Hi All

Need some tips for cutting silver or gold mirrored acrylic. I recently purchased a HPC LS3020 laser cutting machine. It cuts coloured acrylic upto 4mm very nicely however a bought some silver and gold mirrored 3mm acrylic recently...I have 2 different sorts of silver mirror one has a smooth white backing and the other a grey tape texture. It cuts the white backed silver mirror really well however the grey backed silver and gold mirror burns when lasered and a small flame is produced. Normal acrylic does not burn or produce a flame. Whilst my air assist blows the flame away, the finish is charred and slightly melted.

I would like to purchase more of the white backed stuff in both silver and gold mirror but I don't know exactly what it called.

Also am I actually cutting the grey backed mirror right, 80% power 12 speed works well on normal acrylic but not the grey backed ? Is my air assist enough. Any guidance would be much appreciated...

Regards
Steve
