The advantages of the Polyurethane mold
In isostatic pressing, the prototype to be pressed is placed in a high-pressure container, the pressure is uniformly transmitted through the liquid pressure transmission medium, and the various parts are pressurized from all directions, so that the workpiece is formed and the desired effect is achieved. In this pressing process, the workpiece needs to be isolated from the pressure transmission medium, and cannot be in contact with the pressure transmission medium (hydraulic oil) to cause mutual contamination. This requires isostatic pressure molds (sleeves) that can meet hydraulic work.
Some advantages of the Polyurethane mold:
1. Polyurethane isostatic pressing mold has high resilience, fatigue resistance, low deformation rate, easy demoulding, and is used in dry bag and wet isostatic pressing for pressing ceramic product blanks, graphite products, cemented carbide and other non-standard powder molding .
2. High forming precision and smooth surface. The surface of the mold itself is very smooth and dense, the surface of the pressed product is smooth, the appearance is beautiful, the post-processing is less, and the cost is saved.
3. The mold itself is easy to form, and the cost of making special-shaped molds is low and the efficiency is high. Before the polymer material is made into a mold, the form is liquid, and it can be made into molds of various shapes. The cost of opening the mold is low and the production cycle is short.
4. The mold has good resilience, low deformation, aging resistance, long service life, and reduces production and use costs. The anti-oxidation and aging resistance of polymer materials are significantly stronger than those of traditional isostatic pressing rubber molds.
5. Oil resistance, chemical resistance, wide range of use, can be applied to a variety of working conditions.
Compared with steel molds and rubber molds, polymer isostatic pressing molds are easier to demould. The hardness of polymer materials can be adjusted. For some special-shaped molds, materials with lower hardness can be used, and demolding is very easy.
