Radiator End Cap Casting with Sealing and Fit Review
Radiator end caps are small parts, but the sealing face, hole position, wall thickness, and burr condition can decide whether the part assembles smoothly. Before quotation, the drawing should be reviewed as a functional cooling component, not only as a simple casting.
Radiator end cap, sealing face, mounting holes, wall thickness, machining allowance, material, and inspection points reviewed from the drawing.

Sealing Areas to Confirm
Sealing faces, gasket contact areas, bolt holes, cover edges, local wall thickness, and flatness notes should be checked before sampling.
Casting and Machining Review
We review material, casting route, machining allowance, datum faces, hole tolerance, deburring, surface finish, and dimensional inspection access.


What to Send for RFQ
Send the drawing, material grade, quantity, sealing notes, machined faces, hole tolerances, surface finish, and inspection requirements.
