1. Requirement and risk review
Before a quotation is treated as final, we identify the operating conditions that affect product risk. These may include current load, voltage, temperature, vibration, moisture, UV exposure, salt exposure, mating compatibility and installation space. The review also records destination-market documents requested by the buyer.
2. Specification confirmation
The project specification should include the parameters that can be checked during sampling and production. Depending on the product, this can include material, conductor cross-section, insulation type, terminal material and plating, housing resin, dimensions, cable length, torque requirement, current rating, fuse format, labeling and packaging.
3. Sample and approval record
A sample is compared with the approved requirements before bulk production. Buyer approval should record any allowed deviations and identify the approved version. For mating components, fit and connection should be checked with the actual counterpart whenever possible.
4. Production checkpoints
The production partner and inspection scope vary by item. Typical checkpoints can include incoming material identification, first-piece confirmation, crimp appearance and pull-force testing for cable assemblies, dimensional checks for molded parts, plating or surface checks, label verification and packaging confirmation.
5. Pre-shipment inspection
Before shipment, the order can be checked against the approved specification and purchase order. The inspection plan may cover quantity, workmanship, critical dimensions, basic function, markings, accessories, packaging and carton information. Sampling level and test method should be agreed before production when the buyer has a defined standard.
6. Product document matching
Certificates and test reports are model-specific. A report should not be assumed to cover every visually similar product. When compliance documents are required, the exact model, rating, construction and applicant or manufacturer information should be compared with the ordered item before approval.
| Product group | Common checkpoints | Buyer input needed |
|---|---|---|
| Cable assemblies | Conductor size, length, crimp, terminal, polarity, continuity, label | Drawing, current, cable standard, connector orientation |
| Battery terminals | Material, plating, stud size, dimensions, clamp fit, workmanship | Battery post type, cable size, environment, target market |
| Connectors | Mating fit, keying, contact material, insertion, housing and sealing | Counterpart, current, voltage, cycles, IP requirement |
| Fuse holders | Fuse format, contact fit, conductor interface, housing and cover | System voltage, fuse type, current, mounting environment |
What buyers should put in the purchase order
- Approved drawing or specification revision.
- Approved sample reference and any agreed deviations.
- Critical-to-quality characteristics and acceptance limits.
- Required inspection records, photos or third-party inspection.
- Required product documents tied to the exact model.
- Packaging, label, barcode and carton-mark requirements.
