Crankshaft for Geely Coolray: Cast Iron
This crankshaft for the Geely Coolray is specified around cast iron, 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 documentation that arrived after the container shipped, or reorders that did not match the approved sample. Both are specification problems, and both are preventable.
