This part is one kind of auto parts,we call it flat cap,and the process is gravity casting and machining.
the surface treatment is electrophoretic paint,and generally the color is black,of cource,
the color could be others if you need.
We sale standard parts, but not only, usually, we will receive a drawing from the customer first, if everthing goes well, we will open the tooling(mould), then do a few samples before producing batch orders,and we also could produce pure machining parts.

We would quote reasonably once received your drawing and requirement.

We always cherish the honest operating, double-wins and our respectable customers.
