Elevator controller enclosure manufacturing: route and DFM
How an elevator controller enclosure is bent, welded, masked and coated, with the door gaps, earth bonding and IP details that decide whether it passes.
Read
Degreasing galvanised steel parts before coating
Why oil, white rust and laser oxide ruin coating on galvanised steel, the pH window that protects the zinc layer, and the film build a Z275 sheet can take.
