Product introduction: The dry-type bushing - static mixing vacuum casting and impregnation system is specifically designed for the vacuum casting of high-voltage bushings and other products. It carries out centralized control over processes such as the loading of casting materials, deaeration, mixing, product vacuum drying, vacuum casting, pressure impregnation, and final solidification, to achieve automated production and increase production efficiency and product qualified rate.

Product introduction: The automatic static mixing vacuum casting equipment belongs to a more complete configuration of static mixing vacuum casting equipment. It can use semi-finished products (AB) materials such as resin plus silicon micro-powder and hardener plus silicon micro-powder, or raw materials such as resin, hardener, and filler. It is suitable for small batch production or large batch production.   Precise measurement and proportioning have a significant impact on the physical and electrical properties of the castings. Therefore, the accuracy of the ratio of resin to hardener directly affects the quality of the casting, and the proportioning is completed by the measuring pump. The plunger of the designed measuring pump is separately guaranteed by the executive motor for the suction and extrusion of the resin and hardener (which can contain fillers). Due to this structure working in a volumetric manner, the sealing and wear resistance of the measuring pump are crucial. The movement stroke of the measuring pump plunger determines the amount of push material.   When the wear resistance gap is small, it is easy to cause cylinder sticking, and due to the action of the filling material quartz powder, it will increase the wear of the plunger and cylinder liner. When the gap is large, it will cause material leakage, resulting in inaccurate measurement. The structure we designed uses special materials and process structures to ensure the wear resistance of the measuring pump. And the clearance of the measuring pump plunger and temperature, so that the surface of the plunger forms a mucus with a higher viscosity, thus allowing the resin or hardener to form a sealing ring between the plunger and the cylinder liner. This layer of high-viscosity sealing ring effectively prevents the leakage of the material, ensures the movement seal of the plunger, greatly improves the measurement accuracy, and solves the contradiction between wear resistance and measurement accuracy.   The static core technology is a two-component epoxy resin mixture. It is mixed evenly through the static mixer. In principle, the shorter the mixing time of the two-component mixture, the fresher the material obtained. Compared with the traditional dynamic mixing method, the mixed material is fresher and is suitable for the casting use of high-grade products.   The principle of static mixing and casting equipment is to push the material with equal pressure through the measuring pump to achieve "material segmentation - position movement - rejoining" turbulence. In addition to the above three situations, the fluid will also generate intense eddies in the cross-sectional direction, with strong shear force acting on the fluid, further dividing and mixing the fluid, and finally mixing to form the required emulsions. The reason why it is called "static" mixer is that there are no moving components in the static mixer. Through the cross-type, it realizes mixing more than hundreds of millions of times in an instant, which largely shortens the mixing time, and basically gives all the chemical reaction time of the two-component materials to the mold to be completed!

Product introduction: The static mixing vacuum casting equipment with filler drying is a professional equipment that integrates the functions of filler drying and static mixing, and carries out casting in a vacuum environment. It can realize the drying treatment of the filler to ensure the dryness and quality of the material, and at the same time, through the static mixing technology, make various raw materials be fully mixed evenly. Casting under vacuum conditions can effectively avoid the generation of bubbles and defects, and improve the quality and yield of the products.
