Technical FAQs
Engineering Guidance for Overseas Procurement
Common questions answered by our UK application engineers to support machine selection and sample validation.
Why choose UV laser over thermal lasers for plastic engraving?
UV lasers operate at a 355nm wavelength delivering photo-chemical 'cold processing'. Instead of burning or thermal melting, UV light breaks polymer molecular bonds directly. This results in ultra-sharp, dark or white marks with zero structural deformation, micro-cracking, or charring on sensitive plastics.
How do MOPA fiber lasers prevent melting on ABS and Polycarbonate?
Standard fiber lasers feature fixed high energy pulses that melt soft polymers. Lotus MOPA fiber laser sources feature 17 selectable pulse waveforms (from 4ns to 200ns). Shorter pulse widths minimize heat dissipation, producing clear contrast marks without melting the substrate surface.
Can international buyers sample test parts before purchasing?
Yes. Overseas manufacturers and OEMs can send sample plastic components directly to our Basildon HQ. Our applications specialists will test multiple laser sources, lenses, and settings to optimize contrast and cycle speed before providing a full technical report.
Are Lotus plastic laser marking machines compliant with global standards?
All Lotus laser systems are CE compliant, manufactured under ISO 9001 Quality Management standards, and feature full Class 2 laser safety enclosures for operator protection in high-volume production plants.
