Lasering aluminum cake pans

[mike klein]

I have a customer that has some bare aluminum cake pan covers they want their logo engraved on them. Does a person have to use thermark or cermark on them or can a co2 or fiber mark the bare metal.

your fiber can mark them easy enough, but I'm not familiar with gantry fibers--

Your 60w Epy should be able to Cermark them if black is okay. My 40w metal lasers won't Cermark aluminum reliably, but my 80w glass laser does-

But a C02 with your wattages won't do squat to aluminum by themselves...

I'll give it a try with the fiber and see what happens.
