Hydraulic Vacuum Press

Macrodyne Vacuum presses are custom heavy-duty hydraulic molding presses with vacuum chamber enclosure to remove air from the pressing chamber, reducing the amount of heating, pressure, and bumping required to produce uniform and consistent parts.A hydraulic press is made up of two interconnected cylinders. Each cylinder is filled with hydraulic fluid, and one is bigger than the other. The bigger cylinder is referred to as the Ram, while the smaller one is referred to as the Plunger.The simplest type of vacuum press uses a sealable bag and some form of vacuum generator. By placing materials in the bag, sealing it and then sucking out most of the air, a pressure differential is created between the reduced pressure inside the bag and atmosphere on the outside.
