A stepped steel cover with a side hole – the step is a change in shell diameter mid-draw, formed by progressive dies. Steps add stiffness and create natural ledges for internal components to seat against, all without any welding or machining.
Function and Design
The stepped cover is small in the bill of materials and large in the warranty claim when it goes wrong. The stepped cover is checked against the drawing at each stage, not only at final inspection.
Key Features
- What makes a stepped cover hard is repeatability – the hundredth piece has to match the first one. Any drift in the stepped cover process is corrected at the machine, not sorted out at inspection.
- Paperwork matches the parts: material certs and dimensional reports on request.
- Volume pricing is supported by in-house tooling and long-run press and machining capacity.
- Material: We hold carbon steel (SPCC / DC01 or to print) for stepped cover production; special grades are sourced to the drawing when volumes justify.
- Process: the stepped cover is deep drawn, then deburred and finished on the second operation, stepped diameters held across operations, burr-free piercing on the second operation.
- Finish: The stepped cover is finished per print – passivation, plating and coating are all run in house or by audited partners.
- Size: Overall size to customer drawing.
- Custom: OEM/ODM to print: the stepped cover quotation includes material advice and tooling cost.
Where It Is Used
It earns its place in automotive sensor and motor housings, appliance and HVAC assemblies, lighting reflectors and covers.
Our Production Advantage
We draw in house on maintained presses and inspect first articles on the CMM. Tears, thinning and rim condition are checked at the press, not discovered at assembly.
