Polyurethane Isostatic Pressing Molds/Bags for Silicon Carbide Crucible
Silicon carbide crucible actually refers to a graphite-silicon carbide material crucible. Its main components are natural flake graphite and silicon carbide. Natural flake graphite and silicon carbide. Crucibles made of this material are used in most of the melting of non-ferrous metals such as copper alloys and aluminum alloys. Compared with graphite-clay material, silicon carbide crucible has the characteristics of other products such as excellent durability, high temperature resistance, high thermal conductivity, small thermal expansion coefficient, and resistance to rapid cooling and rapid heating. And its good performance has gradually caught up with the latecomers, and the demand in the market has accounted for about 97% of the total.
The silicon carbide crucible adopts the isostatic pressing method, also known as the hydrostatic pressing method, which is to put the powder to be formed (sometimes a certain proportion of the binder is pre-mixed uniformly) into the elastic material made of plastic or rubber. In the mold, put the mold into a high-pressure container filled with a rigid liquid medium, and then apply pressure to the liquid medium. Due to the incompressibility of the rigid liquid medium and the characteristics of uniform pressure transmission, the pressure passes through the liquid wrapped around the elastic mold. The medium is evenly transferred to the elastic model, and the blank material filled in it is pressurized, and finally a product of a certain shape is obtained. The characteristic of the isostatic pressing method is that the embryo body is evenly stressed around the body, so this molding method is especially suitable for preparing products with complex shapes that cannot be prepared by other molding methods. At the same time, during the isostatic pressing process, the forming pressure can be adjusted arbitrarily. Compared with other forming methods, the isostatic pressing forming blank has higher density and higher uniformity. During the firing process, the embryo body shrinks little and is not easily deformed.
Silicon carbide crucible refers to graphite-silicon carbide crucible, its main components are natural flake graphite and silicon carbide, silicon carbide has many advantages, using it as raw material not only ensures the working efficiency and effect of smelting, but also after our user experience It is also highly praised and has opened up a vast market for silicon carbide crucibles.
