The paper describes existing methods of manufacturing automotive transmission elements (synchroniser cones) and suggest that the use of brass and ferrous PM materials is technologically limiting and can be very expensive. Techniques of using a multi-station transfer press to produce steel synchroniser cones have been developed for high volume production. A new means of producing synchroniser cones from strip steel using an orbital cold forging (OCF) press to achieve some of the complex geometry required is presented. Is was felt by Borg Warner that this relatively simple single station operation would complement its high volume transfer press, being particularly suitable for a lower volume or prototype production requirements. In 1994/95, a capital expenditure of more than Pound 1 million was made by Borg Warner Margam to develop a manufacturing cell for the production of synchroniser rings by an OCF route. This development work and the intention to establish further OCF based cells are discussed.
