  • You are correct. if you making many parts, build a pattern. If you doing very short run or one off's, mill the sand. It's a lot cheaper and much, much faster. Users can have ready to pour sand in less time than it takes the glue to dry.

  • That's what I would have guessed, but I wasn't sure. I've done a fair amount of sand-casting using wooden patterns. If you're doing a "one-off" part, I can see how your method might be appealing, but if you're out to make more than one copy of a part, it seems like it would be better to mill a pattern and then use the pattern to do conventional sand casting, wouldn't it?

  • What you are seeing in this video is for the founrdy industry. Normally to make a casting you first make a pattern. Then sand is packed around the pattern and the pattern is removed. This leaves a "mold" that the molten metal is poured into. Using this process shown in the video you can cut out the cost and the time required to make a pattern. It's MUCH faster and MUCH cheaper.

  • So, what are we seeing, and why is it unique? What's the finished product?
