No matter your experience level with metalsmithing, a hydraulic press is an invaluable asset in the studio. While you could purchase one commercially for around $1,000, making one yourself using bolt together frames could cost less than $50 and still do the trick!

The Hydraulic Press Channel is an acclaimed YouTube channel dedicated to crushing objects with hydraulic presses. With over 2.2 million subscribers, this channel offers the latest crushing techniques!


Hydraulic presses are industrial machines that utilize fluid pressure generation to form and shape materials, serving as workhorses in manufacturing but adaptable enough for small workshops as well. While mechanical and pneumatic presses use compressed air for dynamic movement, hydraulic presses use liquid to generate force which drives their rams and dies - unlike mechanical and pneumatic models which rely on compressed air alone for this force production.

There are various kinds of hydraulic presses, each designed for specific uses. H-frame hydraulic presses, for instance, are best suited for laminating or moving material between dies - hence their name! Lab hydraulic presses may have one specific purpose like impressing polymers onto surfaces; others like pourable epoxy-steel molds for bracelet fabrication may even feature.

If you want to use a hydraulic press for jewelry production, search for features that meet your specific needs. For instance, some presses offer adjustable stroke depth that enables users to control how close the ram comes to material during each push and dwell timers that regulate how long each stroke lasts.

When your project requires precision, hydraulic presses are your ideal solution. Their fluid pressure cannot be replicated by mechanical or pneumatic presses, and their ability to quickly adjust tonnage makes them perfect for precision work.

As an example, using a hydraulic press can make creating identical bangles much faster and more precise than using traditional tools such as hammer and punch. You can also use one for creating unique textures in metal such as roller printing or etching. To build one yourself, start by collecting scrap metal or junkyard steel pieces known as U channels or I channels from junkyards; you will need four of each longer than the height of your hydraulic jack or ram before threading washers and nuts onto each end of each threaded stock piece before bolting it all together using wrench.

Pancake Die

Basic hydraulic presses consist of a solid steel frame fitted with an hydraulic ram, used to push one die against another. They cost a fraction of what commercial presses cost and are relatively straightforward to construct, although you may require extra parts in order for your setup to function smoothly.

The pancake die is an invaluable asset when working with a hydraulic press, as it greatly speeds up the process of creating metal shapes faster than using hand tools alone. A pancake die works by sandwiching metal between its silhouette die and urethane sheet; when exposed to pressure from its ram, this expands and forms the shape of your metal around its exterior surface.

Silhouette dies come in various shapes and sizes, such as circles, triangles, diamonds, teardrops, crescent moons and hearts. If your design involves more precise curves or tighter radius lines, more specialized dies may be required to produce the design you envision. Some metal smiths use cast male/female conforming dies made of either metal or pourable epoxy-steel to achieve this level of detail and tight curves with hydraulic press presses.

Pancake dies can help make cutting shapes from nonferrous metal such as copper, brass and silver easier and save time in making decorative jewelry designs. When using such metal cutting dies in your press, always ensure the metal has been annealed prior to cutting as well as cleaning your die.

Melissa Muir offers an excellent introductory class called Make the Most of Your Hydraulic Press that provides beginners with all they need to start using a hydraulic press for metal forming. In this class, students learn how to set up and operate their press while crafting an exquisite copper flower pendant using pancake dies; also included is learning how to form 18 gauge flat brass into "puffed up" hearts using pancake dies; punch pierce holes into flat surfaces using punch punching, riveting shapes to create different forms by punching, piercing holes pierced holes pierced holes or riveting shapes onto flat 18 gauge brass for use by Punch Piercing Holes and Riving Shapes!

Rubber Inserts

Like children squeezing play-doh through shapes, hydraulic presses can sculpt metal into whatever form is desired. Compared to pneumatic presses which rely on compressed air for movement, hydraulic presses offer greater pounds-per-square-inch capability and versatility, making them the go-to solution when it comes to shaping metal into complex forms on a large scale.

Daily inspection and maintenance is key to keeping your press operating smoothly, as failing to do so could expose it to major failure or chemical/physical damage. If neglected, press issues could develop that compromise its operation putting its functionality and put its future at risk.

There are various kinds of hydraulic presses designed for specific tasks. H frame presses (commonly referred to as four-column presses) are the most versatile and widely utilized types, featuring numerous dies for straightening, bending, forming, molding punching or cutting metal objects. Other presses such as laminating molding LIM presses which specialize in polymers or embossing are also available as well as smaller models dedicated to specific tasks like embossing or stamping.

Hydraulic presses are complex machines with many moving parts, which makes them vulnerable. Faulty fittings or incorrect oil type can lead to press failure; additionally, overheating poses serious safety concerns that could potentially harm both operator and press alike.

Before using your hydraulic press for jewelry or any other task, it's crucial to gain an in-depth knowledge of its capabilities and characteristics. With proper care and maintenance, a hydraulic press can last many years of productive use.

Homemade hydraulic presses may seem straightforward to construct, but taking time and care in its construction is essential to ensure success. Be sure that the frame can support both the weight of the ram and pressure from metal being pressed under. Likewise, inspect hose fittings regularly and maintain optimal temperatures in your hydraulic fluid supply.

Join Melissa Muir as she introduces you to the fundamental operations of a hydraulic press as you use a pancake die to craft an eye-catching pair of earrings. Next, she explores different techniques for piercing metal shapes, creating custom forms and riveting your pieces for a contemporary finish.


Hydraulic presses for jewelry can be used for various types of metal forming projects, and are easy to learn and create attractive finished pieces. When using such machines it is crucial that appropriate safety procedures are observed - this includes wearing appropriate PPE, following operational instructions carefully, and maintaining it correctly.

Hydraulic presses boast many advantages over mechanical presses in terms of versatility. A single hydraulic press can perform numerous tasks within its tonnage range, such as deep drawing, shell reductions, forming, blanking, piercing, staking, punching and straightening - as well as press fits and ball sizing applications.

An effective hydraulic press can be an indispensable asset to any jeweler at an affordable cost, yet failures of its machinery may cause it to stop functioning as intended and cause production loss or injury to operators or coworkers. Preventive maintenance can significantly decrease these risks.

One of the main issues associated with hydraulic presses is overheating. This may be caused by overuse, lack of lubrication and inadequate temperature controls; to keep it cool it is important to monitor hydraulic pressure so as to not exceed specifications.

Maintaining clean hydraulic lines and connections is also key. Hydraulic lines are susceptible to contamination, leading to heat accumulation that damages seals. Therefore, using an anti-corrosion fluid that has low viscosity should help eliminate contamination while still protecting seals.

Maintaining a hydraulic press in good working condition will extend its lifespan, and regular inspection and maintenance schedules can allow users to detect potential issues before they become severe. A typical maintenance routine should involve visual examination of both ram and die, along with checking O-ring seals on valves and hose end fittings for leakage, while keeping your hydraulic system lubricated regularly with nondetergent hydraulic oil.
