Laser cutting aluminium sublimation metal?

[Warrior]

We currently use a guillotine to cut small metal plates for trophies from A3 sheets of coated sublimation metal, 0.5mm thick.

Has anyone used a Laser cutter on sublimetal and if so is the Polyester coating effected in any way?

I'm guessing the heat will be an issue, but due to the thickness of the material wondered if the speed of the laser would help?

You cant use a normal CO2 laser to cut metal. Anything with sublimation coating does tend to burn.

Ok, many thanks....

I'm trying to create a jig to take 50mm x 20mm, 50 x 25mm etc., trophy plates to avoid having to stick each one down individually. A nearby company with a laser cutter can help with this and I was hoping we could go a step further and have them cut some plates out as well.

Cutting the metal sheet down ourselves saves a lot of money but obviously takes up time. That said if we buy in ready cut plates removing the plastic off each one takes just as long. (We take the plastic off of the full sheets before cutting down)

We get chromaluxe laser cut.
The thinner metals are too thin don't work well.
There is a crud left around the cut edge, whoch needs scrubbing off with isopropyl or acetone
There is also a sharp burred edge that needs filing/sanding down.

Needs to be proper big Industrial cutter for metals, not a hobbyist who does wood/acrylic as that will just cut the polyester surface and not touch the actual metal

Try to find someone with a CNC machine to cut them to your requirements, not a laser.

Thanks...

The company who I'm hoping can help with this does Laser and CNC.

I'm calling in a favour through a friend and waiting for some advice, prices etc.,

I have an xtool D1 Pro 10watt diode engraver if you want to send me a piece of what you want to try and cut I'll give it a go for you

Many thanks but all sorted thanks Bob....

We had the templates cut out of stainless steel and whilst the tolerances we require weren't met due to a break down in communication we learnt enough to believe there's a better way of achieving our aims so are now looking at using 3mm thick aluminium and machining the cut outs a fraction under the engraving plate thickness.

One of the reasons for using aluminium is that the steel sheet held the heat for ages and I'm told we'll see some improvement?
