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