Convertible Child Seat Specification Example for Workshop Replacements: Folding Type
Convertible Child Seat Specification Example for Workshop Replacements: Folding Type
This is a worked specification for convertible child seat in a folding type programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.
The folding type version exists because the duty cycle on workshop replacements is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually inconsistent hardness between lots.

Example specification
| Item | Convertible Child Seat |
|---|---|
| Application | Workshop Replacements |
| Version | Folding Type |
| Base material | Stainless Steel |
| Controlled dimensions | 4 key dimensions, recorded per lot |
| Tolerance band | ±0.1 mm |
| Finish | as machined |
| MOQ | 500 pieces per specification |
| Sampling | 7 working days, 3 days per revision |
| Compliance | CCC |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Stainless Steel, in this example.
- List the dimensions that are actually controlled and the tolerance on each.
- Name the finish and what it has to survive.
- State the inspection level and who pays when a lot fails.

Processes involved
- assembly line testing
- rubber vulcanisation
- precision stamping
- robot welding
- ultrasonic cleaning
- cold forging
Where this example applies
Programmes that run folding type most often specify this build for workshop replacements. Related applications include rental motorcycles, assembly programmes, boat trailers, utility trailers, off-road bikes.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 4.0 sampling on the finished lot.
- Finish inspection under agreed lighting.
- Carton drop test on the first lot of a new packing specification.
Questions buyers ask
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 500 pieces per line.
What testing is included?
Standard lots ship with dimensional and hardness reports. CCC documentation is issued with the shipment when your market requires it.
What happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
Can you match an existing sample?
Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.
Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
