Forging is a metalworking process characterized by applying slow pressure to a workpiece under high tension. It differs from drop forging and hammer forging as its contact time with the workpiece is much greater.

Forging is widely employed within industry and artist metalsmiths may use forging techniques on a small scale for forms that cannot be created on stakes. Commercially available equipment can generate hydraulic pressure of up to 3,000,000 lbs/square inch for forging applications.


Forging is a method that uses gradual pressure to shape metal into its desired form, similar to impact forging but using gradual pressure instead of blows. Forging can be performed using both mechanical presses and hydraulic forging presses. Mechanical presses can provide 70 strokes per minute at lower labor costs than impact forging, producing larger pieces than impact forging machines as a result. Hydraulic forging presses are capable of performing over 100 strokes per minute at higher labor costs. Mechanical forging presses produce pieces up to 10 times longer than their mechanical counterparts. A forging press comprises three basic components, which include the frame, ram and hydraulic system. The frame serves as the support structure that houses other parts of the machine while applying pressure onto workpieces; and finally, hydraulic pressure pressurizes working fluid in order to operate forging presses.

Before beginning forging, the first step should be creating a basic die holder from 1" steel. Die holders made from this same material can then be attached with bolts or slides so the dies fit snugly inside it; making sure this happens ensures a high quality finished product and jam-free forging process.

A good die is often created using hard materials such as metal or pourable epoxy-steel, providing for more detail and slower wear and tear during use. Forging can produce stronger metal than traditional machining while simultaneously decreasing metallurgical defects such as porosity and alloy segregation while strengthening corners and radii due to reduced stress on the metal.

Before beginning forging, ensure the metal is clean and dry, then apply a release agent such as Devcon which can be poured onto both molds and dies to keep them from sticking together during forging and will separate easily once forging is finished.


Forged metal components offer superior toughness, durability and lower costs than cast parts. Furthermore, their continuous grain structure can withstand both transverse and axial stresses, but their production requires sophisticated equipment and skilled operators - with hydraulic presses being an efficient method to do just that - by sandwiching hot bar stock between two dies and then applying pressure through both dies to shape it into its final form - this method works great on various materials such as aluminum and steel.

Mechanical forging presses use either a mechanical or hydraulic motor to drive their ram, which then hammers metal. They are widely used in the automotive industry to produce engine and transmission parts with high strength requirements as well as various other products including metal pipes and sheet metal sheets, making these relatively affordable machines that can perform 70 strokes per minute.

Hydraulic forging presses are specifically tailored for open die forging processes. Their large bed and ram can accommodate complex components produced using this method while their incredible amounts of force allow them to serve multiple applications.

As part of designing a hydraulic forging press die, the initial step should be creating a model using Devcon's mold kit. Once created, this model should cover the female die as well as several inches around its edge in order to allow expansion without cracking or shattering during press die forming process. Once it has been created, insert into a pipe, flask or other strong container so as to protect from damage during this step of its creation process.

Wedge clamps can help ensure the clamping force of hydraulic forging press dies is always constant, offering consistent hydraulic forces. Their tapered wedges correspond with those found on forging dies for maximum hydraulic force control, with tightening and unclamping by hand for quick die changes.


Forging is a metalworking process used to change raw steel into its desired shape by applying immense pressure between two dies, creating an impression in its center which then gets filled with hot metal, creating a cavity. Once forged, forging makes pieces stronger and more durable than their original version while making threading and other features simpler to add later on. However, forging can take some time as well as cooling time before further manipulation can occur, and large amounts of heat in contact with dies could potentially cause cracking when done too quickly.

Hydraulic forging, using water pressure as its driving force, is one of the most popular types of forging techniques. Commonly referred to as open die forging, this process works best with flat metals like steel bars and can shape them into various forms. Furthermore, upset forging can use this process to reshape metal into complex bent shapes - the press must be set up correctly so as not to jam the bar into the die; often multiple passes may be necessary until desired shapes have been achieved.

Hydraulic forging presses use microprocessors and digital controls to regulate ram speeds and forces. They're built from special materials with sealed technologies to withstand the extreme conditions found during forging, such as tapered wedges in forging dies which offer self-locking clamping bolts - this helps isolate hydraulic circuits from forging heat loads for increased safety.

The hydraulic press is a formidable machine capable of creating incredible pressure to form metal parts. Some are rated at up to 50,000 tons! Used extensively in manufacturing aircraft parts and other machinery components, its primary use being open die forging due to its slower speed operation than other forging machines.


Forging press dies must withstand immense pressure without deforming or wearing away. In order to accomplish this, they should be made from hard materials that can withstand high temperatures and intense pressure for extended periods. In order to meet this standard, heat-treating and rough machining are also required, along with possessing toughness, thermal wear resistance, and oxidation resistance properties.

Hydraulic forging presses use hydraulic systems to operate the press and create immense pressure to shape metals. A closed system prevents pressurized working fluid from escaping, keeping all pressing fluid under control.

Hydraulic forging presses are typically designed to meet diverse force, speed and precision requirements, making them adaptable to meet your unique needs and budget. To start off the process of selecting a hydraulic forging press with this capacity you should determine what force will be necessary for forging desired parts and choose an hydraulic press with this capacity.

Hydraulic forging presses use the unidirectional stroke of their ram to press sheet metal against an anvil, creating an enormous force against it and require much space and money for operations. They typically include motor-driven screw mechanisms to generate downward forces on the ram, hydraulic cylinders for holding dies, oil tanks to store hydraulic fluid, safety doors with limit switches and manual control valves as well as pressure gauges that monitor their operation.

Forged pieces have fewer metallurgical defects such as porosity, alloy segregation and voids, which reduce the need for machining while increasing strength. Furthermore, forging reduces scrap metal production thus saving energy while producing smoother surface textures which improve quality in finished products.
