What It Is Like To Have Laser Marking Of Polycarbonate?

By David Long


The procedure in laser marking would refer to technique in labeling or marking materials and the work pieces with used of laser machine. There are different applications that might require assorted techniques yet the annealing, foaming, removing, staining and engraving would be the common marking ways. Every laser marking polycarbonate would have own disadvantages and advantages that would depend in materials used.

The laser marking would give one the absolute freedom on markings graphics, serial numbers and barcodes in any kind of plastic material. The laser would allow the marking of any kind of content or detail, even the small that has high definition, then guaranteeing the utmost quality and readability. The marking would resists tear and wear, contact with the acids and heat then ensuring the case that has complex data would be fully traceability over time.

In foaming process, laser beam would melt the plastic flat surface on localized area then create the small bubbles gas on material it completely cools down. Those gas bubbles would reflect the light in diffused way. Then afterward, gas which would accumulate inside would increase the volume of material that would create the sort foamed plastic.

Those fundamental properties would make that possible in using the laser light on lot of areas in modern material procedure. That intensity would be preserved for long time that is due to coherence and could be bundled would further throughout the lenses. Laser beam would impinges on material in removing, completely evaporated and changed.

The plastic absorbs the light from beam. The color pigments and the carbon on plastics are vaporize and destroyed as result in localizing heat. In that point, one would notice foaming and see color change. That would depend in composition of component.

The raster engraving would be common way in engraving and would refer the line by the line or the point on point from pixels in designed graphic. The vector scoring refers the laser machine trace the curves and lines of the graphics after other while the engraving the same time. For applying with much larger areas like stamps, shaded lettering, wood engraving and images that more be appropriate.

The carbonized marking should process which produces the strong contrasts in bright surfaces and commonly be used in bio polymers or polymers like wood and leather. In carbonizing the material, light would heats the surface emitting hydrogen, oxygen or mix of both. The carbonizing would lead in dark marks in higher concentration of carbon and contrast rather shown minimally in darker materials.

It should be shorter ray wavelength like five hundred thirty two or three hundred fifty five could produce in higher results of the detailed. Those short wave length beams would produce less also thermal reaction in material. It is clean procedure with the near into zero wasted like byproduct.

Therefore, none of surprises which has lot of thousands in laser machines marking that are dedicated in marking products that is made of that polycarbonate. There are manufacturer that has wide range of laser engraving and marking solutions configured ideally for the cutting and engraving in all kinds of the materials. The experts would happy in recommending that configuration suits the application.
