What is Polyurethane Isostatic Mold?
A polyurethane isostatic mold is a specialized rubber mold made from high-strength polyurethane elastomer. It is designed for cold isostatic pressing, a process that applies high hydrostatic pressure to powdered materials inside a pressure vessel. The pressure, typically ranging from 100 MPa to 400 MPa, is transmitted evenly through the polyurethane mold to compress the powder into dense, uniform shapes.
Compared with traditional rubber molds, polyurethane CIP molds offer better elasticity, wear resistance, and longer service life under repeated high-pressure cycles. They are suitable for both wet-bag and dry-bag isostatic pressing systems.
What is the Advantages of Polyurethane CIP Molds?
Polyurethane isostatic molds provide multiple advantages in demanding forming environments
High Pressure Resistance
Polyurethane molds can endure high internal pressures without tearing or permanent deformation, making them reliable for repeated use in CIP machines.
Excellent Elastic Recovery
The mold returns to its original shape after pressing, ensuring consistent dimensions and product accuracy.
Durable and Wear-Resistant
Superior tear strength and abrasion resistance significantly increase mold life and reduce production costs.
Chemical and Oil Resistance
Polyurethane resists CIP media including water, oils, and solvents, maintaining its properties over time.
Customizable Design
Available in various sizes, hardness levels, and configurations to meet the needs of different applications and press machines.
