Application of 10w Ultraviolet lasers marking plastic buttons

The focusing spot is small, and the processing heat affected zone is very small, which can carry out ultra-fine marking and special material marking.

At present, plastics are widely used and are indispensable components in home appliances, automobiles, mobile phones, PCs, medical equipment, and lighting appliances. Benefiting from a good external environment, the industry has also achieved rapid development, and the development of downstream industries has further boosted the demand for plastics.

With the rapid development of the plastic industry and the continuous improvement of plastic performance, plastic parts have been more widely used. Plastic parts are replacing traditional metal parts in different fields. A properly designed plastic part can often replace multiple traditional metal parts. , so as to simplify the product structure and save the manufacturing cost.

And some plastic buttons will need to be marked with some icons, such as mouse, keyboard, remote control and so on. The traditional marking method on plastic buttons will fade and fall off due to frequent touch, so it will cause some trouble to people during use, especially on some important buttons, the marking is very strict, and In order to mark the plastic buttons beautifully and for a long time, they have to use a laser marking machine to mark them.

The laser marking machine uses a laser beam to mark long-term marks on the surface of various materials. The effect of marking is to expose the deep material through the evaporation of the surface material, so as to engrave exquisite patterns, logos and characters, and the marking is clear and long-lasting. The laser marking machine has good beam quality and small focusing spot, which can realize ultra-fine marking.

The reaction mechanism of RFH's plastic key laser marking machine is realized by photochemical ablation, that is, relying on laser energy to break the bonds between atoms or molecules, making them gasify and evaporate into small molecules. The focusing spot is small, and the processing heat affected zone is very small, which can carry out ultra-fine marking and special material marking.
