Custom plastic molds
 

Looking to have a custom mold made, that's durable enough to install in a concrete wall and be removed, leaving the impression. Picture the dates imprinted into bridges if you've ever noticed them before.

Anyone do this, know someone that does, or has a place they could recommend?

Not cheap, but fast. /shrug.

Do you need lots of different molds, a lot of the same mold, or just a few one offs?

Just 2 one offs. 1 Logo mold and one "EST. 1965" mold.

Thanks for the link I'll check them out.

I feel like you might be better off just getting a machine shop to cut you a positive mold out of aluminum or a block of delrin in that case?

How big are they? I might be able to help if you just wanted them machined out of a block of aluminum or some sort of plastic.

I want one of our company logo, roughly a 20" wide oval and a simple "EST. 1965" text maybe 1' wide.

What I'm doing is pouring a slab in the front of our shops office and I want to have a 4' wall coming off of it with our logo imprinted into the wall. Going to have some small spotlights coming out of the slab to light it up. Little monument type deal.
