Does an OEM Protective Case Supplier always need a site visit?

Answer: Yes. Licences travel by email; plates, engraving and a trial run need eyes.

Are 62 items too many?

Answer: The 18 key items are fixed, the rest trimmed by risk. Check all on a first order, changes later.

Can the three sample rounds be merged?

Answer: T2 and T3 can merge on small orders, never T1. Fit faults are cheapest on hand samples.

Where does tool ownership sit in the contract?

Answer: Its own clause: amount, owner, storage site, release terms.

Is 30 days enough for a change notice?

Answer: For most yes; tool modifications need 45 days to schedule a trial and a new first article.

OEM Protective Case Supplier Audit: Samples and Traceability

Quick answer: An OEM Protective Case Supplier is audited in five moves: licences and a visit list, capacity maths, sample approval, tool and jig ownership, then change control with lot traceability. Sixty-two items take two days, samples run three rounds, changes need 30 days notice.

FAQ

1. What to Audit in an OEM Protective Case Supplier

Most audits collapse into a tour: two lines, a folder of certificates, photos. Six months later the moulding sits with a neighbour workshop, the 1300-tonne press is really 800, the buyer's tool runs a rival's case.

An audit of an OEM Protective Case Supplier collects evidence, not impressions: licences, press plates, trial reports, lot ledgers. Eighteen of the 62 items are key.

Stage	Evidence	Time on site	If failed
Licences	Licence, QMS certificate, reports	Half day	Stop
Capacity	Press plates, tool ledger	Half day	Stop before quoting
Samples	Three rounds, measured reports	Half day	Conditional
Tooling	Engraving, storage agreement	Half day	Fix before signing
Change and trace	Change log, lot ledger	Half day	30 days to close

2. Licences and the Factory Visit List

For an OEM Protective Case Supplier three lines must agree: the licence scope lists plastic products and mould making, the address matches the plant, the QMS scope covers moulding and assembly. A sales-only scope or an old address must close before samples.

Reports need the right issuer: material data from the case maker, a CNAS or CMA mark, grade, tensile strength, Izod impact, ten RoHS substances. Finished reports carry drop, leak and latch fatigue within 12 months.

Soft items are usually missed: discharge permit, waste manifests, fire acceptance, power for 14 presses, customs registration. None sits on a certificate, yet each decides whether capacity runs.

3. Capacity and Equipment Maths

Capacity is calculated, not quoted: presses times 26 days, 22 hours, cavities and yield, divided by cycle time. One 800-tonne press at 210 seconds gives roughly 9,300 cases a month; a 30,000 order needs four such presses.

Look at tonnage spread, not headcount: fourteen presses from 550 to 1600 tonnes, four above 1000, hold a 700 mm case. Ancillaries count too: dryers, mould controllers at plus or minus 3 °C, robots, a drop tower, a leak bench.

Item	Benchmark	Evidence
Presses	14 units, 550 to 1600 t	Plates with model, year
Large presses	4 above 1000 t	Current schedule board
Mould heat	Plus or minus 3 °C	Setpoints on screen
Testing	Drop, leak, salt spray	Labels, 48-hour records

4. Sample Approval and a Light PPAP

In an OEM Protective Case Supplier audit samples run three rounds: five T1 hand parts for fit and foam, fifty T2 parts from the real tool, five hundred T3 parts for consistency. Keep one piece per round for 36 months.

A light PPAP works: level 3 means 18 documents, from design record and dimensional results to process study, control plan, measurement analysis and submission warrant. Key dimensions need Cpk of 1.33 or the tool goes back.

Allow 15 working days, five per round plus review.

5. Tooling, Jigs, Changes and Traceability

Tools in an OEM Protective Case Supplier plant need a ledger: buyer code and tool number engraved on the side, jigs numbered by operation, handed over in sets of 12. Acceptance takes three trials: fill, dimensions, 200 consecutive shots.

Change control covers man, machine, material and method: a new resin grade, another press, a cavity change or a process tweak need 30 days notice and a fresh first article.

Traceability rides on the lot number. Twelve digits combine date, press, shift and serial, tying shipping to feeding records for 36 months, so a claim finds its press in two hours.

Record	Content	Retention
Tool ledger	Number, cavities, trials	Whole life
Jig list	Operation, sets, handover	36 months
Change notice	4M type, date, first article	36 months
Lot trace	12-digit lot and feeding record	36 months

Conclusion

Auditing an OEM Protective Case Supplier turns five questions into records: may they mould, can the presses hold the size, do samples repeat, who owns the tool, can a lot be traced. Run them in order and the OEM Protective Case Supplier is chosen on evidence.
