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...

Shrinkage occurs when the temperature of molten metal decreases. When the temperature of molten metal decreases, the surface and internal temperatures do not decrease at the same time. The surface layer of molten metal cools very quickly, and then the internal temperature decreases. It can be seen from this that the liquid metal begins to condense from the surface, and the internal part slightly lags behind the condensation circle and contracts. If the metal liquid is not added to the inside of...

Theory of Spray Filling for Aluminum Alloy Die Casting The theory of spray filling in aluminum alloy die casting was proposed by Frommer in 1932 based on practical experience in zinc alloy die casting and through a large number of experiments. Frommel conducted an analysis based on the ideal liquid flow and believed that the filling process of liquid metal follows the laws of fluid mechanics, and there are friction and vortex phenomena. Through experiments, it is believed that when molten metal...

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...

Three stage filling morphology In the first stage, after the metal flow limited by the area of the inner gate is injected into the mold cavity, it first impinges on the opposite mold wall, extending in all directions along the mold surface. When the mold cavity has the correct thermal balance j, a surface layer is formed on the mold wall through which the metal flows, which is the outer shell (thin shell) of the die casting. This stage affects the surface quality of the die casting. In the...

The aluminum alloy die casting process is based on two methods: hot chamber die casting and cold chamber die casting. The main difference lies in the location of alloy melting depletion. During hot chamber die casting, the pressure chamber is usually immersed in the metal liquid of the cyanotic cochlea; while cold chamber die casting refers to the separation of the pressure chamber from the alloy melting process, and is divided into three forms, horizontal, vertical, and fully vertical,...

Basic Principles of Cold Chamber Aluminum Alloy Die Casting Process The pressure chamber of cold chamber die casting is separate from the holding furnace (alloy melting and exhaustion). During aluminum alloy die casting, first use a quantitative spoon to take out the metal liquid from the holding furnace and pour it into the pressure chamber, and then use the injection punch to perform die casting. According to the pressure direction of the injection punch, it can be divided into horizontal,...

Zinc alloy die casting is a processing form with high production efficiency and one-time molding. It can process structural parts with complex shapes and is widely used in automobiles and home bathrooms. However, zinc alloys are not resistant to atmospheric corrosion, and must be coated with copper or chromium protective decorative coatings on their surfaces. The substrate characteristics of the workpiece itself and its special processing form have a significant impact on electroplating.

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...
