Analysis on Formation Causes for Defects of Powder Metallurgy Flyweights

摘要

The flyweight of powder metallurgy is a complex structure part of VE distribution pump. The components of the powder forming process often contain the defects such as instability of the quality, over tolerance of the size accuracy, and disqualification of the appearance. By analyzing the causes of defects and corresponding measures is taken. A once pressing compaction method is used to produce qualified products.
