Car Cooling System Specification Example for Trailer Axles: Adjustable Type
Car Cooling System Specification Example for Trailer Axles: Adjustable Type
This is a worked specification for car cooling system 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 trailer axles is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually documentation that arrived after the container shipped.
Example specification
| Item | Car Cooling System |
|---|---|
| Application | Trailer Axles |
| Version | Adjustable Type |

| MOQ | 500 pieces per specification |
| Sampling | 7 working days, 5 days per revision |
| Compliance | RoHS |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Anodised Aluminium, 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
- surface grinding
- sintering
- assembly line testing
- injection moulding
- ultrasonic cleaning
- heat treatment
Where this example applies
Programmes that run adjustable type most often specify this build for trailer axles. Related applications include off-road bikes, three-wheelers, trailer axles, agricultural trailers, long-haul trucks.
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
How long does sampling take?
Samples leave the factory in 7 working days, and each revision round adds about 5 days once you have seen the first piece.
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. RoHS 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.
Tell us the model, the fitment and the quantity and we will hold a production slot for you.
