Core Working Principle of CO₂ Laser Cutting and Engraving Machine

CO₂ lasers generate infrared laser light with a wavelength of 10.6μm (in the mid-infrared range) by electrically exciting a CO₂ gas mixture (usually containing CO₂, N₂, He, etc.). This wavelength of laser light has a very high absorption rate for non-metallic materials (such as wood, acrylic, fabric, etc.). When irradiated onto the material surface, the energy is rapidly absorbed and converted into heat, causing the material to locally melt, vaporize, or burn instantly. Combined with the movement trajectory of the laser head (controlled by a CNC system), this achieves cutting (separating materials) or engraving (surface removal or marking) effects.

High Power Leading the Future: Power Changes and Market Trends of Chinese Laser Cutting Machines

In the past decade, the power of Chinese laser cutting machines has surged from 1kW to over 100kW. Models with 12-40kW power have become the market mainstream. Breakthroughs in domestic technology have driven a sharp drop in costs. High-power equipment is reshaping the industrial cutting landscape, while trends in intelligence and environmental protection are accelerating industry upgrades.

Focusing on Innovations in Intelligent Laser Engraving Technology, the 2025 Shanghai International Wide-format Printing Exhibition Held in Shanghai

From March 4 to 7, 2025, the 2025 Shanghai International Wide Format Printing Exhibition will be held at the National Exhibition and Convention Center (Shanghai). As a benchmark exhibition in the global advertising signage and digital printing field, this event, themed "Printing Without Boundaries," gathers over 1,600 domestic and international companies to comprehensively showcase cutting-edge technologies and innovative applications across the advertising signage, digital printing, and intelligent cutting industry chains. Among them, the intelligent laser engraving machine, with its technological breakthroughs and expanded applications, has become the highlight of the 7.2H Intelligent Cutting and Engraving Pavilion.

Analysis of Key Implementation Points of RoHS Certification in Laser Engraving Machine Control Systems

With the widespread use of electronic devices and the continuous improvement of environmental awareness, RoHS certification, as a key standard for measuring the environmental compliance of electronic products, has increasingly become a focus for manufacturers of laser engraving machine control systems. The RoHS (Restriction of Hazardous Substances) directive aims to restrict the use of harmful substances such as lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers to reduce environmental pollution and harm to human health. As a high-precision optoelectronic device, the laser engraving machine's control system integrates a large number of electronic components. Therefore, strictly implementing RoHS standards during design and manufacturing is crucial to ensuring the product's market competitiveness and compliance.
