The Use Of Superwave Laser Marking Machines On Plastic Products-SUPERWAVE LASER
Plastic material is a kind of important products, plastic products, such as bar code and serial number is used to identify a trademark of the tag, general usually adopt surface direct mechanical processing, such as stamping, engraving, punching forming tags, or it is printing, adhesive labels, packing decoration contraction generate external processing way. And the use of laser marking machine in the plastic surface printing is a kind of high processing speed, can keep the surface of the plastic products inherent features, and print the tag has the characteristics of lasting, anti counterfeit and high quality, do not need other processing operations.
Some plastics are easy to be labeled because they are easy to absorb energy, while some plastics do not absorb the laser and can not be used to generate the marks. The absorption rate of laser energy is a function of wavelength. Therefore, under the same laser strength, different plastics can be marked with different qualities.
For example, some nonferrous high-density polyethylene and polycarbonate are used in YAG lasers without adding any additives to get the desired impression. The CO2 laser marking machine is not printed without special additives. In addition, plastic degradation, crack, surface cavity and so on, will also mark down quality.
Nowadays, plastic products are widely used in various industries, such as: home appliances, automobiles, mobile phones, PC, medical devices, lighting appliances, which are indispensable parts!
