Laser Marking Plastic Parts

Laser marking on plastic can be obtained with either a co 2 or a fiber laser source.

Laser marking plastic parts.

Generally the fiber laser generates a white mark on any plastic base color. A fiber laser from epilog is the perfect choice for marking engineered plastic parts with barcodes serial numbers and logos. Can you laser engrave plastics. The co 2 laser is more often used for etching or engraving on the plastic.

The laser choice will depend on the application requirements. Welding use the heat of laser radiation to weld and join plastic parts. It s been a reliable workhorse across a whole spectrum of industries for decades. Laser systems are the ideal choice when permanent high quality marks are required on parts during production.

Color change in an injection molded part made of light plastic is brought about by means of carbonizing. Direct ink printing puts an image on the surface of the plastic which can be removed by abrasion or solvents but laser marking can provide an indelible high contrast mark in the material itself with no direct contact with the plastic other than through the incident laser beam. Laser marking is fast and maintenance free making it an attractive alternative to ink jet marking chemical etching or labels. Laser marking of plastic or plastic engraving is a process during which components are labelled or marked with the aid of a laser.

So laser marking is a practical solution for plastic parts. The polymer that the plastic parts are made up of dictates the methods used and the energy input needed to laser mark the plastic. This application is typically used for permanent and durable marking of housings of all types relays switches plugs and other electronic components. Laser engraving involves physical removal of a section of the plastic surface using the laser beams.

The removal of some part of the material hence results in a cavity which comes in the form of a graphic or text as desired. Laser marking expert q a. Laser marking is fundamentally different from ink printing the traditional method of marking on plastics. As government and industrial regulations for clearly legible permanent marks and serial numbers on medical and aerospace parts increases laser marking laser etching and or laser engraving or scribing is rapidly growing in need.

Laser marking technique is best suited for bar codes logos id codes etc.
