Kearns Launches 3-Axis Controlled UV Laser Marking Machine to the UK Market

Recently, Keyence announced that it has delivered the MD-U series of 3-axis controlled UV laser marking machines to its UK customers. This product technology utilizes ultraviolet lasers with high absorption rates to perform cold labeling on various materials - a process that can be carried out under minimum thermal stress.

UV laser is generated by passing a standard wavelength laser (1064nm) through a nonlinear crystal and then reducing the wavelength size to (355nm) through third harmonic generation (THG) through another crystal.

As the demand for more complex products and diverse materials increases, Keinz has developed triaxial lasers to meet the demand for higher quality and more stable results. The company stated that lasers can achieve high contrast and uniform labeling on materials that were previously difficult to label. These operations can be performed at 330 × On an area of 330 millimeters, while reducing costs and simplifying the processing process.

This 3-axis UV laser marking machine can be used to generate high contrast markings on various materials, such as plastic, glass, and other thermosensitive materials. The marking head of the MD-U includes an embedded multifunctional camera that can automatically focus on a part, check the quality of the marking, and read the 2D code. By tracking unintentional deviations in target height or tilt, it is possible to prevent marking defects throughout the entire marking area.

Kearns also stated that its maximum operating speed in standard areas is 12000 mm/s, with built-in proprietary digital scanners and different quality adjustment levels, making the laser work faster than traditional models. At the same time, pattern selection software can customize and edit materials.

Kearns has developed the aforementioned laser using its proprietary sealing method, ensuring that its components have environmentally friendly performance and are not affected by factors such as dirt, dust, and water droplets.

In fact, three-axis laser technology has potential applications in various industries, including the automotive industry - it can help develop plastic parts, cationic painted parts, and smaller parts. In the electronics industry, it can help manufacture LED lights, wafers, and more. In addition, it will be able to assist the medical industry in developing tablets, bottles, and instruments, as well as manufacturing shells for some products in the food/cosmetics industry.
