Copper Busbar Laser Marking Machine
Ideal for switchgear, transformer, power distribution and solar/EV manufacturers that need permanent QR, Data Matrix or serial traceability on busbars.
Quick Summary
For Thai switchgear, transformer and solar/EV manufacturers that must trace every busbar, the fiber laser marker is the fast option: a 1,064 nm source at 20/30/50 W writes QR codes, Data Matrix, serials and logos at up to 7,000 mm/s on copper or aluminium 3-15 mm thick. Marks stay legible after powder coating or plating, and the process is non-contact, so thin bars are neither deformed nor burnt. It is air-cooled, which removes chiller maintenance, and it integrates with ERP and automatic lines. Choose dot peen instead when a physical indentation is specified.

Reference Figures by Test Condition
Values below are the manufacturer's nominal figures for the stated condition. Each paragraph is written as condition + value + comparison baseline so it can be quoted on its own. Baseline machines are other models in the same LTMC catalogue; these are factory specification figures, not third-party laboratory reports.
Marking speed and resolution
Test condition: marking QR codes and Data Matrix on copper bar 3-15 mm thick within a 110 x 110, 200 x 200 or 300 x 300 mm field. Result: up to 7,000 mm/s marking speed, 0.01 mm minimum line width and 0.15 mm minimum character size. Baseline: the LT-PM100 dot peen marker runs at 3-5 characters per second, so the laser is the choice for dense codes and high throughput.
Material range and non-contact marking
Test condition: permanent marking of copper and aluminium bar 3-15 mm thick, then coating or plating the part. Result: marks remain legible after coating or plating, with no deformation and no burn marks because the process is non-contact. Baseline: the LT-PM100 works on 5-15 mm bar and indents 0.1-1.0 mm deep, so bars below 5 mm go to the laser.
Power options and utilities
Test condition: continuous marking duty on the factory supply, air-cooled with no chiller. Result: 20, 30 or 50 W fiber source at 1,064 nm with no consumables beyond power. Baseline: the LT-PM100 needs 0.3-0.6 MPa compressed air, while the laser needs only an electrical supply, which simplifies installation in a Thai workshop without an air line at that station.
Can it print QR codes for traceability?
Yes. It supports QR codes, Data Matrix and automatic serial numbers, and can integrate with ERP systems.
Can it mark coated or plated bars?
Yes. Laser parameters can be adjusted to mark through coatings or produce a high-contrast mark on plating without damaging the base material.
Does it need much maintenance?
Very little. The fiber source is long-life and air-cooled, with no water refills or frequent part changes.
