multi layer plastic sheets (different colours)

Postby Jason Wright » Fri Nov 18, 2016 12:28 am

Hi there,

Im sure you can gt a plywood type plastic sheet but i dont know what its called , if i knew that i could start to look where to buy it,

Im sure you know what i mean but ill explain, say its a red colour on the surface but has a white layer underneath so you can etch though the red layer to expose the white underneath.

Any ideas?

cheers

It's called multi-layer sign plastic or multi-layer sign sheets. I did a quick google search and got far too many results to post here. Too many choices, not enough (fill in the blank).

If you are thinking thin (.020- .060) it is called micro plastic (Gemini Duets & Romark). Gene

I work a lot with this plastic (here called bi-layer= bicapa), i test gravoply and rowmark, both similar quality.
There are interior and exterior (UV protection) "models", and a lot of combinations (top color/ letter color), normally 2 mm thick, but they have a thin bi-layer with aluminum / silver / gold finish, maybe 1 mm, then this is a flexible material to adecuate to curve surfaces, etc
Here offer too a "noname" by-layer, chineeeeeese by-layer :) , a half of price, only interior use, and for me, not bad material.

I attach a photo of one of my first test (2 year ago) with by-layer, after more test, i can get a better engraving with this parameters :
The ruler is in centimeters

I use minimum power (for me 26%, below that not fire), vel 400 mm/s and interval 0.1 mm to engraving
And 90% power, 18 mm/s to cut

Is a really smelly material when you engrave/cut it !!!

The thicker mult-ply plastic is more for mechanical engraving or routing- one mfgr is King Starboard. Gene
