Manufacturing process of wheel key for vehicle wheel - involves extruding cylindrical hollow profile and then cutting off blank and shaping it to required shape

摘要

Firstly, a cylindrical hollow profile (8) is extruded. The second step then involves separating a blank (12) from the profile, the blank having a thickness approximately the same as the finished height of the key. The third step involves heat shaping the blank into the final shape. The heat shaping involves pressure forging. The material used for the key is an AlMg alloy. USE/ADVANTAGE - It is a simple and economical process.
