Plastic engraved signs

Postby Phil » Sat Jan 13, 2018 9:33 pm

I've been asked to make some small plastic engraved signs. Like these https://www.amazon.com/Custom-Engraved- ... stic+signs
If anyone is making signs like this I'd like to get some basic info.
- what is the name of the material
- where do you get it
- what type of bit do you use to engrave
- other than engraving how do you cut it/

Thanks in advance

Although I purchased supplies for my laser, you can get supplies at Johnson Plastics, who also owns Laserbits( www.johnsonplastics.com ). I remember somewhere on their site was instructions for their products. You might look there. Gary

I have made name plates for our Vet’s office, and for some volunteers with Great Dane Rescue on North Texas, and have gotten the plates from NameTagCountry.com

I tried using different bits but always ended up melting the plastic into a glob on the bit which ruined any lettering, etc. On a whim thought i would try using the laser that i got with my HD4 Shark, and excellent results.

Phil, what you are looking for is an engraving laminate, probably the 2 best known trade names are Rowmark & Traffolyte :lol: , saerching any of those should throw up some suppliers, sorry my suppliers would probably be to expensive with shipping across the pond :lol: :lol:

Comes in rotary & laser engraving varieties, for the sort of work you are looking at then either a 1.5mm or 3mm thickness would be appropriate ( or the imperial equivalent )

If rotary machining then hold down can be a problem without a vac bed, I use engraving bits to machine, flat size varies a lot depending on text size :lol: :lol:

That should get you started, no doubt others will add to the thread :lol: :lol:

You can easily go into sticker shock pricing this color core material.

I use a poor mans solution all the time, simply paint over white plexiglas [acrylic] with color of your choice and engrave your design [drag bit or rotary], produces much the same effect.
Example below was backlit but no reason why you have to, nice option to have though.
Probably not recommended for outdoors.

Another example of the same effect, this one in clear plexi with multi color - Blue background could have been any color, white objects and font could have been any color ,, Could use 5 different colors if you wanted, something not possible with core material.

Not ragging on core material, I like it and have used it myself [though, as mentioned, some of it is often better suited to lasers than routers].
I find it uneconomical for my purposes, and limited on color options.
