Abstract

This article presents the results of research, design and integration of a laser equipment system on plastic materials using a UV laser of wavelength 355 nm, power of 5 W, integrated from semi-finished modules available on the market. The research team investigated the influence of technical parameters on the UV laser engraving process on plastic materials such as wavelength, output laser power, pulse width, engraving speed, engraving area size, electricity source... As a result, the research team has come up with a set of parameters for the manufacturing equipment system for a number of specific plastic materials. Some experimental UV laser engraving products on plastic materials of the manufactured equipment system show images with high sharpness and contrast, small heat-affected areas, can engrave sizes as small as micrometers, with a high speed. Research results showed that UV laser equipment is a good choice for laser applications in the semiconductor industry, micro-mechanics, medicine and peripheral equipment...
