The difference between positive pressure molding machine and high-speed vacuum blister machine
The simplest way is that the positive pressure is formed by air pressure (blowing), the mould needs to be sealed, and the air compressor is needed. Vacuum forming is a negative pressure (suction) molding, and a vacuum pump is needed
