Casting Parts in Urethane: Tips from a Master

Casting Parts in Urethane: Tips from a Master


When you want a few copies of something, you can 3D print them. When you want a ton of them, you might consider making a mold. If those are the shoes you're in, you should look this video from [Robert Tolone] (embedded below). or heck, just check out All of his video.


Even in this single video from a few years ago, there are a ton of tips that will help you when you're trying to pour just the right color resin into a silicone mold. Mostly, it all boils down to testing a small amount before bulking it up, as a lot changes along the way. and there [Robert]Let's experience shines - he knows all the trouble spots you need to test for.


For example? color matching. Resin dyes are incredibly concentrated, so getting the right amount is difficult. Mixing the color in a high concentration first and then gradually reducing it allows for more control. But even then, the dry product is much lighter than the blend, so some experimentation is necessary. [Robert] The sea foam sneaks onto the right hue of green and then pours a few test batches. And then he pours it into the exact size of the mold to make sure.


This is one of the tips in this video, which is just the tip of the mold-casting iceberg. Pour yourself a coffee, settle down, and you'll definitely learn something. If you are into more technical parts and CNC machining, We still love Guerrilla Guide after all these years.


thanks a lot [Zane] To lead us to this treasure.
