Hydraulic presses are powerful machines that utilize liquid to generate incredible force. A hydraulic pump moves oil through its system into an oil cylinder for pressurizing against an opposing metal piston or ram.

Put the sheet of metal you intend to use into the die, with a pad of flexane covering it. Pump the arm of the hydraulic jack to advance the lower platen, forcing the metal into the die.


Hydraulic presses are essential tools for metalsmiths. Used correctly, it can help bend sheet metal into shape or even punch and coin it, as well as create hollow forms for jewelry or other projects. However, mastering this process without proper training may take some effort but is well worth your while!

Hydraulic presses come in various varieties to meet different needs. A mechanical press uses an external motor to operate its hydraulic pressure; these machines tend to be used for larger, heavier applications as well as stamping or bending materials used by automotive or furniture industries.

Hydraform presses use two dies to form metal objects. They provide a relatively new technique that enables complex shapes out of sheet metal to be created quickly and efficiently; making this system ideal for producing large and complex parts manually.

Hydraulic presses offer another effective means of creating wrought iron or steel molds for casting products of your own design, offering greater precision than plaster or clay methods typically employed in metalsmithing industries. Such molds can be used to cast anything from small trays to industrial equipment parts.

Step one of creating a die for a hydraulic press involves cutting a piece of metal large enough to cover the female die, plus extra material all around - this allows you to reuse some parts later for castings. Next, lubricate both your die and container walls prior to pouring your Devcon into it - this will prevent cracking or shattering during pressing processes.

For smaller, more detailed projects, pancake or impression dies may be the ideal tool. Crafted of hardened steel, they leave an impression-shaped pattern on annealed metal surfaces when used for creating finished pendants, earrings and rings. Pancake dies can also be useful when creating bracelet links and bales; often using hubs from hub machines that once existed within the jewelry industry as sources.


An hydraulic press can be an immensely powerful tool, but misused it can become dangerous. A hydraulic press uses two cylinders to generate pressure which compresses a workpiece between an upper die and lower die, whereupon its desired shape is formed - including bending, drawing, punching, coining or extrusion operations.

Shane Wighton recently attempted to use a 3D printed form to bend sheet metal, with mixed results. At first, his printed forms shattered under pressure from a hydraulic press; but through some design revisions and switching out resin types for stronger ones he eventually managed to make this method reliable enough for producing up to 100 parts at a time.

Hydraulic presses can be used to craft jewelry designs ranging from simple shapes to complex forms, from intricate forms. To begin creating your piece, start by drawing a scaled-down sketch of what you would like to create; this will give an idea of the size of your finished product. Next step should be selecting an appropriate die for your project; there are various kinds available - forging press dies can be costly to produce due to needing special steel that must be heat treated and rough machined before they can be put into production.

Shearing metal can also be an effective method of creating intricate reliefs and depth in jewelry designs, or you can use pancake and impression dies to produce shapes ready for turning or addition into designs.

Forging using a hydraulic press is more complex than stamping or bending, yet more cost-efficient and accurate. Calibration must also be properly performed prior to beginning production.


Hydraulic presses can be an efficient tool for many tasks, including metal shaping. Jewelers have found them particularly helpful for creating bracelet and ring blanks quickly and efficiently with this machine from Rio Grande; its use has even become popular with toolmakers at Bonny Doon who demonstrate how to use 20-ton hydraulic presses with bracelet and ring blanking dies made out of flexibleane for creating bracelet and ring blanks quickly and efficiently. In this video by Rio Grande they demonstrate using 20-ton hydraulic press with blanking dies made out of flexibleane in conjunction with Bonny Doon toolmakers then shows how these blanks become completed products such as finished cuffs or rings from unfinished blanks made out of flexane material by Bonny Doon toolmakers also demonstrate.

Conforming dies are created from models of the form you want to reproduce. You can make one out of wax, plaster, wood or plexiglass; extreme accuracy should be maintained for its design. Small details cannot be replicated by conforming dies but instead through chasing.

Flexane material placed inside a steel pipe is used as a matrix with various punches to form various types of shapes. Flexane is an elastic rubberlike urethane material that won't compress but rather forms itself around whatever form is created, providing endless use. Flexane has also proven useful as an embossing material!

Once the matrix die is prepared, its next step should be creating a brass or steel plate with an outline cut into it; this becomes Part B of the matrix die. A 3/8 inch thick piece of plexiglass or masonite cut to size becomes Part C for conforming die. Parts B and C should then be placed over one another with glue or doublestick tape securely holding together their respective mating surfaces.

Before using conforming dies, ensure they are clean and well lubricated. Lubrication helps the dies release metal more easily by keeping them from sticking together; silicone oil works best here although water-based release agents might also do the trick. Also make sure shearing dies are properly greased - particularly where plates impede each other - for smooth performance.

Hydraulic fluid

Hydraulic presses are powerful machines that utilize liquid as energy transfer medium. Their primary use is cutting metal into different shapes or shaping it to specific forms, with easy operation making production quicker while meeting project requirements by altering pressure, stroke speed and process position settings to meet them.

Hydraulic presses are widely used to manufacture metal parts, from small deep drawn stainless steel parts and aerospace components, to smaller deep drawn pieces made of aluminum and plastics. Hydraulic presses can quickly produce multiple shapes at an incredibly rapid rate while still handling larger and more complex parts that require considerable force for formation. They're even adjustable so as to work with multiple materials - aluminum being one such common choice while special hydraulic presses exist that specialize in fabricating plastic parts.

For creating dies for hydraulic presses, selecting the appropriate material is of utmost importance. Lexan, which is made from high-density polycarbonate that resists shattering and also has lower costs compared to other plastic materials, makes an excellent choice.

Hydraulic die forming involves pressing sheet metal into a die, similar to hammer forming but much faster and with much less force required. There are two general categories of dies used for hydraulic die forming: non-conforming dies that have only one shape while conforming dies have mating positive and negative shapes that meet.

Hydraulic forging presses are impressive machines capable of creating massive amounts of pressure. Used to manufacture titanium/aluminum alloy forgings for various industries, they're marvels of engineering.

Hydraulic forging presses contain various parts, such as a hydraulic cylinder, oil tank and pressure gauge. The hydraulic cylinder connects directly to a pressure plate via pipe and applies unidirectional stroke force that generates pressure by applying unidirectional stroke force; additionally it contains a plunger that can move back and forth to create force when pressing metal; this pressure generated is transferred via hydraulic fluid to pressurize ram. Furthermore, each hydraulic system includes safety doors, limit switches, manual control valves and relief valves as well as safety doors /limit switches /manual control valves/relief valves /relief valves/relief valves/relief valves etc.
