How is the effect of laser cutting machine cutting PET film? Will the edge turn black and yellow when cutting PVC? How to solve it? Today, Laisai Laser will introduce you to the processing technology of PET laser cutting machine cutting plastic film.
In recent days, several customers who asked me to make samples are cutting PET, PVC and other films. If you use our carbon dioxide CO2 laser cutting machine to cut PET and PI, the edges will be completely fine, and they will not turn yellow or burn. For example, some customers not only cut a layer of film, but also stick a layer of double-sided tape together. We can add an air compressor to increase the blowing, so that the edges will not turn yellow.
The following pictures are all PET films, all cut with a 60W40X60cm table model, and the edges can be said to be very clean, without any burnt yellow. If only one layer of film is cut, to reduce the reflection caused by the bottom plate, the blade plate can be replaced, or a layer of paper can be cut directly below.
For laser cutting of PVC materials, the edges are basically unavoidable to turn yellow. I tried to emphasize the light to just enough to cut through, increase the air blowing to the maximum, and even replaced the laser tube with an imported radio frequency laser and the focusing lens with the smallest focal length lens, but it still turned yellow in the end.
The above is an introduction to the plastic film cutting process of PET laser cutting machine. 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, Laisai Laser recommends that you do proofing before purchasing a laser cutting machine to ensure that the cutting edge effect is what you need. If you need proofing or consultation on the laser machine, you can contact me, Mr. Wu, and I will try my best to solve it for you.
