Automotive Door Panel Specification Example for Passenger Cars: Adjustable Type
Automotive Door Panel Specification Example for Passenger Cars: Adjustable Type
This is a worked specification for automotive door panel in a adjustable 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 adjustable type version exists because the duty cycle on passenger cars is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a fitment that looked right on paper and failed on the bench.

Example specification
| Item | Automotive Door Panel |
|---|---|
| Application | Passenger Cars |
| Version | Adjustable Type |
| Base material | Brass |
| Controlled dimensions | 6 key dimensions, recorded per lot |

| Finish | anodised |
| MOQ | 500 pieces per specification |
| Sampling | 7 working days, 5 days per revision |
| Compliance | TUV |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Brass, 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
- robot welding
- assembly line testing
- rubber vulcanisation
- CNC machining
- die casting
- precision stamping
Where this example applies
Programmes that run adjustable type most often specify this build for passenger cars. Related applications include city buses, aftermarket retail, rental motorcycles, delivery vans, workshop replacements.
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
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 500 pieces per line.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the TUV-compliant build instead of a fresh interpretation.
What testing is included?
Standard lots ship with dimensional and hardness reports. TUV documentation is issued with the shipment when your market requires it.
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.
