Advice fabricating plexiglass letters?

[levakbob]

Hi all

I was wondering if anyone has any experience withe acrylic bending lettrs.
How to bend plexiglass?

Many thanks Radek

is that even bending? looks more like acrylic welding to me... routed panels with a miter'd edge (45 degree) glue'd together to form the letter itself.

saw a LOT of stuff like this the few times I was in europe. seemed like the standard there as opposed to channel lettering like we have here in the states.

I've only had experience with a strip heater for making little displays/stands, and had very minimum exposure to that. With thermoforming, be it little displays like I made, or great big fast food signs, generally the edge is rounded instead of sharp, so I'd concur with MikePro in that it is machined as smaller parts and acrylic welded together.

I tried just heats plexiglass. The edges of a plastic strip I ever started to sag. I do not know what I'm doing wrong.

Labor intensive, but looks nice, Gemni call them Minnesota letters I believe.

Levakbob... your saying you are making these, and it's not working.?? more info please.

Looks like solvent bonding to me.
To bend Acrilic requires heat. Polycarbonate can be bent cold.

A syringe works well to control the solvent.

it is pieces welded together and then the routered face panel welded to it. No bending was done to the letters you posted a pic of

I agree the pieces are welded. you can see the cut areas where faces come together. forming that precise is practically impossible, the edges will have a slight rounding to them.

just find a cnc guy, have him cut the panels to fit, weld, flame polish, done.
