Cold Isostatic Molding Mold
Isostatic pressing mold refers to the powder material used in the process of isostatic pressing molding. The powder material (or the blank body after prepressing) is used in the mold. It can be a hard metal mold, or an elastomer mold. Among them, isostatic elastomer molds are made of different materials such as rubber, silicone, polyurethane (PU), etc., and also include some simple molds. For example, plastic bags are used to press and form some small parts in the experiment. Characteristics of different materials of isostatic pressure mold.
1. The rubber mold is not very good in oil resistance and aging resistance. After a period of use, the mold will be corroded by oxidation, or after a period of time, the mold oxidation is serious and can not be continued to be used.
2. The silicone mold, the material is soft, the demoulding will be difficult after pressing, and the phenomenon of bonding between the mold and the forming blank body often occurs.
Isostatic pressure mould, special polyurethane material
According to the demand of isostatic pressure and specially customized polyurethane isostatic pressure mold, with the advantages of other materials, but overcome the shortcomings of other materials, is the ideal material for isostatic pressure mold, widely used in dry bag isostatic pressure equipment and wet isostatic pressure equipment, used in hard alloy, ceramics, graphite and other materials, excellent use effect. High rebound, fatigue resistance, low deformation rate, easy to release, used in dry bag type and wet isostatic press to press ceramic products, graphite products, hard alloy and other non-standard powder molding.
High forming precision, 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.
The mold itself is easy to form, and the cost is low and the efficiency is high when the special-shaped part is made. The polymer material is liquid before it is made into molds, which can be made into molds of various shapes, with low cost of mold opening and short production cycle. The mold has good resilience, low deformation, aging resistance, long service life and reduced production and use cost. The oxidation resistance and aging resistance of polymer materials are significantly stronger than the traditional isostatic pressure rubber mold, which does not deform in continuous use and will not get sticky like rubber. Oil resistance, chemical resistance, wide range of use, can be applied to a variety of conditions.
