                          is it suitable to purchase a positive and negative pressure or negative pressure machine under what circumstances ?



If the customer manufacturer locates the high-end route, the positive and negative pressure laminating machine can be purchased if the three-dimensional effect, gloss, etc. are required.

 

If the project has just started, users who are in the trial phase can consider purchasing a negative pressure machine. Generally speaking, the negative pressure machine is suitable for the transition period, and the positive and negative pressure laminating machine are basically the main ones.


So what is the difference between positive and negative pressure?


The positive and negative pressure laminating machine, generally speaking, not only has a negative pressure (vacuum pressure) underneath, but also a positive pressure on the top. When the machine is operating, the bottom is pumped and the top pressure is drawn, not only is the bottom negative pressure vacuumed, but also the top pressure is added, so it becomes positive and negative pressure. The negative pressure machine is only vacuumed from the bottom, and there is no pressure on the top, so it is called a negative pressure machine. Blister machine and negative pressure machine are different names of the same concept. Of course, the machine will not only pass the "pressing" step, but also have to cooperate with heating and other processes to become a complete laminating process.
