The advantage of Powder granulation in PM


Powder flowability is improved and improvement. Powder granulation, the particle diameter than the original powder particle size is large, each around particles can be exposed to the reduction in the number of particles, so its adhesion, cohesion and friction force is decreased greatly, thus improving the mobility of particles.

The reduction of powder and diamond segregation and aggregation, more uniform distribution, improving the performance of products. Granulation process in advance, diamond powder mixed evenly with the adhesive, and then mixed with solvent wetting granulation, each diamond is quilt powder package, and then cold pressure forming and sintering, thus preventing the powder segregation and diamond aggregation, and then improve the products sintering properties, uniformity and stability of the product.
