With the development of manufacturing technologies, to meet quality requirements of metal forming with variety of materials, servo stamping and forming machines have been widely used in production because they allow flexible control over stroke curve and forming speed to achieve optimized forging conditions. Diverse capabilities such as high-precision production, long mold life and high production efficiency are supported by using servo technology. In this paper, a method to product LED lamp cups through the use of servo forging technology is proposed. The servo metal forming machine used innovative motion control to extrude LED lamp cups. The negative pressure generated by the movement of punch tool will bring the lubricant to punch tool and billet. Therefore, the friction between the punch tool and the billet will be reduced and the surface roughness will be improved.
