LQ-UV Laser Marking Machine

UV laser marking machine is developed by 355nm UV laser. Compared with infrared laser, the machine uses a three-step cavity frequency doubling technology, 355 UV light focusing spot is very small, which can greatly reduce the mechanical deformation of the material and the processing heat effect is small.

The UV Laser Marking Machine is a high-precision tool that utilizes ultraviolet laser technology to mark a wide range of materials, including plastics, glass, ceramics, metals, and even delicate materials like silicon and sapphire. It operates at a shorter wavelength (typically 355nm), which allows for “cold marking,” reducing the risk of thermal damage to the material. This makes it ideal for applications requiring high-quality, detailed markings with minimal impact on the material's surface.

This machine is commonly used in industries such as electronics, pharmaceuticals, automotive, and medical devices. It’s particularly suited for applications that demand high clarity and contrast, such as marking microchips, circuit boards, and pharmaceutical packaging. The UV laser's ability to produce fine, high-resolution marks makes it essential for small text, QR codes, bar codes, and intricate logos.

The UV Laser Marking Machine is user-friendly and supports integration with most design and production software. Its low-maintenance operation and high efficiency ensure consistent, reliable performance. The machine’s compact design and precision make it a versatile choice for businesses looking to achieve detailed, permanent markings on a variety of materials while maintaining product integrity.
