Quick Detail

Description

Cold forging is an impact forming process that plastically deforms a piece of raw material, under high compressive force, between a punch and a die within suitable equipment such as a machine press.

Some basic techniques include extrusion (forward, backward, forward and backward), coining, upsetting, and swaging. These techniques may take place in the same punch stroke or in separate operations, depending on the specific application requirements.

In essence, cold forging is a displacement process that forms existing material into the desired shape; contrast this with conventional machining, in which material is removed to create the desired shape. As seen in the following sections, this distinction offers several significant advantages. The final section provides some of the key factors that should be kept in mind when considering cold forging as a manufacturing process.

There are generally 2 types of dies used in cold forging:

Open Forging: Material is allowed to escape after the cavity is filled.

Advantage: Lower stress and load
Disadvantage: Some post-machining may be required, depending on application requirements

Closed Forging: Die cavity volume is exactly the same as material volume in order to achieve outputs of net shape or near net shape.

Advantage: Eliminates need for post-machining
Disadvantage: Higher stress and load; die could be seriously damaged if the material is in excess

Higher Productivity for High Volumes

A primary reason for many companies moving to use cold forging is their need to achieve higher throughput from the production line. In many cases, conventional processes (such as machining, welding or other fabrication methods) involve multiple-pass operations to remove material and finish the part (e.g. vertical, horizontal, bulk removal, detail touch-up, etc.). In contrast, cold forging is typically a single-pass forming process that deforms the existing material into the desired shape.

Depending on part-specific parameters, the time savings per piece can deliver major productivity improvements. For example, some parts that take 3 to 5 minutes per piece to machine can achieve a throughput of over 50 parts per minute when cold forging is used instead.

The opportunity to achieve productivity improvements of over 100 to 200 times offers a fast return on investment in cold forging die and tooling. Thus, many companies have opted to use other methods only for prototyping or during the early production phases, with a transition to cold forging planned for the lead up to higher volume production ramp-up.

What are the advantages of cold forging?
The major advantages of cold forging are close dimensional tolerances, good surface finish quality, and the use of lower cost materials to obtain the required strength by work hardening without requiring heat treatment
