I don't use this but have a frame job that will require it. How do I cut it? Can it be cut on a wall cutter like foam? Special blade required?
 
Before Frank Sinatra answers from the grave (....it is Sintra....:)):

From a website that sells Sintra:

Sintra® can be shaped much like wood. Pieces up to 3mm thick can be cut with a good shop knife; 6mm sheet can be scored with a knife and snapped on the score line.

For speed and a very smooth edge, you can also cut Sintra® with a circular saw, table saw, band saw, or router. After you're done cutting, you can smooth any rough edges with a file, or with medium grit sandpaper.
 
Most suppliers will cut it to size. This is best if you are using thicker stock and don't have a table saw. Sign Supply USA is a great source.
 
Must have been named after him when he was young since it is smooth and not wrinkly.:D
 
Please remember that Sintra is PVC, polyvinyl chloride, and it will give off chlorine, which makes it a poor component for preservation framing.

You can cut it on a wall cutter, but you need the special Sammy Davis, Jr. attachment using a Dean Martin blade. Peter Lawford and Joey Bishop not required. :icon21:

It's not that hard to cut, and now after you cut it you know you're gonna have to sing out loud "And I cut it my way" :)
 
Sintra, the other kind of Sinatra

...you guys are killing me! Nothing like a good faux pas on the spelling; like I said, I don't use it!

This application is not intended to be conservation and I'm going to be using a thickness similar to foam core - 3/16".

I'll ask my question again in A minor: "Can this be cut on my wall cutter? and are any special blades required?"
 
I've never used it, either. You said you had 'a' frame job to do, so I take it that means 1 picture and not a whole bunch. I would imagine that sintra has to be between foamboard and plexi, so if it doesn't cut in the wall cutter, just cut it on your work table with a utility knife. If it's closer to foam, you will be able to use a knife blade, if it's closer to plexi, you will have to use a plexi blade. Either way, no big deal.

Is there a special reason you want to use your wall cutter?
 
Is this a finished presentation edge you are looking for with a flush mount and no frame. The board can be anywhere from the consistency of a opaque plastic cutting board to the plastic that many photos are mounted on by commercial photo prcessors.

If it is the hardboard and you need a finished edge it needs to be cut on a saw for that thickness. The softer stuff can be cut on a wall cutter. Call sign Supply USA and they will answer the question.
 
I do want a clean edge because it will be exposed. I'll contact sign companies here in Canada....dealing with US firms can be costly.

Thanks for everyone's input.
 
Answered in A minor :):

For a clean edge, Sintra board is best cut on a table saw using a blade designed for cutting plastic. This is especially important if the desired edge will be exposed, and is even more important as the thickness of the board increases.

Sometimes we cut through the mounted image to crop it as required. Other times we slightly undersize the board prior to mounting and then trim the perimeter afterwards.

But the best edge is when they are trimmed simultaneously. I do not think you can get the desired edge on a wall cutter withour dressing the edge afterwards - either by block sanding (and then blowing the dust out of the crevices) - or by the use of a router with a down shear spiral so the top/mounted edge does not distort.

For short run, you would probably be best to subcontract.
