Brake Disc for An e-commerce seller in South Asia
An e-commerce seller came to us with a brake disc programme for South Asia. The brief was ordinary and unforgiving at the same time: a fixed launch window, a landed cost that had to survive freight and duty, and a part that had to match an existing sample. This case records what was specified, what went wrong in sampling and how the bulk order landed.
The starting point
- Premature wear on the first batch
- A supplier who changed material without saying so
- Packing that arrived crushed at the port
What was specified
| Part | Brake Disc |
|---|---|
| Client | An e-commerce seller |
| Market | South Asia |
| Volume | 5,000 pieces across 3 specifications |
| Base material | Titanium Alloy |
| Sampling rounds | 4 |
| Delivery window | 5 weeks from PO to ex-factory |
| Compliance | SAE J431 |
How it was resolved
- The specification was rebuilt around Titanium Alloy and the tolerance locked before bulk.
- A pre-production sample was approved and kept as the golden reference.
- Production ran with in-line inspection and a mid-run photo report.
- Cartons were packed to the client's own barcode and ratio specification.
- Documentation shipped with the goods instead of after them.
Result
- 5,000 pieces delivered inside the 5-week window.
- Unit cost held within 1.5% of the original quotation.
- Inspection-related rejection stayed under 1.0%.
- The specification is on file, so reorders reproduce the approved sample.
What we would repeat
Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.

Send the specification you are working to and we will confirm what we can match, what we would change and why.
