I was just thinking about this. My buddy who makes fishing lures uses syringes that he cuts for funnels to pour his Alumilite resin. Normally for a larger part the resin flows everywhere it needs to go. And I don’t have any experience doing two piece molds for tiny parts. But I would like to make some smaller parts and am worried the resin won’t flow to all the small details without some force behind it. Has anyone used a syringe to inject resin into their molds. Seems if you did it this way you could use fine air relief veins of a very small diameter and force resin to every part of the pattern and the air would be forced out with the incoming pressure of the resin. Isn’t this more or less how injection molding is done but at a more rudimentary level? I don’t want fancy equipment I want simple. If it doesn’t work then I would rather buy detail parts. But seems to me this should work.
Has anyone experimented along these lines?
