Case Study: Custom Rubber Patch for a Car Interior Supplier in Vietnam

Rubber Patch for a Car Interior Supplier in Vietnam

A Car Interior Supplier approached us with a rubber patch requirement for the Vietnam market. The brief was specific: a defined look, a hard launch date and a unit cost that had to survive freight and duty. This case study records what was specified, what went wrong in sampling and how the bulk order was delivered.

The challenge

• Cartons packed to the factory ratio instead of the buyer's size ratio
• Shrinkage that only showed up after the first wash
• An interlining that bubbled after the first press

What we specified

How it was resolved

1. We rebuilt the specification around Recycled PET and locked the tolerance before bulk.
2. The finish was moved to Anodised Finish after strike-off tests showed better durability.
3. A pre-production sample was approved and retained as the golden reference.
4. Production ran with in-line inspection and a mid-run photo report.
5. Cartons were packed to the client's own barcode and ratio specification.

Result

• 50,000 pieces delivered inside the 8-week window.
• Unit cost held within 3.0% of the original quotation.
• Inspection-related rejection stayed under 1.5%.
• The specification is now 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.
