Injection Valves Specification Example for Rental Motorcycles: Upgraded Version

This is a worked specification for injection valves 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 rental motorcycles 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 — Sintered Metal, 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

  • gravity casting
  • cold forging
  • CNC machining
  • electroplating
  • robot welding
  • rubber vulcanisation

Where this example applies

Programmes that run upgraded version most often specify this build for rental motorcycles. Related applications include municipal fleets, delivery vans, dealership service, emergency vehicles, export programmes.

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

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.

How long does sampling take?

Samples leave the factory in 14 working days, and each revision round adds about 5 days once you have seen the first piece.

What is the minimum order quantity?

The standard MOQ is 500 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.

Do you handle mixed containers?

Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 500 pieces per line.

Tell us the model, the fitment and the quantity and we will hold a production slot for you.
