Cutting Vinyl already stick to plastics...

Hey Guys!

Just found out some weeks ago, while doing some asked for testing by a new customer, that I can cut vinyl that already stick on plastics such acrylics and polycarbonates with a router (CNC in my case...); feeds and speeds are pretty much the same as when cutting the plastic alone and the vinyl is being cut very cleanily! I was quite skeptical about this but the vinyl proved to be VERY well holding on the plastics!?!?! I'm no sign maker but this customer had ask me this since he was spending MUCH time trying to stick the vinyl AFTER the plastics had been cut (I can easily figure the fun to paste a 4" vinyl letter on the same letter cut in plastic!!!)... or trying to cut both vinyl and plasic with a jig saw, wasting time and material, resulting in a not quite clean finish...

Hope this can be of a use to you!!! :headbang:

My experience with applying vinyl on substrates such as polycarb or acrylic is that I usually use soapy water to apply, then I usually let it cure or set on the acrylic for 24 at least sometimes over 2-3 days before cutting. After that period is comes out really nice. Usually anytime before 24 hours and the vinyl has a tendency to come up or off. My feed rate is the same as plastic, anythign slower and it get a lot of frays around the vinyl surface. I've been using a multipurpose bit at 13,000 RPM/s wih 3 inche/sec. :beer:

WOW! P'etty fast feed!? What bit size?

I have noticed tiny breakage at the machined edge in acrylic if I push the feed to fast using both 1/8" and 1/4" CED bit 2 straight edges standard V-flutes...

About applying the vinyl; that's what I've been told too but this new customer says he's applying it "dry" to avoid the "cure" time but add "one must be experienced to do this..." I've done it for the testing on a small scale with some bubbles since their were dirt on the acrylic...

:lolhitting: Whoops brain fart.

I'm thinking of the job I just did lastweek, that feed speed was using 1/2 PVC and not acrylic. I have a HF 3hp colombo spindle, so sometimes I can come roaring through material :headbang:

The last letter project I did was 1/2" Black PVC with High Performance colored vinyl, when I get a chance I'll take a pic and post . I like using black so I can get away from painting
