If you are a company that uses benchtop presses there are several things to consider in order to make a purchase that reflects the true needs of your business.

1. Does your manufacturing process deal in high volumes?


2. Since power supplies are separate considerations, what type of power supplies (if any at all!) is available for the desktop hydraulic press in question?


3. What kind of precision and attention to detail are you looking for in your manufacturing operation?

Now lets take a look at some of the options available and see if we can't narrow down your choices:

Arbor Press
These are hand operated presses. They are the simplest and least complicated of hydraulic presses. If you have low tonnage needs these are great inexpensive choices. An additional benefit with arbor presses is they do not need a power source - at least not an external one. Of course, the downside of this is they are low volume presses.

Air/Oil/Booster Press
These are great middle tier presses, and usually have a maximum output of around ten tons.

These don't really have hydraulic power unit, which excludes them from high volume applications, but the side benefit is they often work with 110V single phase electrical systems and a standard shop air compressor.

Compared to arbor presses, air/oil presses tend to be a bit more user-friendly. They also are larger and can have safety equipment also attached to the machine.

On the downside, there are hydraulic press maintenance issues at times with an air/oil press. A majority of the booster presses only allow two hand control and has simple electrical relays which means that integrating other equipment a real pain.

Straight Hydraulic Presses
These presses can perform complete pressing force anywhere in the range of the stroke and can perform various sut heights which means you can use multiple dies. This fact alone means that hydraulic benchtop presses are perfect for a variety of applications.

The other great thing about a straight hydraulic press is the plethora of controller options. Basic relays (as used with the Booster Press) can be used, but much more sophisticated controls can also be used. Controls like PLC's and PC. Operator interfaces are also great additions which speed job setup time and can store job settings. The wide array of settings of hydraulic presses make them almost as much control as the much vaunted electromechanical presses.

Electromechanical Press
These presses utilize very sophisticated control systems which allow for ultra high precision capabilities and performance. Because they used closed loop position and elaborate force control these are used mostly in research fields, labs, etc.

User input, adjustments, and special settings can be performed in an almost infinite number of ways. This makes the electromechanical press one of the most flexible and useful presses out there today.

When choosing a hydraulic press, reviewing the three original questions at the beginning of this article is important. Really think about the needs and requirements of your shop before making an investment. From simple (arbor press) to complex (electromechanical press), benchtop presses will continue to play an integral part in light manufacturing, assembly processes, and lab environments.
