| 摘要 |
The invention refers to a method and an apparatus for producing multi-level components with conform target density from powdered material. The powdered material is filled into a mould die, which includes a multiple of lower and upper relatively movable punches, and the filling height of the column over each punch is associated to the geometrical levels of the final component. The material is optionally pre-compacted by individual static pressure acting on each punch and is compressed by at least one shock or impact device from at least one direction. Compensating adjustments for powder flow between columns and for density gradients are made during the pre-compression and shock compression.
