Non-ferrous metal forging

We forge non-ferrous metals such as brass, copper and aluminium, increasing strength properties and saving raw material.

Forging of non-ferrous materials is a manufacturing process where compressive force is applied to the metal billet to form it into the specific shape of the die (mould). Generally this is a hot forging process where the metal bar is cut to length and heated to a specific temperature to suit the grade of material. More complex part shapes may require pre forming before the final forging takes place. Extra material is used in the forging process which is required to complete the component without any voids or surface flaws. Once forged, this extra material forms a thin ring of material around the part called a flashing. A second operation in a stamping press is then used to trim the flashing and the excess material sent for recycling.

The benefit of the forging process is that mechanical properties are improved over a cast or machined part due to the deformation and elongation of the material’s grain structure similar to that of the finished part.
The long term benefits of forgings with improved durability and less down time from mechanical failure can outweigh the initial cost savings of a machined or fabricated component.

Since the raw material is pressed into shape rather than machined away there are savings in manufacture time and raw material recycling.
Although initial forging setup costs can be relatively high due to the manufacture of the forging and trimming dies. Forging can often be more economical to produce especially in larger quantities than other processes.
