Traditional desktop laser marking machines require workpieces to be transported to the equipment station, which creates major limitations for large‑size components, heavy‑duty parts and outdoor field operations. Breaking the constraints of conventional equipment, the LZY portable hand‑held laser marking machine integrates lightweight design, intelligent touch‑screen OS and safety‑protection structures. It works offline with batteries and requires no PC, delivering a brand‑new solution for traceability marking on large workpieces.

1. Lightweight Hardware Design: Portability Meets Industrial‑Grade Performance

The LZY hand‑held laser marking machine adopts a carry‑case form factor. The marking gun weighs less than 0.9 kg for effortless single‑hand operation.

Available power ranges from 20 W to 60 W, with up to 100 W for the MOPA version. It supports dual power supply: AC adapter and swappable 15 000 mAh large‑capacity lithium‑ion battery. Charge‑while‑use is enabled for continuous outdoor operation without mains power, free from power‑cord restrictions.

Three field‑lens marking ranges are optional: 50×50 mm, 100×100 mm and 150×150 mm, covering fine small‑part marking, standard‑component marking and large‑structure marking requirements.

Full‑air‑cooling eliminates water‑cooling units, enabling stable operation in complex workshop and construction‑site environments from 0 ℃ to 40 ℃.

The marking gun is fitted with a CE‑certified full‑enclosed safety focusing hood with built‑in dust‑extraction cooling fan and viewing window to mitigate laser radiation risks and comply with EU safety standards. Multiple safety warning labels are placed on the unit to standardize operator workflows.

2. Self‑Developed Linux Touch‑Screen System: No External PC Required

Unlike many competing hand‑held marking devices that rely on external computers, LZY runs its self‑developed Linux system with a 7‑inch high‑definition capacitive touch screen. All editing and marking functions are completed on‑board with no extra computer.

✅ Supports import of texts, barcodes, QR codes, bitmaps, SVG vector graphics and DXF files

✅ Multi‑level user permission management & auto‑sleep mode to extend battery life

✅ Open API for integration with MES, ERP and PLC systems for automated production‑line deployment

✅ Compatible with external scanners, mice & keyboards; Wi‑Fi / Bluetooth connectivity; remote control via mobile APP

✅ Built‑in red‑light preview alignment. One‑click control for preview, marking and stop. New operators get productive with minimal training.

3. Versatile Marking Capabilities for Multi‑Industry Materials

Permanent, corrosion‑resistant and wear‑resistant marks can be applied onto metals, plastics, jade, leather, gears and hardware components. Typical applications include serial numbers, batch‑traceability QR codes, LOGOs and production‑date engraving. Variable text, serial‑number auto‑increment and auto‑date‑time generation are supported to satisfy factory one‑item‑one‑code traceability workflows.

Compared with the previous‑generation model, max power is upgraded to 60 W for faster marking speed and superior precision. Gun‑head safety protection is fully enhanced, and robot‑arm integration is available for automated marking tasks.

4. Comprehensive Safety & After‑Sales Support

The machine complies with GB7247 laser‑product safety standards and undergoes full‑range factory testing. Complete documentation covers safety guidelines, operation manuals and troubleshooting references.

LZY  Technology Co., Ltd holds ISO9001 quality‑management‑system certification. Services include full‑unit warranty, technical assistance and factory‑return repair, delivering stable and reliable laser‑marking solutions for industrial clients.
