- How does it make?
1. Mandrel Design
Pattern is formed on the substrate using photoresist, plating, or etching techniques.
2. Electroforming
The patterned substrate is placed in an electrolytic bath, where metal ions—such as nickel (Ni), nickel-cobalt (Ni-Co), or nickel-iron (Ni-Fe)—are precisely deposited onto the surface.
3. Separation
Once the metal layer reaches the desired thickness, it is separated from the mandrel, resulting in a freestanding metal component.
4. Finishing
Processes such as polishing, cleaning, dimensional trimming, and inspection are carried out to ensure product quality.
