Metal Stamping of a Steel Dimpled Annular for the Automotive Industry
As a full service supplier of precision metal stamping since 1959, at Manor, we have provided high quality, value added products and services to customers across a broad range of industries.
The project highlighted here is for an automotive industry customer, and was designed for use in an exhaust system. This ring shaped automotive component is also known as a 4” dimpled annular, and requires not only precision die stamping, but the durability to stand up to very harsh conditions.
Composed of standard cold rolled steel (ASTM A1008 CS Type B), manufacturing required the use of multiple precision dies due to the end user (our customer) not wanting to incur an initial high tool cost for a progressive die.
The raw material is initially formed with blanking dies, which is followed by embossing and extrusion dies. These latter two processes required execution by pressing the material in opposite directions, which was strategically accomplished by innovative tooling design.
The finished part features dimensions of 3.890” in diameter and 0.500” in height. With precision tooling, the required tolerances ±0.002” were easily achieved. The finished component was measured and inspected in accordance with the ISO 9001:2015 quality management program. This project resulted in production runs of 12,000 parts per year.
