How a Pneumatic Press Works (With Pneumatic Valves, Of Course)

pneumatic press in factory

A pneumatic press gets its primary mechanical action from its pressure source derived from compressed air. The mechanical actions from a pneumatic press range from shearing, punching, bending, forming, drawing, extruding, and assembly. Such presses are used in mechanised binderies for a variety of purposes and offer the advantages of speed of operation and cleanliness. A fully pneumatic power press uses a pneumatic system or pneumatic valves for its power, compared to mechanical or hydraulic presses that utilise mechanical or hydraulic fluid for powering rams.

The difference between pneumatic press and mechanical and hydraulic presses

Mechanical presses

Uses manual labour-power to operate the press for purposes of shearing, punching, or bending. Its pressing power is limited due to the absence of any external pressing power from a pneumatic source.

Hydraulic presses

Uses a liquid that moves under pressure. A piston pushes down inside an oil-filled chamber that pushes down on the press and applies pressure for pressing or any other purpose. Hydraulic presses can do more heavy-duty work compared to mechanical and pneumatic presses. However, hydraulic presses are high maintenance, prone to leaks, and are highly flammable due to the use of oils.

Advantages of the pneumatic press

  • Pneumatic presses are easy-to-use, durable, and low-maintenance. They also operate faster than mechanical and hydraulic presses, and can be stopped any time if necessary. Pneumatic presses are dependable primarily because of the use of dry and moisture-free air that doesn’t create any problems for internal parts. They are also less complicated than hydraulic presses.
  • Pneumatic presses carry many commercial and industrial application benefits. They offer fast, clean, affordable, and low-maintenance power for machinery across many industries. In terms of leaks, if ever there should be one, only air is escaping. On the other hand, if a hydraulic press leaks, oil is seeping out, and this increases the flammability of the escaping oil that can flare up anytime even from just a small spark.

When a pneumatic press is leaking, all that needs to be done is to plug the hole so air stops escaping. A leaking hydraulic press that is leaking means the machine loses fluids that require time to clean up, causing labour downtime.
