Case Study: Control Arm Supply for a police fleet in Southeast Asia

Control Arm for A police fleet in Southeast Asia

A police fleet came to us with a control arm programme for Southeast 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
  • Lead time that slipped twice before bulk started
  • Reorders that did not match the approved sample

Volume2,000 pieces across 6 specifications
Base materialKevlar Composite

Delivery window5 weeks from PO to ex-factory
ComplianceRoHS

How it was resolved

  1. The specification was rebuilt around Kevlar Composite and the tolerance locked before bulk.
  2. A pre-production sample was approved and kept as the golden reference.
  3. Production ran with in-line inspection and a mid-run photo report.
  4. Cartons were packed to the client's own barcode and ratio specification.
  5. Documentation shipped with the goods instead of after them.

Control Arm production run

Result

  • 2,000 pieces delivered inside the 5-week window.
  • Unit cost held within 1.5% of the original quotation.
  • Inspection-related rejection stayed under 1.5%.
  • The specification is on file, so reorders reproduce the approved sample.

What we would repeat

Fix the specification count early. Adding variants after production starts is the most expensive change a client can request.

Planning something similar?

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