Document Type and Number:
WIPO Patent Application WO2003008131
Kind Code:
A3
Abstract:
A method for the high-velocity compaction of a part from particulate material is disclosed. The method includes the steps of providing a cavity that is at least partially formed by at least one bottom punch, inserting a pre-form that includes at least two levels into the cavity and moving an energy controlled main ram toward the pre-form at a high velocity to increase the density of the pre-form and form the part. A multiple-level part from particulate material and a high-velocity compaction press are also disclosed.
