Richard Sweetman teaches how to use a hydraulic press to form exciting dimensional forms from metal. You will also gain skills for embossing and creating silhouette dies for vessels and boxes.

Over time, hydraulic presses require rebuilding or upgrading to remain efficient and safe to operate. These improvements increase their overall effectiveness and safety of operation.


Hydraulic presses rely on hydraulic cylinders to generate compressive force, making them useful in applications like crushing, straightening and moulding metal materials. Mechanical presses use much larger amounts of pressure in smaller spaces compared to hydraulic ones; moreover they offer much wider applications including deep draws, shell reductions, urethane bulging and forming.

At this workshop, you will discover how to use a basic hydraulic press to emboss, texture and shape metal. Additionally, you'll learn how to form three-dimensional shapes using silhouette dies as guides; create chic pendant forms from these; bend thin metal strips into rings, bracelets or beads for jewelry making.

Hydraulic forming is an efficient and economical method of producing jewelry and metal work with multiple shapes and sizes, including bracelets, rings, beads and vessels. Hydraulic forming allows you to craft complex bracelets quickly while maintaining uniformity across your designs.

Hydraulic press-forming may seem complicated at first, but with practice you will quickly master this tool and become adept at using it in your work. Richard Sweetman will show you all of the fundamentals involved with using one to craft textures and sculptural forms in your designs.

Your home can become your workshop by simply assembling some common household equipment into a hydraulic press. A basic model includes metal plates, four lengths of round stock steel and some springs connected by metal rods powered by an inexpensive standard hydraulic bottle jack - creating a sturdy yet simple-to-operate and cost-effective machine which will increase production capacity while speeding up work time. A DIY enthusiast or metalworker without the budget for an industrial sized press may find this an enjoyable project; small hydraulic presses can often be built for under $100 which provides enough force for working metal sheets!


Hydraulic presses are powerful tools for shaping and forming metal. Their precise control ensures consistent results with reduced production time while increasing design flexibility and form flexibility. Hydraulic presses utilize pumps, cylinders and valves to apply high pressure forces on metal items, from small handheld tools up to commercial machines capable of handling thousands of tons.

At the core of any hydraulic press lies its hydraulic cylinder. You'll find them both on large industrial machines as well as smaller handheld models designed specifically for jewelers' use. All hydraulic cylinders contain oil as a hydraulic medium to transmit force from their respective hydraulic system to an end user.

There are various kinds of hydraulic cylinders designed to produce specific amounts of force for different jobs. Smaller ones, like handheld presses' miniature versions, generally produce less force. Cylinders may also be mounted either externally to the machine itself or held within its frame - depending on which you need them for.

A hydraulic press' drive system is also an integral element. There are two primary systems - pump direct and pump-accumulator. Pump direct uses direct power delivery from its source to its hydraulic cylinder while pump-accumulator uses an accumulator to store high pressure working fluid and provide safety overflow.

As well as its hydraulic cylinders and drive system, a hydraulic press requires various accessories, such as a control panel, hydraulic hoses, valve box and emergency shut off valve. All parts should be closely inspected during maintenance to ensure their condition and all settings remain secure.

The hydraulic press is an invaluable tool in jewelry-making, offering endless possibilities. In this course, jewelry designer Melissa Muir teaches how to use one for embossing and forming metal shapes using pancake dies as starting points before moving on to create stylish pierced silhouette forms and bracelets with silhouette dies before instructing students how to work with anticlastic and synclastic forming techniques.


Hydraulic presses are versatile machines that combine mechanical and hydraulic power to exert compression against an anvil or die, creating compressive force against it and shaping metal into various shapes such as forging, clinching, moulding and punching. Their compact yet versatile designs have made it the go-to option in a wide variety of manufacturing applications.

An industrial hydraulic press can be extremely heavy and expensive, while homemade models can be assembled using a basic bottle jack and can generate up to 20 tons of force. Following a basic parts diagram as guidance, machinists cut and weld steel plates together into the frame of the hydraulic press before threading two washers and nuts on threaded stock pieces to complete it.

Die for the hydraulic press are made out of pieces of masonite or other materials which match the desired product shape, such as silhouette dies Richard uses for creating pendant and earring sets, or more complex ones cast with male/female conforming metal shapes, pourable epoxy-steel or pourable epoxy. When producing runs of 10 or more items it makes sense to invest in conforming dies that can withstand hard and long-term use.

For pressing, rubber inserts are placed into the die above its negative space to act as soft cushioned support, protecting it from being crushed under hydraulic pressure. Next, material to be inserted is annealed and then secured to the die with glue in order to stop any movement during pressing.

Hydraulic presses are powered by pumps connected to levers or cranks that regulate hydraulic pressure being applied to their dies, with each movement of their ram allowing for control over how much pressure is being applied; as its position changes, force on workpiece increases or decreases, providing precise tonnage adjustments based on each job; this gives an advantage over traditional metal forming methods like drop hammers that cannot be customized as effectively.


Hydraulic machines generate tremendous pressure, making them invaluable tools in many heavy-duty applications. But for all their power and complexity, hydraulic machines still require routine inspections, fluid checks and component replacement to stay operating safely and optimally - this prevents system failure as well as costly repairs down the line.

At the core of any maintenance process is making sure your press is equipped with an effective safety system, including a failsafe locking mechanism that will immediately stop its operations if an accident happens and protect workers from injury. Furthermore, this system should monitor force to within specifications as well as being installed in an isolated area so operators only gain access during scheduled downtime periods.

One essential step of proper maintenance for presses is ensuring the hydraulic system has enough oil, free from contamination. This is especially crucial when operating at higher temperatures which may accelerate degradation of fluid quality and cause system components to deteriorate faster. High-quality hydraulic oil with low viscosity is recommended to limit wear and extend press life.

Knocking noises are a frequent annoyance in hydraulic presses, often caused by cavitation due to air in the hydraulic fluid. Cavitation can damage seals, overheat the system and reduce lubrication levels; to mitigate risk and prevent this situation, always inspect your press's ram for leaks, O ring seals and guided platens as well as its guided platens, hose end fittings and hydraulic lines for leakage or overheating issues.

No matter if your press frame is constructed from welded metal or tie-rod, its attachment bolts should be checked periodically to ensure they are tightened to the appropriate torque. Many presses feature baseline marks which serve as visual cues when tightening needs to be adjusted or tightening should occur again. Furthermore, you should keep an eye out for loose fasteners on bolster plates and tie-rod pretensioning nuts that need tightening again.
