I can't find any info on it.. is it because the mould are made from sand?
I'm currently working on an art project for school. For a portion of the project, I wanted to cast a component and put sand in it to give the appearance of a solid mold made of sand. Is it possible to cast a part with sand inside? If so, which type of resin should I use? I've looked into polyurethane but am not sure.
Thanks for any help!
Hey guys! I'm working on a hobby project to create some metal coins from a fantasy universe and I'm looking into sand casting as a potential method, where I would make green sand molds from 3d-printed models and then pour molten aluminium, brass, copper, etc into the molds.
My main concern is whether this method would work with a thin object such as a coin which would be around 3mm thick and have details 0.5mm-1mm deep. Do any of you have experience casting thin objects such as coins with fairly fine details?
I'm totally open to exploring other methods if this isn't plausible, I want to get a solid project plan together before I start spending money on materials. Initially I'm only planning on making a few of each coin but I may look into making 20-50 of each in the future if I have a reliable production method, so methods that minimize the cost and lost materials for repeated production cycles are ideal.
Thanks for your time and stay safe!
so im looking to making some of own molds but ive alwasy used molds that were already made. Does anyone have any advice on sand casting and what type of sand is better for this?
