Weight reduction of automotive components includes the coil springs used in car suspensions. Spring wire diameter can be reduced, but it is necessary to use high-strength spring material to maintain required mechanical properties. In Part 1 of this article, the authors look at the technology used in the mass production of suspension springs including the forming processes involved in the use of high-strength materials to lower the weight of these automotive components. In Part 2, the authors will explore numerical modelling of the coiling process relative to material properties and spring diameter size.

Abstract
Weight reduction of automotive components includes the coil springs used in car suspensions. Spring wire diameter can be reduced, but it is necessary to use high-strength spring material to maintain required mechanical properties. In Part 1 of this article, the authors look at the technology used in the mass production of suspension springs including the forming processes involved in the use of high-strength materials to lower the weight of these automotive components. In Part 2, the authors will explore numerical modelling of the coiling process relative to material properties and spring diameter size.
