COMPACTION METHOD FOR HIGH DENSITY POWDER METAL PRODUCTS

摘要

The present invention relates to the filed of powder metallurgy and a compacting method for powder metal products comprising the following steps: a) filling a metal powder, optionally comprising an internal lubricant, in a die cavity; b) compacting the powder to a compact with an intermediate density; c) moving the compact a predetermined distance towards the exit of the die cavity; d) performing a second compaction to achieve a compact with a target density; e) ejecting the compact.
