All You Need To Know About Forging

Brockhouse has been forging for over 135 years and offers both upset forging and closed die hammer forging solutions from our workshop in the West Midlands.

Forging is the manufacturing process of hammering, pressing, or rolling metal into shape. This is either delivered from a forging hammer or press and is essentially the art of heating and working hot metal to a design or shape that is fit for a specific purpose.

It is important to note that the forging process is entirely different from the casting (or foundry) process, as metal used to make forged parts is not melted and poured (as in the casting process). The forging process can create parts that are stronger than those manufactured by any other metalworking process.

Forging can produce a part that is stronger than an equivalent machined or cast part, providing longevity and reliability in the most demanding environments.  There are many different forging types each with different benefits.

What is Closed Die Hammer Forging?

Closed die forging is a process in which the raw material is placed between two dies, which move towards each other to cover the piece fully or partially. The top die drops down onto the piece in the bottom die, compressing it and forging the shape.

With closed die forging, the internal grain structure of the metal increases the tightness and strength of the part.

What is Upset Forging?

Upset forging is the most commonly used forging process, when considering its high-volume production benefit. The process can be performed on vertical closed die and horizontal split die machines, and involves increasing the diameter of the piece, or deformation (often wire, rod or bar), by compressing its length under high pressure. 

The process also produces long parts with a forged end that are stronger and more resistant than cast parts. Typically known components from upset forging include bolts, screws, engine valves and other fastenings.
