What are the requirements of laser marking for plastic products?
And the use of laser marking machine in plastic surface marking is a kind of fast processing speed, can keep the plastic products inherent surface properties, the characters or patterns with the plastic into a unified whole advanced marking technology. Laser marking machine uses laser beam to produce mark directly on plastic surface, including mark, code, character, numeral, pattern, line, two-dimension code and so on, and it is formed by one mark, without other processing step.
Compared with other materials, plastics have the following characteristics: light weight, excellent chemical stability, excellent electrical insulation performance, wide mechanical strength distribution and higher specific strength. Based on the above characteristics, become the most commonly used plastic packaging materials, plastic products trademark, barcode and number for identification mark printing, usually by labeling, packaging and other processing methods of hot stamping contraction, or directly at the surface of the plastic mechanical processing, such as printing, engraving, punching and pressing
