In the process of making samples for customers over the years, we have come into contact with a lot of products made of plastic materials, such as plastic computer keyboard keys, plastic instrument casings, plastic mobile phone battery covers, plastic massagers, plastic floor heating switch panels, etc. This shows that plastic materials are widely used in production and life.
First of all, we need to understand that plastic is a general term. There are five major types of general plastics, namely polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and acrylonitrile-butadiene-styrene copolymer (ABS). Because different materials have different laser absorption, we often test samples first and then recommend suitable laser marking machines when we receive customer inquiries.
Fiber laser marking machine, CO2 laser marking machine, UV laser marking machine, in fact, these three laser marking machines can mark on plastic products, but the effect is still different. Generally, fiber lasers are good for marking hard plastics such as PE and PVC, and CO2 can also be used, but the effect is worse. Laser marking machines have been developed to the present, and many customers use them. The range of industries and materials that can be marked is also very wide. Nowadays, PVC materials are also marked by fiber laser marking machines.
