AbstractThe achievement of high density at reasonable cost is without a doubt one of the major ques of the P/M industry. Hish density can be achieved through various processing mutes involving the shaping of the part and/or the sintering. In particular, single pressing methods such as warm compaction and die wall lubrication are known to give green density in the range of 7.2 to 7.5 g·cm-3 depening on the powder formulation. Nevertheless, these pressing techniques normally require tighter control, are costly and may reduce productivity compared to conventional pressing method. More recently, new high performance lubricants were developed to achieve higher green density than conventional lubricant by cold compaction or temperature-controlled die compaction. This paper presents the green and sintered characteristics of these newly developed high performance lubricants in a laboratory and production scale. In particular, the compaction and ejection characteristics of these new lubricants ale compared to that obtained with other conventional lubricants.
