[0002] Powder metallurgy cam is a cam part made by powder metallurgy. Powder metallurgy is a process technology that produces metal powder or uses metal powder as raw material, and then forms and sinters it to manufacture metal materials, composite materials and various types of products. Cam refers to a mechanical rotating or sliding part that transmits motion to a roller moving close to its edge or a needle bar moving freely on the groove surface, or it receives force from such rollers and needle bars.
