Understanding the technical specifications of Dongu Laser's ring laser marking machine is essential for businesses to select the right configuration for their specific needs. The machine is available with multiple laser power options, including 20W, 30W, and 50W fiber laser sources, allowing customers to choose the power level that matches their marking requirements and material types. The 20W option is ideal for fine engraving on delicate jewelry and thin metal parts where minimal heat impact is critical, while the 50W variant provides faster marking speeds and deeper engraving capability for tougher materials. All power variants deliver an exceptionally consistent output, ensuring that marks remain uniform across large production batches. The marking speed of the machine reaches up to 10,000 mm per second, depending on the material and the complexity of the design, making it one of the fastest systems in its class. The positioning accuracy is remarkably high, with repeatability down to ±0.002 mm, which guarantees that every mark appears exactly where it is intended. In terms of compatible materials, the machine handles stainless steel, gold, silver, titanium, aluminum, brass, copper, and various coated metals with outstanding results. This broad material compatibility makes the machine a valuable addition to any production facility that works with diverse metal alloys.
