Alternator Cover for QJMotor SRK 400: OEM Replacement
This alternator cover is built for the QJMotor SRK 400 and supplied to a written specification, so the part that comes off the line in the next order matches the one you approved. Fitment, base material and finish are fixed before sampling starts — that is what keeps the oem replacement programme stable once it moves from first order to repeat order.
Most buyers come to us after something went wrong: reorders that did not match the approved sample, or a specification nobody had written down. Both are avoidable when the specification is written down before bulk and the approved sample is kept as the reference.

- Hardness and heat treatment — recorded per lot, not per batch of paperwork.

Ordering

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 is packing specified?
Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.
What testing is included?
Standard lots ship with dimensional and hardness reports. SGS documentation is issued with the shipment when your market requires it.
How long does sampling take?
Samples leave the factory in 7 working days, and each revision round adds about 3 days once you have seen the first piece.
