Zinc alloy die-casting processing technology refers to a processing technology in which zinc alloy is melted and then injected into a die-casting mold for die-casting. Zinc alloy die-casting parts have excellent process performance and can manufacture parts with complex shapes, as well as high surface finish, uniform density and high dimensional accuracy. Therefore, they are widely used in automobiles, aerospace, electronic communications and other fields.
The processing technology of zinc alloy die castings generally includes the following steps:
The first step is to design the mold. According to the shape and size requirements of the product, a suitable die-casting mold is designed, including upper mold, lower mold and supporting cooling system, water spray system, etc.
The second step is to prepare the raw materials. Select a suitable zinc alloy material and heat it to the melting temperature, usually 420-460 degrees Celsius.
The third step is die casting. The molten zinc alloy is injected into the die-casting mold, and the metal liquid is filled into the mold cavity through high pressure. After cooling and solidifying, the formed zinc alloy die-casting part is taken out.
The fourth step is to remove the remaining material. The formed zinc alloy die-casting parts are subjected to processes such as residual material cutting and shot blasting to remove surface residual materials.
The fifth step is to treat the surface. Zinc alloy die-casting parts are surface treated through shot blasting, sandblasting, chemical treatment and other methods to improve their surface finish and corrosion resistance.
The sixth step is to perform heat treatment. For some special zinc alloy die-casting parts that need to be improved in strength and hardness, heat treatment is performed to improve their mechanical properties.
The seventh step is to perform processing. Carry out machining process for zinc alloy die-casting parts that require hole processing, thread processing, etc.
The eighth step is to carry out surface coating. Carry out surface treatment such as spraying and electroplating on zinc alloy die-casting parts that require anti-corrosion and anti-oxidation treatment.
The processing technology of zinc alloy die castings requires the help of advanced equipment and technology to ensure the quality and performance of the product. At the same time, strict production standards and process flows need to be followed, and the quality of each process must be strictly controlled to ensure the excellent performance and long service life of the final product.
Zinc alloy die-casting mold development is generally recognized and accepted by all due to its excellent quality, lightness and convenience, and is widely used in machinery manufacturing, aviation and other industries. Many aircraft fuselages are made of aluminum alloys to reduce their weight.
