Sprue picker is a uniquely designed product, which picks the sprue and drops them in a respective place. The servo motor actuates the sprue picker to work correctly. The angle to which the arm has to rotate is all predefined in a controller, and hence, the robot works accordingly. While using fully automatic systems, the sprue picker plays an important role.

When the mold part is ready, then the clamp opens. Hence the user takes out the mold part from the machine, and the next cycle of the injection machine starts. To avoid this labor action, the injection machine uses the sprue picker robot. The precise angular rotation achieves with a servo motor. The swinging angle of the swing arm robot varies with two different models of the robot (30°-90°) and (60°-90°).

The sprue picker robot retracts the sprue from the part. The picker then drops the sprue in a particular place wherever required, either the operator or the other side. Then it starts the next cycling process. Therefore, the operation of the entire picker works with the help of controller programming.
