Using special polyurethane material for isostatic pressing, it can be accurately formed, reduce subsequent processing, save powder, non-stick powder, easy to demould, good rebound, accurate size, easy to maintain shape, adjustable hardness, extended mold service life and other effects.
It used for some high-end applications, precision molding, isostatic pressing of new materials, precious metals and special-shaped parts.
From the perspective of physical properties, the strength of rubber materials and isostatic pressing polyurethane rubber sleeves are much different, including wear resistance, rebound, tearing productivity and other aspects. Therefore, the service life of bags made of polyurethane will be greatly improved. In the isostatic pressing of some large parts or powders with large shrinkage ratios, the characteristics of polyurethane isostatic pressing rubber sleeves will be more obvious.
Polyurethane material has better water resistance, oil resistance and antioxidant properties. This also enables the polyurethane isostatic mold to have a longer service life and can be stored for a long time.
If the rubber is stored for a long time, it may become brittle and the surface may become sticky. Clean and store the polyurethane isostatic mold after use.
It will not affect the performance if left for a long time.
