Control & traceability
TPR design, production and bonding sit with one dedicated capability, so pad geometry and adhesion are controlled at the source rather than assembled from whatever a subcontractor happens to supply. Sewing and dipping run in controlled units against the approved revision, and more than one approved unit in the network keeps capacity resilient without an uncontrolled switch of manufacturing.
A shipped batch carries an identifier: product code, batch code, size and date code, on the label, polybag, inner box or master carton. Internally the chain runs from customer and PO through product code and revision, production batch, material lot, manufacturing unit and tooling to QA release and shipment. Production complete is not the same as released: a consignment is not released until QA, the required tests, quantity, packaging and documents are confirmed.
A test report is evidence for the configuration it was run on. It is tied to a product code, a revision and a covered configuration, and a change to material, structure or performance triggers an applicability review before that result is quoted again. Where no report exists for a configuration, the record says so, and the configuration states whether its evidence is Field Verified, Lab Verified or Not Verified.
