What's the Polyurethane Isostatic Pressing Mold uses?
Polyurethane material used in isostatic pressing is oil-resistant, water-resistant, highly resilient, and has high tear strength, resulting in a long service life. Polyurethane exhibits good performance and does not affect performance even after prolonged storage (though its color may change). In contrast, rubber molds will oxidize and become sticky on the surface after a period of time, and oil and water can have certain corrosive effects on rubber.

The characteristics of the powder affect the filling density. The characteristics of the powder refer to the impact of the shape, particle size distribution, and surface condition of the powder on the filling density. The filling density of regularly shaped spherical particle powder is higher than that of irregularly shaped dendritic particle powder. The filling density of graded powders is higher than that of single particle size powders.
The Impact of Powder Filling Methods: In practice, natural filling, manual tamping, manual tamping, mechanical vibration, and centrifugal filling are commonly used. Among these, natural filling density is the lowest, while mechanical vibration filling density is the highest. Although manual tamping can achieve high filling density, it is often uneven, and the surface flatness of the pressed body is poor.
Impact of the Mold Itself: During the filling process, there is internal friction between the powder particles and external friction between the powder and the mold, limiting the powder's flowability within the mold cavity. Therefore, the mold's filling port should be at the highest point of the mold cavity. To reduce friction between the powder and the mold wall during filling, the mold wall surface should be as smooth and straight as possible. For flexible sleeves, a support device should be set outside the sleeve, which is beneficial for improving the powder's filling density.
