Hydraulic presses are essential workshop tools, making light work of flattening and crushing things. Furthermore, you could even turn them into an additional source of revenue by crushing old oil filters for recycling.

Hydraulic Power has long been recognized for their videos of machines crushing things, but this video takes it one step further: red-hot nickel balls can't withstand the power of this hydraulic press!

Why is it so hot?

Hydraulic press machines have many applications in various industries, from metal forming to crushing objects. But they can be dangerous if used incorrectly; therefore it is important to understand their function and safe practices for using them.

Hydraulic presses come in many varieties, yet all operate similarly. Each hydraulic press is powered by a hydraulic pump - either manual, pneumatic, or electric depending on its application and press size - that creates a fixed pressure that determines its force, usually measured in tons. When pressure reaches its limit it forces an expanding pressing cylinder to extend which then contacts material being pressed with controlled force from its pump.

As soon as the hydraulic cylinder applies pressure to material, heat builds up. This is due to energy being converted from applied energy into kinetic and then thermal energy; which transfers through its piston into working fluid causing heat transference through piston and working fluid system requiring proper insulation of this portion of hydraulic system.

Hydraulic presses typically utilize oil for their liquid component; however, water or an emulsion made up of both are also acceptable options. This liquid serves to transmit pressurized force while keeping machine parts lubricated; its characteristics must include low compressibility and high viscosity while being non-corrosive.

Hydraulic presses are most often associated with manufacturing, but they have applications across a variety of industries - agriculture for instance uses one for repairs and maintenance on large farm equipment.

Hydraulic presses can also be utilized in sword-making by heating steel to an extremely high temperature before using the press to form metal into their desired shapes.

Recently, Vuohensilta of the Hydraulic Press Channel posted a video demonstrating his use of his hydraulic press to crush three red-hot nickel balls that have become signature objects of another popular YouTube channel, carsandwater, known for pitting red-hot nickel balls against all sorts of objects before crushing them with his hydraulic press.

How does it happen?

Hydraulic presses utilize mechanical force to produce large amounts of pressure, making them essential to many industrial processes. From shaping machine components to crushing waste material and compacting it down into compacted piles, hydraulic presses have an extensive role within manufacturing industries worldwide.

Pascal's law forms the core principles of how hydraulic presses function. According to this law, pressure within incompressible fluid remains constant over its surface area. To increase force generation, hydraulic systems often utilize oil as an agent because its viscosity helps distribute pressure evenly over its surface area.

As hydraulic fluid passes through its system, it accumulates thermal energy that is then transmitted to the work piece being compressed. This thermal energy causes metal to heat up, leading to frictional heating that eventually causes its atoms to rub against each other - leading to deformed metal formation.

Since metal's atoms are colliding so rapidly with each other, they release an enormous amount of energy, which heats it when being compressed. Therefore, controlling force and position of impact is essential so as not to overheat the metal and create an explosion of heat.

Even without access to a hydraulic press, it's still possible to demonstrate this phenomenon using everyday household items. Bending a paper clip back and forth can cause it to heat up as its atoms rub against each other quickly.

Hydraulic Press Channel have taken their hydraulic press crushing to an entirely different level by heating steel and using their thermal camera to record what happened as various items met their demise in a pancaked heap of steel.

What can we do about it?

Hydraulic presses require precise control to create parts with just the right amount of kinetic energy, otherwise parts won't have enough force to do their jobs while too much will damage or injure their operator.

There are a number of things you can do to optimize the performance of your hydraulic press, including using a cushion that absorbs some of the impact energy before it transfers it to the work piece - this reduces both time and energy spent forming parts while still being able to apply enough force. Furthermore, pressure, impact speed, process position changes can help create larger more complex parts with reduced effort.

As part of your hydraulic press machine maintenance routine, make sure the material being pressed is of manageable size and has its limit switch adjusted correctly in order to prevent excess pressure being applied directly onto your material or causing machine malfunction.

If you want a fun way to see how a hydraulic press works, check out The Hydraulic Press Channel on YouTube. Finnish workshop owner Lauri Vuohensilta crushes various objects using his 140-ton press, garnering significant fame with its unexpected results and hilarious sense of humor from Vuohensilta himself. This channel has gained great traction.

Hydraulic presses may be best known for their viral internet fame, but they play an important role in numerous industrial processes. From shaping and creating machinery components to compacting waste and garbage, hydraulic presses play an integral role in many production processes. Furthermore, hydraulic presses are much less expensive than traditional mechanical processes due to not requiring as many moving parts; making them an attractive option for companies looking to maximize production efficiency while decreasing costs.

Is it dangerous?

Hydraulic presses themselves aren't necessarily dangerous machines; however, their operation can become hazardous if workers fail to observe proper safety precautions when operating them. This includes making sure it is in good working order and scheduling regular maintenance checks for it; otherwise it could experience critical failures which result in serious bodily harm or worse.

Oil leaks are a frequent problem in hydraulic systems. To minimize oil leakage and ensure worker safety, employees should regularly inspect presses for leaks and keep the area clean in order to avoid contamination. A leaky piston oil seal can lead to loss of pressure due to overfilled oil reservoirs, contaminated check balls or loose piston packing; in order to stop this from happening again it's essential they inspect regularly the press for signs of oil leaks before tightening or replacing packing as required.

Hydraulic presses present several hazards to their users, including physical injuries such as burns and sprains as well as chemical hazards arising from contact with lubricants and hydraulic fluid. Workers should always wear personal protective equipment (PPE) when operating these machines, including gloves, safety glasses and earplugs; training on safe machine operation should also be provided, along with daily inspections to ensure it remains in proper working order.

Note that hydraulic presses require significant force to crush objects, which results in thermal energy that is felt by anyone nearby the machine. This thermal energy can be intense and cause severe injuries without proper PPE. When used to crush metal, its shrapnel may hit those nearby as shattering occurs; without sufficient protection such as shields and safety measures in place, projectiles could even launch out from within the press, injuring workers nearby.
