Radiator Cap for Great Wall Poer: Tempered Glass
This radiator cap for the Great Wall Poer is specified around tempered glass, which decides how it behaves in service far more than the part name does. We build to a written specification — base material, dimensions, finish and packing — and hold that specification on file so every reorder reproduces the approved piece.
The usual reason a programme changes supplier is not unit price. It is packing that arrived crushed at the port, or lead time that slipped twice before bulk started. Both are specification problems, and both are preventable.
