RFH-D9-355-5W UV Laser:Plastic Shell Marking Solution
Dec 18 , 2025
1. Core Application Introduction
UV laser is a high-precision marking solution tailored for plastic shell processing, leveraging its ultraviolet wavelength (typically 355nm) to realize non-contact, pollution-free, and fine marking on various plastic materials. It avoids material deformation, discoloration, or damage caused by heat, perfectly meeting the strict requirements of plastic shell surface marking in electronics, home appliances, automotive, and consumer goods industries.
2. Key Application Scenarios & Functions
• Electronics Industry: Marking brand logos, model numbers, serial numbers (SN), QR codes, and production dates on plastic shells of mobile phones, tablets, chargers, routers, and electronic components. The marking is wear-resistant, anti-counterfeiting, and compatible with small-size, high-density marking demands.
• Home Appliance Industry: Engraving product information, safety warnings, operation guidelines, and brand signs on plastic shells of refrigerators, washing machines, air conditioners, small kitchen appliances (kettles, rice cookers), etc., ensuring clear identification and long-term durability.
• Automotive Industry: Marking part numbers, batch codes, quality inspection labels, and anti-counterfeiting codes on plastic shells of automotive interior parts (dashboard covers, door panels), exterior accessories (light shells, mirror shells), and auto electronic components, adapting to automotive industry’s high-standard quality traceability needs.
• Consumer Goods Industry: Customizing personalized patterns, brand logos, and anti-counterfeiting marks on plastic shells of toys, cosmetics bottles, daily necessities (water cups, storage boxes), and medical devices (plastic instrument shells), enhancing product brand recognition and anti-counterfeiting performance.
• Medical Industry: Marking medical device model, production batch, expiration date, and compliance certifications on high-temperature resistant, food-grade plastic shells (such as medical syringes, instrument casings), meeting medical industry’s hygiene and traceability regulations.
3. Core Advantages for Plastic Shell Marking
1. High Precision & Fine Effect: Ultra-small spot size achieves micro-marking (minimum line width up to 0.01mm), clear text/pattern edges, no burrs, and consistent color, improving product appearance grade.
2. Non-Damaging to Materials: Cold processing technology minimizes heat-affected zone (HAZ), avoiding plastic deformation, cracking, or chemical change, suitable for heat-sensitive plastics (e.g., PP, PE, ABS, PC, PVC, TPU).
3. Fast Speed & High Efficiency: High marking speed matches mass production lines, supporting continuous online marking, reducing production cycle and improving processing efficiency.
4. Eco-Friendly & Durable: No need for ink, solvents, or consumables, zero pollution emissions; marking has excellent wear resistance, corrosion resistance, and scratch resistance, not easy to fade or fall off.
5. Strong Material Compatibility: Adaptable to various plastic types (transparent, colored, soft, hard plastics), and can realize different marking effects (white marking on black plastic, color contrast marking, transparent marking).
