WebPro LB4000 Laser Processing System

WebPro LB4000 Laser Processing System

Mass-Production Solution

Preco’s WebPro® LB4000 series are wide web-based laser systems for roll-to-roll or roll-to-discrete part processing. These larger, turnkey systems are ideal for high production requirements. Available in two different widths, the base systems feature reel-to-reel processing with multiple lasers. The base systems may include additional features to accommodate inbound lamination, in-line mechanical slitting, loose discs output conveyor, differential rewinding or multiple robotic stacking.

Preo Laser Technology Advantages

Lightning Bolt™ AcuVision
Registers parts before processing and aligns cut pattern to fiducials - either printed or mold marks. Inspection of part available after processing for 100% quality control.

Fast Processing Speed
Cut parts from moving webs for maximum production rates.

Soft tooling process, that is ‘flexible’
Eliminates tool and die fabrication, maintenance, and storage costs.

Laser cutting is a forceless process
Produces intricate patterns and fine details. Superior part quality that cannot be replicated using the die cut process.

Easy to use Windows® based software
Enables make-to-order processing of short-run or complex jobs.

Ramp up / Ramp down control
Eliminates scrap caused by overpowering of material at slower than normal processing speeds.
