What is the difference between positive pressure, negative pressure and positive negative pressure forming machine?

The positive pressure forming machine directly exerts pressure on the sheet material through the die punch to form it in the die. The negative pressure forming machine can quickly extract the air between the sheet and the mold through the air pump to form a vacuum negative pressure so that the sheet can be formed in the mold. The positive and negative pressure integrated molding machine combines vacuum extraction with positive pressure, which has higher molding accuracy and can produce more complex products.
