Warm compaction of metal powder

Warm compaction gives a major advantage compared to the conventional "cold" compaction by producing changes in the pore morphology of sintered parts.
The result is that higher density levels are achieved and, at the same time, warm compaction products have more even density distributions, i.e. less variation in density within a component.
 
The warm compaction process is applicable to most powder/material systems. This will lead to higher strength and better dimensional tolerances. A possibility of green machining is also obtained by this process partly due to high green strength.
