What Is Press Forging?

Press forging is the process of gradually changing a steel billet’s shape by compressing the steel between two large dies that are either hydraulically or mechanically manipulated. However, it’s not just about applying pressure. 

During this process, the steel is heated to a temperature that surpasses its recrystallization temperature (400 degrees Celsius to 700 degrees Celsius, or 752 degrees Fahrenheit to 1,292 degrees Fahrenheit). Once that happens, the crystal lattice structure of the steel is broken down, making the steel more ductile.

In this process, the steel becomes “softer,” or more malleable, so that its shape can be changed more easily by the pressure being applied by the two dies. 

Our team at Trenton Forging controls both the temperature of the steel during the forging process and the cooling rate to meet a customer’s specific tensile strength and hardness requirements.

What Presses Are Used In This Method?

At Trenton Forging, we use mechanical presses. 

Mechanical presses tend to be faster than hydraulic presses or screw presses. Driven by an electric motor, the mechanical press converts the rotational power of a flywheel into compressive force by way of either a knuckle joint, eccentric, or other mechanism to apply pressure onto the steel billet.

Benefits of Press Forging

The immediate benefit of press forging is that it produces a component with fantastic mechanical properties, such as better fatigue resistance and improved tensile strength. Additionally, press forging requires less draft than hammers, typically produces less scrap, and can be more economical for high-volume jobs.
