What is electroforming?
Electroforming is the technology of replicating molds. The process consists of using an electrolytic bath to deposit ionized metal onto the surface of a mold.
Once the process is completed and the desired thickness is achieved, the electroformed part can then be separated from the mold.
Compared with other metal forming technologies, electroforming can replicate the surface of any mold with extreme accuracy.
For example, it is even possible to replicate holographic (1㎛ lattice shape) or human finger-print patterns.
OUDENSHA has been developing and introducing badges, metal stickers and high precision parts through the use of this electroforming technology over 60 years, making it a pioneer of this field.
