A Buyer's Guide to the Best Hydraulic Presses

Modern-day hydraulic presses are faster, more reliable and versatile. The popularity of hydraulic presses started in the early s when it overtook the use of mechanical presses in production projects. The reason for this was because hydraulic presses are less complicated and are more affordable than mechanical presses. Also, parts of hydraulic presses manufactured by the best companies are durable and easily available thus making it easy to replace. Not to mention, hydraulic presses are effective at doing jobs within their tonnage range.

Getting your hands on the best hydraulic press is not a walk in the park. This isn&#;t the kind of machine that you can just pick from any manufacturer. You need to find one that meets the needs of your company. To help you out, here is a buyer&#;s guide to the best hydraulic presses.

First, Determine Your Company or Business&#;s Needs

What role will a hydraulic press play in your company or business? Answering this question will make it very easy for you to determine the best model, strength, and size of the hydraulic press that suits you. If you intend on buying your first hydraulic press, ensure that you understand its uses and abilities. Don&#;t forget to share these needs with your manufacturer so that they can help you find the best pick.
 

Select Your Press Tonnage

If you are switching from a mechanical press to a hydraulic one, the tonnage requirements will remain the same. But if that&#;s not the case, you need to ask yourself what is the maximum tonnage you might require for any pressing job. As you select your press tonnage, please be informed that most hydraulic presses can be tuned to a lower tonnage.
 

Research on Which hydraulic press is Best for You

Once you know your business&#;s need and ideal press tonnage, you can now start exploring the different types that exist. These varying types can handle different tasks. Here is a list of some of the different types of hydraulic presses;
 


The best type of hydraulic press for your business will depend on the purpose you intend to use it for. Therefore do as much research as possible. Also, consult with a professional manufacturer to help you choose the best type.
 

Consider Accessories for the hydraulic press

The more accessories a hydraulic press has, the more features it offers you with. Some of the accessories you might want to be installed on your hydraulic press include dwell timers, touch screen controls, pressure reversal hydraulic switches, automatic cycling, light curtains and much more. It is essential for you to consider features that improve the usability and productivity of the machine.

Assess the Overall Performance and Maintenance

The further we go in this guide, the closer you get to find the best hydraulic press. Once you have confirmed all the above, it is now time to assess the overall performance and maintenance of a hydraulic press. You should look at the build of the frame as well as its capacity, the diameter of the cylinder, the horsepower, maximum system pressure, and the speed. You should also inquire about the maintenance of the hydraulic presses. How regular should you service the machine and costs associated with maintenance?
 

Make an Informed Decision

As you can see above, choosing the perfect hydraulic press requires tons of research and analysis. This is why you need to partner with a professional vendor such as Press Master when shopping for a hydraulic press. We understand the importance of buying the right machine. It&#;s why we are committed to giving you accurate information, experiences, and reviews. Press Master brings you the best hydraulic presses in the market.

Ideas for automating hydraulic forming press - PLC Talk

Sick has a some sensors specificaly desidn for hydraulic systems but I was thinking just about this force press sensor.

The sensor that you reference in your link is designed to be attached to an IO-Link Network. If you already had an IO-Link network on the machine or any sort of network that an IO-Link master could be connected to then this sensor could be a good choice.

Since you don't even have a PLC we know that you don't have any network right now. For a single sensor, adding a network doesn't make a lot of sense. Several vendors, probably including SICK make these sensors with an analog output which would be wired to an analog input on a PLC. Search ifm, Balluff, Rexroth, Hydac.

Another question is how is the pressure being controlled right now? You mention the operator watching the gage for the right pressure? Is he/she moving a knob on a relief valve to adjust pressure? If you want to do this automatically, then you need a electro-proportional valve. Or is it something like the press is slow enough and the part is squishy enough that the operator watches the gage as the part is compressed and the pressure increases? Then just switch a valve to open the press after the proper reading is reached?

I would not bother with a soft starter if you already have a Y/D starter. Soft starters have a limited number of starts per hour. Especially low cost ones can catch fire if you turn them on and off more often than specified in the manual (not allowing the internals parts to cool down). If you don't always use full speed on the press then a VFD could make sense for noise and energy savings. You still have to worry about starts per hour or get a version with a Safe Torque Off (STO) feature which I would recommend anyway. Then you can leave the mains power to the VFD on and stop the motor safely (so long as you follow the stop circuit in the manual of the VFD).
