Abstract
The influence of powder compaction pressure on the hydraulic cylinder block fabricated by powder metallurgy is investigated in this study. The cylinder block is compacted with powder under various compaction pressures and then sintered, and its density and dimensions are measured to reveal the relationship of the powder compaction pressure with the product quality. Moreover, finite element analyses of the density distributions are carried out under the same conditions with the experiments and the predicted results are compared with the measured ones.
