MICRO ELECTRO FORMING

Micro electroforming is a high-precision manufacturing process used to create extremely fine and detailed metallic structures. It involves depositing metal ions from a solution onto a conductive mold (or mandrel) using an electrochemical process. The deposited metal layer replicates the mold’s surface features with exceptional accuracy. After the desired thickness is achieved, the mold can be removed, leaving behind the metal structure.

Micro electroforming is widely used in industries such as electronics, optics, and medical devices to produce components like micro-lenses, micro-gears, and precision molds. It enables the fabrication of parts with intricate designs, high aspect ratios, and tolerances within micrometer scales.
