Polyurethane CIP Molds

Polyurethane CIP Molds

Cold isostatic pressing is divided into dry bag mold pressing and wet bag mold pressing according to different powder loading methods. We have also developed targeted wet isostatic pressing molds, dry bag isostatic pressing molds, and dry bag isostatic press sealing sleeves. The fundamental difference between the two is: the isostatic mold pressed by the dry bag mold is not immersed in the liquid medium. After the pressing is completed, the press block and the mold bag are taken out, while the pressurized bag remains in the container for the next filling; The molded bags pressed by the bag mold have a long service life and high production efficiency, and are suitable for single-piece continuous production. Wet bag mold pressing is a commonly used pressing process. After loading, the mold bag is placed in a container and immersed in the liquid medium. After pressing, the mold bag and blank are taken out at the same time.

As an advanced forming technology, isostatic pressing technology has obvious advantages compared with traditional forming technology, mainly focusing on:

First: Products formed by isostatic pressing have high density and uniform distribution, there are no bubbles inside the product, and the microporosity between the finished grains is very low. Its mechanical properties and electrical properties are better than other forming methods.

Second: Isostatically pressed products have almost no internal stress, and the compacts can be directly fed into the kiln for sintering without warping or cracking.

Third: It is easy to produce products with a large aspect ratio (the ratio of length to diameter), while other methods are less effective or impossible to achieve.

Fourth: Make large-scale products and products with complex shapes made of high-melting-point, high-hardness materials.

Fifth: The green body formed by isostatic pressing has a lower firing temperature than other forming methods and does not pollute the high-purity compact material.
