Maintaining your hydraulic press in top working condition is of utmost importance in order to avoid accidents and complete machine failure.

Daily inspection of a hydraulic press and its safety equipment is absolutely vital to avoid potentially hazardous situations such as damaged cylinder seals and ensure that the appropriate pressure level is achieved.


Hydraulic presses use Pascal's principle to generate enormous forces, and are an indispensable part of many machine shop applications. They're great at accomplishing tasks other machines cannot, such as bending, forming, shearing, punching and drawing metal; but like any piece of machinery they require maintenance in order to function as expected.

Presses depend on three elements for optimal operation: mechanicals, hydraulics, and electrical/control elements. If any one or more of these areas fail to perform effectively, it puts the entire machine at risk.

Hydraulic presses consist of two connected cylinders filled with fluid connected by pistons. An operator can use hydraulic pressure to control which cylinder the piston resides in, with force from their slave cylinder pushing fluid into master cylinder to equalize pressure between both cylinders and any material between them - an essential power for forging, metalworking, and other industrial processes.

To allow a hydraulic press to function at high speeds, there are special pumps and valves installed into its control circuit that help facilitate rapid opening/closing cycles during return stroke and work stroke, speeding up cycle times. When contact is made between ram and work-piece, this allows more rapid penetration. When this occurs, control circuit opens large volume, low pressure pump to reservoir while closing small volume, high pressure pump back onto cylinder, readying for another cycle.

Hydraulic presses offer several distinct advantages over mechanical presses. Not only can they operate with lower loads than mechanical presses, but their pressure levels can be easily adjusted down, eliminating overpressurization risks that damage hoses and seals as well as cause mechanical failure in pumps, motors, cylinders, valve plates or valve plates. Furthermore, lack of impact shock vibration prolongs tool lifespan by reducing wear on them.

Safety Devices

Hydraulic presses are essential pieces of equipment in many industrial settings. Machine shops frequently utilize them to compress, cut or punch material for punching holes in boxes or molds and straighten surfaces, drill straighten and mold products. But these presses pose significant danger to workers if not operated with safety in mind - which is why machine shop owners or operators must create an environment conducive to safe use when employing hydraulic presses.

Modern hydraulic presses come equipped with OSHA-required safety devices, such as interlocks, guards, electro-sensitive and optoelectronic devices, emergency stop systems and redundant systems designed to protect them and their operators from expensive damages. However, their effectiveness depends upon proper installation and usage. A machine shop owner or operator must also conduct periodic maintenance inspections of the hydraulic press to make sure all safety functions are working effectively.

Hydraulic presses pose several potential hazards, with crushing and pinching injuries being among the primary concerns. Rams, slides and other components in the machine may crush or pinch body parts with severe injuries or even amputations potentially occurring as a result. Electrical risks also present a major threat as hydraulic presses require electricity for operation - this can result in shocks, burns and fires should the machine not be wired correctly or used/maintained improperly resulting in shocks, burns and fires occurring as a result.

Hydraulic systems contain fluid that could become dangerously explosive if it leaks or ruptures, and their operation often produces noise and vibration which may cause hearing loss, eye damage, or other health concerns in workers nearby.

One effective strategy to lower risks associated with hydraulic presses is educating workers on how to use them safely. This requires making sure all employees receive appropriate training, know where the controls are located on each machine, and know what action should be taken if machine failure or other problems arise. In addition, machine shop owners or operators should encourage workers to report any potential hazards or issues they notice while using hydraulic presses.


Those seeking a heavy-duty machine that can withstand large amounts of force and pressure may find a hydraulic press ideal. These presses can crush metal into various shapes needed for projects, making them versatile across a range of industries - metal fabrication for instance heavily utilizes hydraulic presses as they produce intricate metal pieces which would be difficult to form manually; other industries including manufacturing, construction, waste recycling are all using hydraulic presses too!

Most hydraulic press machines can be tailored to meet your unique requirements, so take the time to make the best purchase decision for you. Tonnage adjustments make it simple to get exactly the amount of power you require for a particular project. In addition, read reviews and ratings so you know what others have experienced with a particular machine before purchasing one.

Hydraulic presses may be powerful machines, but they're not entirely foolproof. Over time and with heavy use, their parts can wear down, necessitating maintenance or repairs in certain spots. Therefore it is critical that when using one it always adheres to Z142 safety standards for best practice.

One way of ensuring the safety of a hydraulic press is by adding cushioned workpiece support. A rubber mat works to absorb some of the impact energy of each workpiece impact and give servo valves more time to respond before it damages any delicate workpieces.

Alternative solutions may involve installing a separate hydraulic cylinder for cushion. This will minimize how much hydraulic fluid is consumed, saving money on utility bills. If this method is chosen, however, oil changes must be performed regularly and temperatures monitored closely to prevent early wear-and-tear wear of the press system.

Hydraulic presses can be used to compress materials of all sorts, from food and other products to materials used in packaging. Food industry applications for hydraulic presses include compressing food prior to packaging - this makes transportation and storage simpler, as well as increasing shelf life by forcing out air and limiting bacteria growth.


When large amounts of pressure and force are necessary, hydraulic presses are the go-to solution. Many industries rely on these powerful machines for various tasks, including straightening bent shafts, straightening sheet metal panels, compressing unneeded materials and other tasks that demand intense force and pressure.

These machines operate under extreme stress conditions and need regular maintenance to stay operating smoothly. A clean work area, regular lubrication of parts when necessary and removal of debris around the machine are key steps towards ensuring safe functioning of a hydraulic press.

Regular inspection is vitally important when it comes to the ram. Shimming can damage both rams and cylinders and should be addressed as soon as noticed.

Leakage from pump plungers can also be an issue, often caused by loose packing nuts or worn piston seal. If not repaired quickly, this issue could escalate and lead to costly repair bills in the form of lost production and revenue.

Hydraulic systems should have a consistent temperature below 160 degrees Fahrenheit for proper machine operation, Pacific Machinery offers special hydraulic oil that has been filtered to guarantee this. Pacific machinery recommends changing out their oil every 4000 hours or so as doing this will help protect from overheating that could shorten its life and shorten its useful life span.

Record any findings or problems encountered when inspecting a hydraulic press. This will make it easier to keep track of what has been accomplished, should an accident or injury claim arise, and will also serve as an early indicator for repairs or problems that need addressing before becoming more costly repairs later on. Downtime from a hydraulic press can be extremely expensive for companies that rely on it, leading to substantial revenue loss for these organizations.
