Forging Parts

Forging relies on the use of dies to compress and shape metal, so it’s critical to determine what set of tools will be most effective to achieve the desired shape. In many cases, custom die design will be necessary to ensure that the final product aligns exactly to expectations. For larger production runs, this step might include the design and production of multiple dies designed for flattening, forming, or cutting.

Once planning and toolmaking have been completed, the actual metalworking can begin. First, the billet, or workpiece needs to be cut to size. Once cut, it must then be heated to the proper temperature. Once heated, the billet is ready to be formed.

At this point, the various forging methods begin to diverge. Depending on the process chosen, the billet may be heated and pressed between two dies or inserted into a molded cavity and compressed. In some cases, the operator will leave the billet at room temperature and work it manually with hammers in a process called cold forging.

Finally, there may be some necessary finishing procedures. For instance, some dies will produce flashing that must be trimmed.
