Pneumatic Dot Peen Marking Machine
Ideal for switchgear, panel and transformer factories that need permanent serial/batch traceability on copper and aluminum bars in tough environments.
Quick Summary
The LT-PM100 pneumatic dot peen marker is the right traceability tool when a Thai switchgear or transformer plant needs a mark that survives plating, coating and rough handling: an HRA92 tungsten pin indents 0.1-1.0 mm into copper or aluminium bar 5-15 mm thick at 3-5 characters per second over a 150 x 100 mm field. Because the mark is a structural indentation rather than a surface print, it stays readable after finishing. It needs only 0.3-0.6 MPa compressed air, repeats to ±0.02 mm and is built for 24/7 duty. Choose the laser marker instead when code density and cycle time dominate.

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.
Mark depth and permanence
Test condition: marking copper or aluminium bar 5-15 mm thick, then sending the part through coating or plating. Result: an adjustable indentation 0.1-1.0 mm deep made by an HRA92 tungsten pin, with ±0.02 mm repeat accuracy. Baseline: the fiber laser marker marks without removing material and publishes no depth value, so dot peen is the choice whenever the specification calls for a tactile, permanent indentation.
Marking throughput
Test condition: marking text, serial numbers, batch codes, 2D Data Matrix or QR codes over a 150 x 100 mm field (customisable). Result: 3-5 characters per second. Baseline: the fiber laser marker reaches up to 7,000 mm/s marking speed with 0.15 mm minimum characters, so high-volume dense coding goes to the laser and long-run permanence goes to dot peen.
Utilities and duty cycle
Test condition: continuous factory duty on a compressed-air supply. Result: 0.3-0.6 MPa air, 24/7 rugged construction, and integration with automatic lines and 3-in-1 machines. Baseline: the fiber laser marker covers a wider 3-15 mm bar range and needs only electricity, so it fits stations with no airline; dot peen fits stations where a physical indent is required.
Is it suitable for dusty or hot workshops?
Yes. Its construction is designed for demanding factory environments.
Will marks remain legible after coating or plating?
Yes. The mark is a structural indentation, so it stays legible even after coating or plating.
How much air does it need?
Only 0.3–0.6 MPa, with a built-in air regulator and filter.
