WebPro LB3500 Laser Processing System

WebPro LB3500 Laser Processing System

Cost-Effective Jumbo Roll Processing

Preco's WebPro® LB3500 series are wide web-based, traveling head laser systems for roll-to-roll or roll-to-discrete part processing. This unique system provides the capability to process wide format material with a single high speed scanner delivered laser. It is ideal for processing wide web products with low production needs. The LB3500 is available as a "drop in" laser workstation to an existing web line or turnkey with an unwind, rewind and optional 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.
