How well does the laser cutting machine cut PET film? Will the edges of cut PVC turn black and yellow? How to solve it? Today Redsail Laser introduces you to the processing process of cutting plastic film by PET laser cutting machine.

In recent days, several customers who asked me to make samples are cutting PET, PVC and other films. If you cut PET and PI with our CO2 CO2 laser cutting machine, the edges are completely fine, no yellowing and no scorching. For example, some customers not only cut a layer of film, but also stick a layer of double-sided adhesive paper together. We can add air compressor to increase the blowing air so that the edge will not be yellowed.

The following pictures are PET film, are cut using 60W40X60cm table model, the edge can be said to be very clean, a little scorched yellow. If only one layer of film is cut, to reduce the reflection caused by the bottom plate, you can replace the knife strip plate, or cut a layer of paper directly below.

For the laser cutting of PVC material, its edge basically can not avoid yellowing, I tried to emphasize the light to just cut through, the blowing gas to the maximum, and even the laser tube replaced with imported RF laser, focusing mirror also replaced with the lens with the smallest focal length, and finally there will still be yellowing.

The above is the PET laser cutting machine plastic film cutting process is introduced. There are many plastic components, in addition to PET, PVC, PI, there are PP, PS, ABS, etc.. The actual cutting effect of the material should be based on the actual proofing test. Therefore, LASER recommends you to make a sample before purchasing the laser cutting machine to make sure the cutting edge effect is what you need.
