The brass hot forging process or hot stamping involves deforming a brass rod previously exposed to temperature and then forming it under the pressure of two dies.
The two metallurgical parameters to be considered during hot stamping are brass composition and temperature. Taking into account the composition of brass, the material has certain properties, and its mechanical properties, plasticity, fusibility and structural capacity are affected by any of the following technologies: Casting; Hot forging or stamping; Processing, Including bar turning.
Here are the advantages of hot forging.
There are many shapes of parts, this technology allows more choices in shape modification;
The strength required for deformation is small;
It can obtain excellent mechanical properties with fatigue resistance; this is due to its isotropic properties of strength: brass manufactured by forging maintains the same physical properties in all directions, and it is due to its internal structure and extrusion process ensure the obtained brass rod remaining basically unchanged.
Since there are no pores or cracks, the workpiece can be sealed perfectly;
Facilitate the subsequent processing of parts, thus becoming a more competitive and more complex element;
Brass hot forging process is cheaper than casting;
Possibility of recycling brass scrap.
