Coining
Coining allows the creation of various shapes on a sheet of metal using a punch, die, and press that gradually deform the metal according to project specifications. This process is suitable for multiple applications, particularly in the bodywork, automotive, and agricultural sectors.

Coining process
The coining process involves using a punch and dies with the same angle of inclination, which helps eliminate springback (the tendency of the material to partially return to its original shape).
The shapes that can be obtained include:
Knurls: superficial incisions that improve grip, friction, or aesthetic appearance.
Housings: cavities designed to accommodate other components or parts.
Bevels: features that make sharp corners safer, enhance aesthetic appearance, and facilitate assembly.
Stamped letters or symbols: a process for permanently marking materials.
Thickness adjustments: increasing or decreasing thickness in specific areas.
Metals suitable for coining
Materials suitable for coining must be malleable. Common materials include stainless steel, aluminium, brass, iron, phosphor bronze, and titanium. Other materials, like cast iron, can be more challenging to coin.

Stainless steel
Stainless steel can be coined due to its moderate malleability and corrosion resistance.

Moulds design service for metal coining
MP uses customer-provided dies and offers, with partner companies, a custom mould design and development service suitable for metal coining. Mould design requires particular attention to the piece geometry, the type of material to be processed, and the pressure applied. The die must also ensure precision and repeatability of the forming process while minimising defects and potential surface errors. MP, supported by a strong network of partners, optimises the die geometry and characteristics to ensure efficient and high-quality production.
