Intake Manifold Specification Example for Emergency Vehicles: Upgraded Version

This is a worked specification for intake manifold in a upgraded version 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 upgraded version 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 premature wear on the first batch.

How the example is built up

  1. Start from the duty cycle, not from the catalogue photograph.
  2. Fix the base material in writing — Carbon Steel, in this example.
  3. List the dimensions that are actually controlled and the tolerance on each.
  4. Name the finish and what it has to survive.
  5. State the inspection level and who pays when a lot fails.

Processes involved

  • shot blasting
  • robot welding
  • die casting

Where this example applies

Programmes that run upgraded version most often specify this build for emergency vehicles. Related applications include light trucks, off-road bikes, three-wheelers, camper conversions, trailer axles.

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 1000 pieces per line.

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 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.
