The principle of the food laser coding machine is that laser coding has no thermal effect on the object being marked, does not cause deformation, and compared to mechanical impact marking machines,the food laser coding machineexerts no force on the parts and has no mechanical contact.The food laser coding machinecan mark various graphics, text, and symbols under computer control, making it very convenient to change serial numbers or dates, including automatically marking the current year, month, day, hour, minute, and second. In continuous production processes, it can track and update these data in real time. On many irregularly shaped objects,the food laser coding machinecan also handle the task with ease, and the marking speed is extremely fast, almost instantaneous, making it suitable for marking large quantities of products.

As measuring instruments, scale markings on gauges, calipers, and micrometer lines can all be directly marked with lasers. By selecting a carbon dioxide laser or a solid-state YAG laser, marking can be performed on a variety of materials. For metal materials such as stainless steel, aluminum alloy, cast iron, copper alloy, titanium alloy, etc., an acousto-optically Q-switched solid-state YAG laser is required as the marking light source. For non-metal materials such as plastics, wood, acrylic, rubber, leather, paper products, electronic components, etc., a gas carbon dioxide laser is generally used as the marking light source.
