Die Cast Part is a kind of pressure casting part. It is a pressure-casting mechanical die-casting machine with a casting mold. The metal such as copper, zinc, aluminum or aluminum alloy heated to liquid is poured into the inlet of the die-casting machine. Die casting, casting copper, zinc, aluminum parts or aluminum alloy parts of the shape and size of the mold, such parts are often called die castings. Die-casting parts have different names in different places, such as die-cast parts, pressure castings, die-casting parts, die-casting aluminum, die-casting zinc parts, die-casting copper parts, zinc die-casting parts, Magnesium Die Casting Parts, aluminum die-casting parts, aluminum die-casting parts, aluminum Pressed alloy castings, aluminum alloy die-cast parts, etc.

Core Abstract: The content of aluminum in the earth's crust is second only to oxygen and silicon, ranking third, and it is a metal element rich in * content in the earth's crust.The development of three important industries of aviation, construction, and automobile requires that the material properties have the unique properties of aluminum and its alloys, which is greatly beneficial to the production and application of this new metal aluminum and is widely used.The rapid growth of China's economy has generated huge demand for aluminum, which has promoted the rapid development of the domestic aluminum industry.

Core Abstract: the aluminum alloy die-casting surface technology is rich and varied, and the aluminum alloy die-casting surface effect is very beautiful and fancy. let's look at the other two polishing processes of aluminum alloy die-casting parts.

Aluminum Alloy Die Cast Part Factory does not claim anodizing and plating of aluminum alloys. Precision Aluminum Die Casting parts are simple in appearances, such as angry lines, cold partitions, sand holes, and other shortcomings. Generally, the anode is changed to the material of aluminum extrusion type, and the plating is changed to zinc-aluminum alloy or zinc alloy. The so-called anodic oxidation of aluminum is an electrolytic oxidation process in which the appearance of aluminum and aluminum alloys is usually converted into an oxide film, which has maintenance, decoration and some other functional properties. The anodization of aluminum from this definition includes only the part of the process of forming an anodized film.

As a Metal Acceeeories Manufacturer, share with you the key points of die casting mold design, die casting mold production is not a problem. Die casting uses a cavity in a die-casting mold to apply high pressure to the molten metal. This process is similar to an injection molding process. Therefore, die-casting mold design is very important for the production of die-casting parts. If you want to manufacture high-life die-casting molds, you need to master the following design points of Die Casting Mould:

The anodized film of aluminum has high hardness, good corrosion resistance and abrasion resistance, and has good transparency so that the surface after the anodizing treatment maintains the original metal texture of the aluminum. However, Aluminum Alloy Die Cast Part participates in this very multi-metal material, which is prone to air defects, cold insulation, sand holes and other defects during the surface treatment of aluminum alloy die castings. Due to the second phase generated by the alloying elements and the electrode potential of the aluminum substrate Different, so the anodic oxidation behavior and mechanism of aluminum alloy is much more complicated than pure aluminum. At the same time, in addition to aluminum oxide and anions in solution, the composition of aluminum alloy anodic oxide film will inevitably have some alloying elements in aluminum alloy. A state, an oxide state, or an intermetallic compound state exists. Therefore, the appearance quality of the aluminum alloy die-casting oxidation treatment is poor, and the defect rate is high.

In the production process, in order to avoid the defects of Aluminum Alloy Die Casting, it is necessary to adopt effective measures to reduce the moisture of the raw materials as much as possible, strengthen the quality management of smelting, and improve the exhaust energy of the mold. The details are as follows:

Aluminum Alloy Die Cast Part surface treatment, the common causes of mold are as follows: 1. External environmental factors. Aluminum is a vivid metal, which is easily oxidized and turned black or moldy under certain temperature and humidity conditio

After the heat treatment of Die Casting Mould, corrosion and rust scars appear on the surface. The mold is prone to cracks after quenching and the mold is scrapped. The mold is rusted during use. The mold is left for a long time to cause rust.

The surface strengthening treatment can not only improve the wear resistance and other properties of the Die Casting Mould surface, but also can keep the substrate strong enough and toughness, while preventing the molten metal from sticking and etching, which improves the comprehensive performance of the die casting mold and saves alloy elements It is very effective to significantly reduce costs, make full use of the potential of materials, and make better use of new materials.

Today Die Casting Parts Supplier explains the important factors of zinc alloy die-casting plating technology: Since Zinc Alloy Die Cast Part has a series of excellent characteristics such as low density, high specific strength, and corrosion resistance, it will be more widely used in various occupations such as aviation, aerospace, passenger cars, and machinery. Praised by customers. Especially in the car industry, in order to reduce fuel consumption and improve power utilization, it is a long-term development trend to replace steel and aluminum castings with aluminum and nickel alloy castings. In the meantime, emphasis was placed on the pollution-free, high-efficiency, concise operation of refined technology, deterioration technology, grain refinement technology and rapid furnace detection technology.

In the usual casting process, there are occasional blackening of aluminum alloy die castings. Why is this? Today, Aluminum Alloy Die Cast Part Factory will come together to understand the cause of this phenomenon.
