Basic principle:

The powder processing technology, which utilizes high pressure to apply uniform pressure in all directions to the powder sealed in a flexible mold at room temperature, results in a compacted powder with high and uniform density as its core advantage.

Key steps:

1. Loading and sealing: The powder is loaded into a flexible mold and vacuum sealed to prevent infiltration and contamination.

2. Pressurization and pressure maintenance: Place the sealed mold into a pressure vessel, fill it with pressure, and maintain the pressure to fully densify the powder.

3. Pressure relief and demolding: Slowly relieve the pressure, remove the mold, and peel off to obtain the greenware.

Core advantages:

Extremely high and uniform density: The density variation can be controlled to be ≤1.5%, which is significantly better than that of unidirectional pressing (5%–10%), greatly reducing the risk of sintering cracking.

High green strength: easy to handle, store, and machine (turning/grinding/drilling).

No mold wall friction: no lubricant required, high purity, stable performance.

Wide range of applications: Capable of molding large-sized and structurally complex components.
