Signs able to withstand 50C
I have a client that needs some safety signs made up that are in a hot oven type area of the factory. These need to withstand a constant temp. of 50C so I have ruled out plastic substrates but wondered would aluminium composite be ok and could I get away with using ordinary vinyl for this?
Any advice or alternative suggestions appreciated 😀

Think normal vinyl ok to 70 deg but up sell with your nice home made toy to some nice engraved ally plate with paint infill 😀

Probably worth looking into phenolic sheet. Formica, traffolyte spec would be good to look into for that use. We used to use quite a bit of melamine (?) faced phenolic. Not sure where to get it nowadays – we used to get from a company called Vulcascot (I think?), but I’m sure I heard they went out of business or were bought over.

Hi Phil,
Most engraving laminates will be fine at that temperature. We use rowmark as it machines nicely. I can give you contact details if you need them.
Would suspect vinyl would be ok but a you pointed out what backing? How about stainless? Wouldn’t need to be too thick.

Would imagine the composite core will give the same problems as any other plastics but as others have said ordinary vinyl on a different substrate should be OK, depends on quantity but some of the diy places do small sheets of thin aluminium & steel, expensive if you need a lot but if there are only a few might be an option.
Andy, is Rowmark ok on a cnc machine? I thought it was a laser engraving material. if it is where do you get it if you don’t mind me asking, looking for suppliers of different things at the moment.

G’day Phil,
I would think standard aluminium composite and vinyl should be OK – that’s what I do alot of my external signage here with, and outside temperatures in the sun regularly exceed that here, especially dark colours. The UV kills them quicker than the temp, and you don’t have to worry about that.
Cheers

Rowmark do make laser materials but also have a full range of mill engravable sheets too. That said you can mill the laser stuff, its just got a thinner cap thats all.
The textures, lacquers and heavy weights are the best for industrial stuff.

Phill I got an email from some company advertising ceramic signs!
Cant remember much about it but I know ceramics are extra durable and good with heat.
Sure if you googled it something would come up.
Just to add it wasnt hand painted arts and craft applications, more like London place name signs and monuments that sort of thing.
