Micromanufacturing In Nickel

Introduction to Electroforming

Find out why OEMs are turning to electroforming to fabricate ultra-precise metal parts!

Electroforming is an additive manufacturing process used in the creation of metal parts. What makes it different from plating is that rather than adding an additional layer to an existing part, electroforming allows us to create an entirely new piece particle by particle.

Electroforming is a process of electrodeposition in which a mandrel, or mold of a final part, is submerged in a metal salts solution (usually nickel sulphamate) and subjected to an electrical current. While the charge is being applied, the nickel particles adhere to the mandrel. Once the charge is switched off, we can take the mandrel out and separate the final parts from it.

Like etching, electroforming is widely used among OEMs with a need for miniscule yet precise component parts for their products. In industries ranging from microelectronics to medical and scientific instruments, electroformed pieces are playing a major role.
