If I may, I'd like to make 2 suggestions if you make another similar video. 1, if you want to compare the two, make sure you're using the same units. The positive pressure didn't sound impressive when you didn't use the same units to describe the vacuum. Similarly, suggestion 2, you introduce each vacuum piece first and talk about how bad it looks. However, the audience doesn't see what it is supposed to look like first so again, we can't agree or disagree with you. Start by showing the original part first or the positive pressure version so we can see how the "bad" version errors ourselves. When you eventually do the swiping screens to do a 2nd compare, maybe pause or hold in the middle since several of these examples are symmetrical and our eyes can see what you're talking about.
interesting concept , will work perfect on small parts , with bigger parts you would need a lot of stored air and a pretty big diameter pipe to deliver it within a verry small timeframe , allso the bigger the part/ pressurized container the bigger eeehr bomb you potentially have , like you said you can apply more force ontoo the part being moulded but that same force is pushing against the walls of the box holding it in , if it lets go the air inside it increases intoo one time more volume of the inside of the box for every atmosfere ru-vid.com3ODSz4WISNo inmagin standing next to it holding the box down to seal it seen the same thing with an airplane tire in a shed , there was no shed left , they now use water to pressuretest still consider using the option for bigger parts in combination with a vacuum on the other side though as a bit of a turbo boost and a way to cool down the part faster maibe 2 or three atmosfere tops might use a set of leafblowers or a bouncy castle type blower
