Marking on White Plastic

Laser marking is fundamentally different from ink printing, the traditional method of marking on plastics.

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.

And it is with no direct contact with the plastic other than through the incident Laser beam.

This application insight looks at Pulsed Fiber Laser marking of plastics focusing on the four key types of mark.

Just like foaming, engraving, engraving with colour change and colour change only marking.

It also explores Laser marking of different types of plastic including ABS, polyethylene, polypropylene and polycarbonate, and why our Pulsed Fiber Laser is the best tool for the job.

Many consumer electronics products are made from white plastic, and some consumer electronics products have a transparent hard coating.

It is difficult to achieve smooth marking on this type of plastic using standard ns pulsed lasers because it tends to melt the hard coating.

Tests have shown that good marking can be obtained using a relatively low frequency short pulse laser.

The sample shown was produced using a 3 ns pulse at a scan speed of 500 kHz / s at a frequency of 150 kHz, resulting in a smooth mark with a uniform appearance.

It is important to optimize line-to-line shadow spacing and scanner synchronization delay to achieve this type of marking.

Precision instruments ,plastic ,glass UV laser marking machine. Brief Introduction:

UV laser marking machine is one type of laser marking machine.

Main feature is 355nm UV laser source.

So Compared with infrared laser, UV light has very small spotlight , it can reduce the material mechanical deformation to a large extent .

also produce a little processing heat.

It is mainly used for ultra-fine marking and carving.

especially for food, pharmaceutical packaging materials, glass material , silicon Chip wafers, etc.

Working Principle Details:

The working principle of UV laser marking machine is similar with common laser marking machine.

So They just make permanent marks on different material surface by laser beam.

also The marking effect can evaporating the surface material to expose the deep material.

Also to „mark“ the trace by the chemical and physical changes of the surface material caused by the light energy.

And burn some of the surface material by light to show patterns and text.

Advantage Details:

Because of the super tiny focusing UV light spot and very small area affected by heat processing, it can used for ultra-fine marking, special material marking.

Thus, it is the preference for customers who has higher demand for marking.

In addition to copper material, UV laser is more widely used.

So First ,Better beam quality and smaller focusing spot.

Second ,Can achieve ultra-fine mark.

Third ,The scope of application is more extensive.

Fourth,Does not produce thermal effect.Will not produce material scorching problem.

Fifth , High mark speed, high efficiency.

Sixth, Stable, small size, low power consumption.
