Polyurethane Elastomer Mold

Polyurethane Elastomer CIP Mold

Isostatic mould refers to the mould used by the powder material in the isostatic pressing process to hold the powder material (or the prepressed body), which can be a metal hard mould or an elastomer mould. Among them, the isostatic pressure elastomer mold is made of different materials such as rubber, silicone, polyurethane (PU), and also includes some simple molds, such as plastic bags pressed to form some small parts in the experiment. What are the characteristics of isostatic pressure molds of different materials?

1. Rubber mold, oil resistance and anti-aging is not very good, after a period of use, the mold will be oxidized corrosion, or after a period of time, the mold oxidation is more serious, can not continue to use.

2. Silica gel mold, the material is soft, it will be difficult to release after pressing, and the phenomenon of bonding between the mold and the forming body occurs from time to time.

According to the demand of isostatic pressure and special customized polyurethane isostatic pressure mold, both 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, for cemented carbide, ceramics, graphite and other materials, the use of excellent results. High rebound, fatigue resistance, low deformation rate, easy to release mold, used in dry bag and wet isostatic press pressing ceramic products blank, graphite products, carbide and other non-standard powder molding.

High molding 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 making the special-shaped mold. The polymer material is liquid before it is made into a mold, and can be made into molds of various shapes, with low mold opening cost and short production cycle. The mold has good resilience, low deformation, aging resistance, long service life and reduced production and use costs. The oxidation resistance and aging resistance of the polymer material are significantly stronger than that of the traditional isostatic pressure rubber mold, and the continuous use does not deform, and the aging will not be sticky like rubber. Oil resistance, chemical resistance, wide range of use, can be applied to a variety of conditions.
