Sand Casting with Pattern Resin
January 27, 2010 - 1:28 am
Panic button lettering and design are made on a computer and created by exposing pattern resin to blacklight. The pattern is molded in petrobond sand and a casting is made. Visit www.granthams.com/Projects for more of my projects.

A search for hard pattern resin on Google comes up with all kinds of resins. Obviously you use one that cures in UV light and is water soluble. Any hint for an on line source? A part number of what you are using maybe and Mfr..

You’ll still need some good milling and turning machines to get it usable for vehicle. You wouldn’t want it to be out of round, off center. Attempting that will be hard since if you get it wrong, it may shatter at high speeds.

You use a piece of conduit (thin wall pipe) to remove sand. Just press it gently into the sand either on top of a flat area of the pattern or to the side of the pattern. Sand goes into the pipe then is pulled out when the pipe is pulled out, leaving a hole. You then just use a knife to make the top of the hole beveled so that it’s easier to hit the hole while pouring.

Question:
After you added the second half of the flask to the top, I did not understand this part. It seems that you added more sand to the second half? But then later, how did you get that circle inlet in the second half, the shaft in which later the metal gets poured into. I did not understand that part, how the second flask piece was assembled.

I was wrong. Software helps. The thing I was thinking about was that signmaking software by Vectric, I think. Nice, crisp corners cut with a V bit – of course, they’re beveled….

Regardless of which tooliing you used, you would always be left with a inside corner radius. Nothing at all to do with software packages.
Software dosent make square corners, tooling does

With CNC you’d have a bunch of ugly tooling paterns to real with. With small tooling, it would be slow too. Trust me.
Also, you’d never get square inside lettering corners on a CNC mill.
