How to Select Hydraulic Presses

Locating and purchasing the appropriate hydraulic press machine can increase production efficiency while simultaneously decreasing upfront and operational costs. Therefore, it is crucial that buyers understand optimal usage, pricing and the various types of hydraulic presses before making their purchase decision.

Selecting the ideal press tonnage can often be a matter of guesswork; but with a hydraulic press you can quickly and accurately tune tonnage settings to suit whatever job is at hand.

Consider Your Needs

Before purchasing a hydraulic press, it's essential to carefully consider your individual needs. This will help determine its type, size, model, features and use. Also keep in mind how the machine will be utilized and whether there's room for expansion if production requirements change in the future.

Hydraulic presses offer many capabilities, from bending, blanking, drawing, forming, molding and punching, to punching. Some press types require specific capabilities while others can perform them all. When choosing a hydraulic press it is also essential to consider both its capabilities as well as the workpiece type being processed - as this will determine how much pressure will be necessary. Furthermore, selecting one with appropriate return capabilities such as position or force return must also be considered; similarly it is imperative that poor quality equipment causes costly downtime due to leaks or other problems.

Know the Tonnage Requirements

Modern hydraulic presses are fast, reliable and offer more precise tonnage control throughout their press stroke than mechanical ones. Furthermore, they're less costly and easier to maintain, making them more attractive than comparable mechanical models in terms of both cost and upkeep.

The tonnage requirement of a hydraulic press will depend on your field of work. Ideally, you should opt for one with plenty of reserve tonnage capacity in case your needs change in the future; this will guarantee you have enough power for every task at hand without overtaxing or damaging your machine.

Hydraulic presses are typically comprised of off-the-shelf components that are fully lubricated by pressurized oil flow, but their quality determines performance and lifespan of your machine. Poor quality components may lead to severe oil leakage. Therefore, ensure you purchase a hydraulic press with high quality cylinders and molds so as to reduce costly repairs in the future.

Know the Type of Workpiece

Workpiece type will play an essential part in selecting a hydraulic press. Different metalworking processes may necessitate different sizes and types of presses; an automotive shop, for instance, may need one capable of handling tonnages of 20 tons or greater for pressing bearings, U joints and wheel bearings.

Hydraulic presses use a pump and hollow cylinder to generate power by increasing pressure within their working fluid reservoir cylinder - typically water but also an emulsion of oil and water can be used.

Mechanical presses lack the versatility that hydraulic presses offer; therefore they're used for only specific jobs like deep draws or shell reductions. Instead, hydraulic presses offer greater versatility as they're often employed for applications like deep draws, shell reductions, urethane bulging, forming, blank and pierce, stake punching press fitting and straightening; not forgetting they're much quieter.

Know the Safety Requirements

As part of selecting a suitable hydraulic press, make sure that it has all of the safety features necessary. This includes an emergency locking system which protects workers in case of machine malfunction or failure - this is especially important given that hydraulic systems can often be complex systems which increase their likelihood for malfunction.

Dwell capabilities are an integral component of many processes, such as bulge forming and impression forming. Dwell systems enable machines to meet target forces for an extended period of time by creating pressure systems adapted specifically to that force, keeping that force constant over time. As each machine builder offers different electrical and hydraulic options, it is vital that your needs are communicated upfront to them.

Hydraulic presses require routine inspection and maintenance in order to protect critical areas of the machine, keeping lubricants fresh for smooth operations and reducing friction. Furthermore, proper maintenance helps avoid overheating caused by equipment damage or insufficient lubrication.
