I've heard that it is possible to make thin wall diecasting metal prototype by investment casting with vacuum assisted.
Would anyone kind enough to share their experience,no matter good or bad, on this topic with me?
I've heard that The SpeedVac 960 system from SpeedForm in Germany can do such kind of job.
Would any SpeedVac users share their experience with me?
