Like steel forgings and aluminum forgings, copper forgings in CT Forge are operated under hot forging condition as well. Below are the main steps of hot forging process of cooper alloys in our company:

Rod Cutting
Before forging, we will first order cooper bars with the right specification (such as Φ30mm) from the material factory. When they are in stock, to insure filling the die cavity during forging, billets will be cut to a certain length according to the dimensions of final cooper forgings.

Heating
Since the billet will be forged under hot condition, the billets are then heated to a certain forging temperature. To insure a quality part, the forger must carefully control the billet temperature, as too cold the billet will not fill the die cavity completely whereas too hot it will result in a porous surface.

Forging
The dies are heated to insure proper metal flow, and the heated billet is placed in the lower half of the die cavity. With a downward stroke of the forging ram, the upper die is forced against the billet to form the desired shape. Since copper and copper alloys are readily forged, most commercial forgings are produced with a single closing of the press, no re-strike or reheating being required. This permits the use of single cavity dies rather than the more expensive progressive dies required by hard-to-forge materials, and reduces labor costs, die costs, and heating costs.

Forging rates vary between 100 and 1,200 pieces per hour with the majority of forgings being forged at 200 to 600 piece rates. Where quantities are large and the design is simple, considerable savings result from the use of multiple cavity dies, with more than one part being produced at a time.

It is during this process that the dense grain structure of the hot wrought extruded brass rod is further hot worked to assure a dense uniform product with excellent physical and mechanical properties. These superior properties frequently permit the use of forged parts which are lighter than those produced by other processes.
