Novacel, the worldwide leader of Laser protective films

Benefits of Novacel processing and protective films for Laser Cutting

The Laser Cutting process is a demanding one. It was the case with the old CO² technology and remains such with the newest fiber capabilities. The processing and protective films required for this process need to be resilient. Appropriate Laser absorption and resistance to cutting gas pressure are always the main prerequisites for Laser Cutting film.

How do Novacel films work when used for Laser Cutting?

Laser cutting processing and protective films, also known as a laser cutting mask or laser cutting tapes, serves as a temporary layer on materials during the laser cutting process. It acts as an indispensable second skin in a laser cutting process. Without it, laser cutting would not be possible.  It prevents damage or contamination of the material's surface and ensure precise and clean laser cuts. Novacel assists you from the choice of your process and protective film for laser cutting, right through to its removal.

How to apply laser cutting processing and protective films?

Applied on the surface to be cut, the film acts as a shield, preserving the material from potential damage during the laser cutting process.

To apply the processing and protective film, start by thoroughly clean the material and remove any grease, oil, or residues that could interfere with adhesion. Then, ensure that the surface is completely dry. 

If you're using a laminating machine, it's essential to ensure its settings, beforehand, to ensure a perfect application of the laser cutting processing and protective film on the surface. 

Once the protective film is in place, you can proceed with laser cutting. 

Configure your laser equipment according to the specifications of the material and the type of laser film you're using. Conduct a preliminary test on a small piece to ensure the setup is correct. If the test is successful, continue with the laser cutting.

How to remove a laser cutting processing and protective film?

After completing the laser cutting, allow the material to cool, if necessary, and then remove the processing and protective film. Gently peel it off from one corner, pulling steadily but carefully. Finally, give the material a final cleaning to ensure it's debris-free.

Discover the key factors affecting film quality, and some practical tips to ease the removal.

Hi.

If the need for viewing the lasering process is solely monitoring, the most affordable and 100% safe to ones eyes is a camera, connected to a monitor, PC, tablet, etc.
Used ones can be had for free if You happen to be in the right place at the right time, new ones aren’t that expensive either.

Unless You’re talking smaller than A6 “postcard” size, the price sounds IMO/IME too good to be true to be actual laser protective material.
That stuff is crazy expensive as @misken there pointed out.
That’s the ballpark price range I also came up with when hunting for a viewing screen for my DIY enclosure.
So camera it is for me.

I use those for lighting purposes every once and a while, and I seriously doubt that those would work as intended.
Interesting idea though, I have to test it at some point.

If you want to learn more, please visit our website Laser Protection Film.

You can test it as well, keeping mind that when burned/evaporated, the gasses and fumes released will probably cause both health issues for You and corroding problems for Your machine unless the ventilation is adequate.
Just do a low power material test onto paper/wood/etc. with and without a gel on top of the material.
Then You can determine how much of the power is absorbed by the gel and how much goes through.
But do use adequate ventilation and make sure that You don’t inhale the fumes if You decide to test any plastic material.

If your co2 is ir, then how could it possibly cut them?..

They supposedly are made from polycarbonate, polyester plastics.

IR is a very wide range of frequencies… my ir fiber would probably go right through them.

Where did you get the photos? neat…

Lasers are not very useful without a lens. Once it passes through the lens there is a focal point, past the focal point the power drops off very quickly. Put something that reflects the beam and the power drops so much it’s pretty much useless. A couple inches away from the focal point on my 40W co2, I can’t mark a Kleenex tissue… virtually no power… wouldn’t stick my head in there and look at it either.

I’m sure all of us have used a magnifying glass to burn wood or other objects. This is how most lasers work… the beam is focused down to a small point where the power density is much higher… once it’s out of focus there is no power to do any real work.

The sun produces a very wide range of emf, including x-rays and gama rays from the suns corona. This damages the dna in your cells.

Burn is generating a broad spectrum of frequencies aside from the actual laser frequency… When the co2 burns it produces lots of these frequencies of light that can damage your eyes and your protective lenses allow through… using a co2, the IR is not visible to human eyes, but it’s a very bright burn when it operates.

If you don’t know the frequencies of the generated light (emf) how do you know if the safety glasses are really protecting you from other sources of laser generated emf that we know damages your eyes?

After one or two jobs, my brain told me to not look at the cut point, it’s too bright so there must be some type of damage occurring… the fiber is mesmerizing when it runs, so it’s hard not to look … but required now and then.

If you hunt around you can find experienced, highly technical people that have the equipment and knowledge to test these optics. I haven’t heard any of them say anything other than the $250 high end laser safety glasses are no better than the $20 Chinese safety glasses. Who are you going to believe, the salesman or the technical people?

I don’t value testing these glasses enough to figure out how to test them without deep pockets. I would think just diverting the beam and using one of the many optical sensors we have could allow at least a proportional value. It would be non destructive to the glasses and give you a good idea of their effectiveness at that particular frequency…

Sorry I was long winded, but I get tired of decisions generated out fear and not from facts.

All I’m saying is listen to everyone, we all have opinions, good or bad based on something. If the base of the opinion is from an Illumination Engineer, that might be more useful than the guy who’s doesn’t know what a laser is.

Use your knowledge along with your research and your common sense to guide you.

Understand how this stuff works is probably the most important lesson you can learn. Then you can separate the from Shinola. You will be safe, comfortable and happy with your decision… as it will be the best decision you could possibly make.

Then you can add your opinion here

Safety should be on every ones mind at all times when operating any tool/machine …

Good luck…
