Car Door Assembly Specification Example for Delivery Vans: Folding Type
Car Door Assembly Specification Example for Delivery Vans: Folding Type
This is a worked specification for car door assembly 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 delivery vans is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually premature wear on the first batch.
Example specification
| Item | Car Door Assembly |
|---|---|
| Application | Delivery Vans |
| Version | Folding Type |
| Base material | Carbon Fibre Composite |
| Controlled dimensions | 3 key dimensions, recorded per lot |

| Finish | as machined |
| MOQ | 3,000 pieces per specification |
| Sampling | 10 working days, 5 days per revision |
| Compliance | ISO 9001 |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Carbon Fibre Composite, 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
- precision stamping
- powder coating
- assembly line testing
- laser cutting
- electroplating
- die casting
Where this example applies
Programmes that run folding type most often specify this build for delivery vans. Related applications include courier fleets, export programmes, off-road bikes, boat trailers, city buses.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 1.5 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
What testing is included?
Standard lots ship with dimensional and hardness reports. ISO 9001 documentation is issued with the shipment when your market requires it.
What is the minimum order quantity?
The standard MOQ is 3000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
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.
How is packing specified?
Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.
Send the specification you are working to and we will confirm what we can match, what we would change and why.
