What Is an Air Over Hydraulic Press?


three kinds of AIR OVER HYDRAULIC PRESS

A hydropneumatic press, or air over hydraulic press, combines compressed air and hydraulic oil into one system. As a clean, reliable alternative to hydraulic presses, air over hydraulic presses are used for a wide range of industrial tasks, including punching, bending, riveting, forming, and more. This type of press offers a wide range of benefits that make them suitable for various industries and applications.

Air Over Hydraulic Press Overview

Used to perform a wide range of functions, the air over hydraulic press delivers the powerful force of a hydraulic press combined with the enhanced control and efficiency of a pneumatic press. The air over hydraulic press is initially driven by compressed air. When it encounters resistance, the hydraulic power is automatically activated. This innovative technology can help you save space, reduce your energy expenditure, and so much more.

Air Over Hydraulic Press Benefits

The advantages of using air over hydraulic presses include:

  • They’re small and lightweight, and there’s no need for a hydraulic power pack.
  • With compressed air as their primary power source, they allow for a quicker approach and retraction.
  • They use up to 50% less energy when compared to fully hydraulic and pneumatic systems.
  • They offer an overall savings of up to 70% over traditional hydraulic systems.
  • With simple sealing components and pneumatic elements, air over hydraulic presses are easy to use.
  • These presses eliminate the need for expensive hydraulic oil and other hydraulic components.

Air Over Hydraulic Press Applications

Air over hydraulic presses are commonly used for a wide range of industrial tasks, including:

  • Bending
  • Riveting
  • Forming
  • Marking
  • Clamping
  • Punching
  • Straightening
  • Shearing
  • Die setting
  • Embossing
  • Forming metals and plastics
