The pulleys are used to be produced by powder metal due to cost performance and high productivity. Recently, the timing belt pulleys for automotive engine are required extra high functions which have sensor or light weight, and the complex shape pulleys are tend to increase. This report introduces the examples of the design and engineering of these pulleys as follows.<BR>1)The light weight pulleys with thin wall curtain shape rim are lighter than stamping pulleys.<BR>2)The cam shaft pulleys with sensing cam are manufactured as utilizing powder flow during compacting.<BR>3)The crank shaft pulleys with sensing cam at flange portion for miss fire detection have high accuracy of angle phase between key way and sensing cam.
