Case Review
65Mn steel hardened adjusting shims, custom sizes and thicknesses. Processes include stamping, blanking, fine blanking, heat treatment, blackening, Zn-Fe plating, and nickel alloy plating. Through-hardened shims are heat treated in an isothermal furnace to boost hardness, tensile, and yield strength for a more durable component. Custom 65Mn flat adjusting shims are made from cold-rolled steel coils and high-carbon spring steel strip.

Manufacturing route
The published sequence for this part:
- Precision stamping
- Deburring
- Heat treatment
- Surface treatment
What decides the engineering
The route starts with precision stamping - a single-hit or short-tool run for a part where tolerance and flatness matter more than cycle time.
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.
