laser marking on polypropylene sheet

Because laser marking technology has the advantages of cleanliness, high efficiency without damaging the matrix material, and high resolution, its marking on synthetic resin has increasingly shown its unique advantages.

The principle of laser marking is to use laser radiation to generate local high energy in the polymer matrix. This energy is absorbed by the polymer matrix or additives and converted into heat energy, thereby triggering various physical or chemical changes inside the polymer to produce a marking effect.

In recent years, the application of laser marking on plastic materials has developed rapidly. At the same time, laser marking technology has also been widely used in the production workshop of storage batteries.
