Elector Forming Insert for Knob

1. Master Pattern Creation – A high-precision master model (typically made of aluminum or resin) is machined or 3D printed to the exact specifications of the desired insert.

2. Conductive Layer Deposition – The master is coated with a conductive layer (e.g., silver or graphite) to facilitate electroforming.

3. Nickel Electroforming – The master is submerged in an electrolytic nickel bath, where nickel ions are deposited onto the conductive surface, gradually building up the insert structure. This process ensures micron-level accuracy and excellent surface finish.

4. Separation & Finishing – Once the nickel layer reaches the required thickness (typically 2-5mm), the electroformed shell is separated from the master. The insert is then polished, trimmed, and heat-treated (if necessary) to enhance durability.

5. Quality Inspection – The final insert undergoes rigorous testing, including dimensional checks (CMM), surface roughness analysis, and trial molding to ensure performance.

Nickel electroforming insert are ideal for micro-featured plastic parts (e.g., medical devices, optical lenses, and automotive clips) due to their wear resistance, corrosion resistance, and fine detail replication.
