This rechargeable handheld laser marking machine is equipped with intelligent distance sensing and a safety guard. Powered by a wireless lithium-ion battery, it eliminates the need for power cords. Compact and lightweight, it can be easily operated by a single person. The distance-sensing feature automatically adjusts the marking distance to prevent blurred engravings caused by focal length deviations. The included protective cover effectively blocks laser scattering, significantly enhancing on-site safety, and makes the device suitable for flexible use in various scenarios, including workshops and outdoor on-site marking.

The device can produce permanent, clear markings on a variety of surfaces, including stainless steel, iron, aluminum alloy, plastic, and hardware components. The markings are scratch-resistant and fade-proof, making them ideal for applications such as part numbering, hardware logos, product traceability codes, and custom engraving. Compared to traditional plug-in handheld marking devices, this model offers superior battery life and portability, free from power outlet constraints, making it ideal for processing small-batch orders and on-site marking services.

The unit features an internal heat dissipation channel design, ensuring it remains cool even during prolonged continuous operation. It operates stably with a low failure rate and is easy to use, requiring no complex setup. Both small and medium-sized enterprises and processing shops can quickly deploy it for mass production.
