Case Review
This electromagnetic coil housing is used in the ESC electromagnet — the solenoid valve in the car's brake system — for Bethel Company. Process flow: incoming DC04 coil stock, stamping and deep drawing, hydrogen removal heat treatment, then barrel Zn/Fe plating. The inner and outer diameters plus the overall height are checked with a Go/no-go gauge, and the surface is inspected for scratches, dents or raised burrs.

Manufacturing route
The published sequence for this part:
- Progressive die stamping
- Heat treatment
- Surface treatment
What decides the engineering
The route starts with progressive die stamping, which suits a part formed in the strip: coil feeding, piercing, forming and cut-off inside one tool. Strip layout and die stations are the engineering content of the job, and the annual volume decides whether a progressive tool is the right answer.
Two things are settled before tooling: which dimensions actually matter to the assembly - a sealing face, a bearing seat, a coaxial diameter - and what tolerance the process can hold at those features. Everything else follows the general tolerance, which keeps tooling effort where it buys function.
Surface treatment sits at the end of the route. Cleaning and deburring are done in house; plating, phosphating, passivation, electropolishing and coating are placed with qualified external processors and recorded on the inspection plan, and batch heat treatment is handled the same way when the drawing calls for it.
Documentation and first article
A part like this is released with a first article inspection report against the confirmed drawing and a PPAP-aligned package at the level the customer's quality department asks for. Material certificates are kept per heat and IMDS entries are filed on request. The quality system is ISO 9001:2015 with process controls aligned to IATF 16949 requirements.
