During the filling and pressing process, metal powder will overflow from the mold, resulting in the inability to fully utilize the material and wasting raw materials. The overflow of powder will cause the final formed parts to be insufficiently strong, reducing the filling and pressing effect. At the same time, foreign matter may remain when the mold is left stationary for a long time. Because the mold is heavy, the cleaning process is cumbersome and time-consuming, which indirectly reduces the efficiency of filling and pressing. Utility Model Content
