Under the normal die-casting conditions, the jet and jet flow die-casting machine presses the metal into the ordinary die-casting model cavity. At the initial stage, the metal liquid passing through the inner gate is directly shot forward at a high speed like a bullet under the action of motion energy, and its direction depends on the direction of the inner gate, The metal flow in this state is called "the metal liquid sprayed at high speed will collide with the cavity wall and core or other...

Theory of Full Wall Thickness Filling in Aluminum Alloy Die Casting The theory of full wall thickness filling in aluminum alloy die casting was developed by Brandt in 1937 using aluminum alloy to press into an experimental die casting mold. The test mold has internal gates with different thicknesses (0.5~2mm) and rectangular cross-section cavities with different thicknesses. The ratio of the cross-sectional area of the internal gate to the cross-sectional area of the cavity is 0.1~0.6. Brandt...

1) During die casting, minimize segregation. If aluminum segregation occurs in certain parts, during degreasing, aluminum will first dissolve, creating pores and pinholes on the surface of the die casting that cannot be cleaned, resulting in poor adhesion, and causing peeling and blistering of the coating. 2) The residue from the process of die casting and machining should be cleaned as much as possible after processing. Because the residue is an active metal, it will react with the solution in...

1、 Precision Die Casting Technology: The connecting parts of the aluminum alloy vehicle body frame structure are mostly formed by casting, and the casting methods used are mainly advanced high-precision die casting methods such as semi solid die casting. There are currently two forming processes for semi solid die casting: rheological forming and thixotropic forming. The former involves feeding liquid metal into a specially designed injection molding cylinder, applying shear by a screw device...

Correct use and protection of precision die casting molds: minimize rapid cooling and heating of the mold, maximize continuous production, and prohibit high-speed injection under cold mold conditions. During the process of precision die casting, the die casting mold has been changing back and forth between 160 degrees and 350 degrees. The hot expansion and cold contraction of the return mold rapidly cools and heats up, resulting in mold fatigue damage. Therefore, during the production of...

Try to reduce the injection speed and specific pressure to reduce the impact of the mold. During the production of precision die casting, the concavity and convexity of injection speed not only affect the filling speed and injection inner gate speed of precision die casting, but also increase the impact peak value when the injection speed is high. As a result, the erosion of the mold will increase, the impact peak value will increase, the impact force received by the mold will also increase,...

Let's take a look at how new energy vehicles dissipate heat, because the power battery produces a large amount of heat and the battery pack is located in a relatively closed environment, which can cause the temperature of the battery to rise. The battery module cooling system is a device used to dissipate heat in new energy vehicles. By cooling or heating the power battery, it maintains a better working temperature of the power battery to improve its operating efficiency and extend its life.
