as PVC pipe, tubing, weather-stripping, fencing, deck railings, window frames, plastic films and sheeting, thermoplastic coatings, wire insulation, and irrigation drip tape. Many of these products require high-speed and accurate direct part marking or cutting/drilling.

Challenges to Laser Processing in Extrusion Lines

CMS Laser machines are tailored to each customer’s specific requirements and therefore can be designed to most effectively meet the challenges in each particular application.

1) High-speed and constant movement.

The primary challenge of integrating a laser system into an extrusion line is that the laser machine must mark/cut/drill the parts as it is in constant motion.

CMS Laser has developed true On The Fly laser processing with closed loop feedback to process the parts as they travel past the laser field while accounting for variations in line speed. If the application requires, our machines can also incorporate camera vision systems to verify and validate the placement and quality of the marking or drilling.

2) Reliability

Extrusion lines are part of high-production manufacturing processes and often run 24 hours a day, 7 days a week. The laser system must not stop unexpectedly while the extrusion line is still in operation. Any interruption of an extrusion line comes with extremely high costs due to the non-stop raw material flow.

With many machines already in the field all around the world, CMS Laser engineers know how to develop laser processes and design machines that will be robust enough to handle continuous operation.

CMS Laser has many years of experience integrating laser processing machines onto existing extrusion lines to handle many different applications. Our Applications Development Lab will find the best laser and optics configuration to meet your needs.

Common Applications for Lasers on Extrusion Lines

Some of the most popular applications for laser processing of extruded parts include:

  • Gas Line Pipe Laser Marking
    • Direct part marking of identification information including serial numbers, part numbers, date codes, 2D matrices, and graphics.
    • Marking on industry standard yellow and black gas line pipes.
  • Low-Density Irrigation Drip Tape Laser Slitting and Laser Drilling
    • Must cut hole with specific dimension without damaging the underlying emitter.
    • Hole must be placed accurately at specific distances down tape.
