Hydraulic & Pneumatic Presses: A Comparison
05 May, 2010- Hydraulic presses and pneumatic presses perform more or less the same operations but with individual distinctive features. Below are few differentiations among both:
MECHANICS
FEATURES Pneumatic Presses
The biggest advantage of pneumatic presses is their speed. These presses can boast of moving ten times faster than the hydraulic presses. These are flexible enough and can be stopped at any time to release the air. Besides, pneumatic presses are extremely portable and can be adjusted anywhere within the work station. Extremely user friendly machines resembling the traditional ones.
Pneumatic presses neither carry the nagging issue of oil leakage or any other hassle nor do these require any high maintenance for the components. Moreover the air tubes have a comfortable shelf life of about five years.
One has to be extra cautious while using hydraulic presses as these require a lot of maintenance. A sufficient amount of oil is always required within the machinery to ensure its proper working.
MECHANICS
Pneumatic Presses
Pneumatic presses are basically guided by the manipulation of pressurized air. Technically, the air is pushed into the tube generating air pressure within it and hence, making the press move downwards. As a particular press stroke comes to an end simultaneously, the air too gets evacuated through valves. Finally, after the stroke is complete, the mechanical springs make the pump move back to the top again.Hydraulic Presses
Hydraulic presses like any other hydraulic machinery works on the fundamentals of liquids. It is so done that a piston is pressed into the chamber making the oil or the liquid to shift its position. Now as the chamber is sealed, the oil exudes pressure on the baseplate making it move downwards.

Hydraulic Presses
Hydraulic presses are extremely reliable and can produce a huge amount of pressing tonnage. These presses are perfect for hydroforming wherein a metal is shaped using a liquid agent because the slow movement of hydraulic presses provides ample amount of time for the metal to gain shape.One has to be extra cautious while using hydraulic presses as these require a lot of maintenance. A sufficient amount of oil is always required within the machinery to ensure its proper working.
