Precision Cold Heading of a Steel Plunger Cap for the Automotive Industry

The product shown here, a steel plunger cap, which was designed for use within an internal combustion engine, in an automotive application. The parts where constructed of C1018 steel, manufacturing required precision cold heading which we performed on our four station nut former.

This project required both precision and high speed manufacturing in order to maintain the customer's specifications. The part measured .309" in length, with an outside diameter of .594", and an inside diameter of .135", and featured a natural finish. The customers design specifications required maintaining tolerances of ±.001", with true positioning of .005", and perpendicularity of .001". Quality was maintained with dimensional testing throughout the 6 million part manufacturing run that we perform annually.
