Hydraulic presses are powerful machines often employed for metal-forming. Comprised of a pump, endplates and hydraulic cylinder, these presses offer great precision when used effectively.

Use pancake dies to craft jewelry scale shapes such as earrings, rings and bracelet links with precision and impressive patterns. Or try impression dies for intricate patterns.


Hydraulic presses are essential tools in any serious metalsmith's workshop, as their simple design enables you to shape precious metal into various shapes and textures by pushing and shaping sheet metal into molds. While commercial presses may cost over $1,000, you can build one for under $50 with some elbow grease.

Hydraulic presses consist of a sturdy frame in which is inserted a hydraulic ram powered by either a manual or electric hydraulic pump, depending on application and press size. When activated, this creates a fixed pressure measured in tons; pushing against your metal piece is done so with this force.

Pressing metal pieces with various gauges of metal has an impact on their final look, with thicker gauges yielding more solid pieces while thinner gauges will pick up less detail.

Most metalsmiths rely on hydraulic presses to bend and shape sheet metal, but the press can also be used for other tasks like forming wire into rings, creating curves in metal surfaces or creating impressions in metal pieces.

Hydraulic presses come in all sizes and configurations. Some are designed for ease of access in tight spaces while others feature larger beds with wider tables for greater capacity. There are even models designed specifically to act as tables or jigs so users can work on multiple pieces at the same time.

To create your own hydraulic jewelry press, cut all required metal parts to their appropriate sizes and weld them together before bolting them together to assemble your frame. Some people also opt to create their hydraulic press using threaded stock and nuts instead of welding, though this method may be less secure and durable than its welded equivalent.

Hydraulic Pump

The hydraulic press is an invaluable tool for shaping, embossing and stamping metal into various forms. In this five-day course, students will learn to use it for creating exciting forms in jewelry and small vessels as well as mastering tools and techniques used for etching stamping silhouette forming and silhouette etching. Furthermore, safety and maintenance will also be covered. While this workshop is tailored toward beginners, experienced users will also find this workshop beneficial in exploring this multipurpose tool.

Hydraulic pumps are mechanisms designed to transport hydraulic fluid from one location to the next. Most often used in hydraulic machinery applications, hydraulic pumps produce energy and pressure by pushing on pistons inside a fluid-filled cylinder - this basic mechanism makes hydraulics so invaluable in construction as well as automotive manufacturing applications.

Hydraulic pumps can either be positive or negative displacement pumps depending on the number of vanes present on their rotor. Positive displacement pumps feature flexible vanes which sweep liquid up into their cavities; once inside, this liquid passes through several internal components before eventually exiting through their discharge port to generate mechanical power.

Negative displacement pumps feature a solid core and are more energy-efficient than positive displacement pumps. Their camshaft pushes on either an external plunger or internal piston to generate mechanical power; in many instances, these pumps can generate up to 10,000 PSI of pressure!

Understanding the differences among various hydraulic pumps is crucial to professionals, enabling them to choose one most suited to their needs. For example, multiport pumps make complex operations much simpler, making it simpler to achieve your results without needing to reposition equipment every time you want a change.

Hydraulic systems produce an array of sounds, making it important to recognize them in order to identify when something goes awry with your machinery. Cavitation may cause an audible growl while worn bearings could produce rattles or screeches indicating you require professional services to reduce further damage to your machine.

Hydraulic Hose

Jewelers use hydraulic presses as an indispensable tool for shaping precious metal into intricate forms and textures. A powerful machine, it requires careful use to avoid damage to either itself or to its workpiece. Unlike vises, hydraulic presses generate immense pressure that applies evenly across their plate surface allowing jewelers to press multiple layers of metal simultaneously into intricate forms with intricate textures, textures, or patterns.

To ensure your press can withstand the massive amounts of pressure it will be subjected to, purchasing high-quality hydraulic hose is essential. The ideal type is spiral reinforced synthetic rubber hose; this features an inner tube made from oil-resistant synthetic rubber reinforced by wire braid or steel helix reinforcement and an outer cover designed to resist abrasion, chemicals, voltage spikes, mechanical stress and extreme temperatures - ideal for jewelry presses! To guarantee success when selecting hydraulic hose for jewelry presses it should have the following qualities.

Likewise, the hose has field-attachable couplings to connect its ends. These couplings may either be screw-together or clamp-type and may be attached by turning their outer shell over the outside diameter (OD) of the hose or by clamping over its helix - in either case connecting via two or four bolts and nuts that clamp over its helix. Screw-together couplings connect using screwing in an insert into their coupling shell while clamp-type couplings use bolts and nuts that clamp over its outer shell; while clamp-type couplings fasten over its helix for easier assembly or by turning its outer shell over its outside diameter (OD), making connections easy compared with traditional methods requiring bolting up to its ends.

When choosing a hose, take into account both its material composition and compatibility with the hydraulic fluid used in your system. Some materials can be chemically incompatible, so be sure to consult a compatibility chart when making your selection. In addition, its working pressure must meet expected system pressure - any spikes above this published value can shorten its life significantly.

Hydraulic Cylinder

A cylinder is a steel barrel used to store hydraulic fluid. For proper functioning, its walls must be thick enough to withstand pressure without leaking; designers will select materials according to each application - for instance those being used in extreme environments may require specially-made seals to withstand high temperatures while vibration-resistant models also exist.

A piston rod sits at the centre of a cylinder and is propelled by hydraulic fluid, creating reciprocating motion in it. To ensure no hydraulic fluid passes over this piston during its oscillations, special seals, usually U-shaped in shape and of different sizes are fitted onto it depending on cylinder size and its intended use.

Seals made of polyurethane can be specifically tailored for each hydraulic system based on several factors; such as its temperature. Seals used in extremely hot environments may need seals that won't melt while those used in cold conditions need durable seals that won't harden or crack under pressure.

Cylinder designs also consider the type of hydraulic fluid they will utilize. Different oil types offer distinct benefits; one might work at higher temperatures while others can withstand various working environments.

A quality hydraulic cylinder will have two ports that provide easy connection to pumps and valves, often via screwed connections; sometimes flanged ones may also be used. To ensure correct positioning of its head on either end of its piston rod threading can also help.
