Performance Flywheel Specification Example for Emergency Vehicles: Folding Type
Performance Flywheel Specification Example for Emergency Vehicles: Folding Type
This is a worked specification for performance flywheel 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 emergency vehicles 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 | Performance Flywheel |
|---|---|
| Application | Emergency Vehicles |
| Version | Folding Type |
| Base material | Tempered Glass |
| Controlled dimensions | 4 key dimensions, recorded per lot |
| Tolerance band | ±0.5 mm |
| Finish | powder coated |
| MOQ | 1,000 pieces per specification |
| Sampling | 10 working days, 3 days per revision |
| Compliance | E-mark |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Tempered Glass, 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
- die casting
- cold forging
- ultrasonic cleaning
- powder coating
- gravity casting
- assembly line testing
Where this example applies
Programmes that run folding type most often specify this build for emergency vehicles. Related applications include fleet maintenance, municipal fleets, passenger cars, agricultural trailers, utility trailers.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 2.5 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. E-mark documentation is issued with the shipment when your market requires it.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the E-mark-compliant build instead of a fresh interpretation.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 1000 pieces per line.
How long does sampling take?
Samples leave the factory in 10 working days, and each revision round adds about 3 days once you have seen the first piece.
Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
