Case Review
This magnetically conductive housing is drawn from DT4E pure iron for automotive solenoid valves. Pure iron is selected for the magnetic circuit; the part is deep drawn, flattened, trimmed and flanged, then zinc-nickel plated.

- Application: automotive solenoid valve housing (magnetic circuit)
- Process: pure iron coil → deep drawing → flattening → trimming → flanging
- Material: DT4E pure iron
- Surface: zinc-nickel plating
- Burr-free ends with chamfered, parallel faces
