What is a hydro pneumatic press machine?

As its name demonstrates, this type of press machine utilizes air as well as a liquid fluid in order to generate and transmit power, thus takes advantage of cons of both systems. At first, a hydro pneumatic press machine starts to operate through the power of transmitted compressed air and spontaneously runs the hydraulic system.

The hydro pneumatic pressing method is highly in use in various industries. Hydro pneumatic press machines operate in three courses (Steps, Stages):

Various types of Hydro Pneumatic Press Machines:

Hydro pneumatic press machines are in use in various types of tasks such as assembly lines, sheet stretching (Drawing), stamping, cutting and shearing, pressing, bending and riveting (joining).

Advantages of hydro pneumatic press machines:

1. Compressed air is the main and initial source in order to run this system, which makes the design and production of this machine, more economical in comparison to hydraulic ones.
   
2. Hydro pneumatic press machines are light and occupy less space in comparison to other types of press machines, which make it possible to place them in cramped rooms and small spaces. These machines are even able to be placed on tables.
3. Utilizing a pneumatic system in the structure of these machines, boosts their speed and makes them perform much faster.
4. Hydro pneumatic press machines save energy and resources up to 50 % and 70% in comparison to hydraulic / pneumatic systems and older press machines respectively, which is one of the main parameters in reducing the production expenditures.
5. The reduction of repair and maintenance costs is because of using fewer moving parts (Mechanical Parts) in the structure of the machine and also occurrence of lesser corrosion is the consequence of utilizing a pneumatic system.
6. This type of press machine makes less noise and vibration, which makes it more accurate.
