What are the main factors that affect the die pressing process?
Publisher:Jingsimai     date:2018-10-09

1.effect of powder properties

The powder with high hardness, low plasticity and high friction has poor compactibility, which can be improved by adding lubricant or molding agent; the powder with low purity and high oxygen content has poor compactibility, which can be overcome by reducing the raw powder; the powder with single fine or coarse particles and regular shape has no compactibility. Ideally, the use of mixed particle powder and powder with complex particle shape can improve the pressing performance.


2. the impact of the suppression process.

The smoother the surface of the mold, the higher the hardness, the greater the rigidity, the more conducive to the increase and uniformity of the density of the bad body; the density of the green body by bi-directional pressing is higher and more uniform than that by unidirectional pressing; the lower the pressing speed and the longer the holding time, the more conducive to improving the density of the green body, especially for large size or complex shape abrasive tools. It's important.
