When Aluminum Alloy Die Casting products are processed later, there are many aspects that need to be paid attention to.
The first is machining. Since the die-casting products already have a certain shape, the machining allowance should be accurately planned during machining. Too much allowance will increase the processing cost and time, and too little allowance may not eliminate the surface defects generated during the die-casting process. At the same time, it is necessary to select appropriate tools and cutting parameters. Aluminum alloys are relatively soft but have high viscosity. The tools should be sharp and have good chip removal performance. The cutting speed and feed rate should be set reasonably to avoid problems such as built-up edge that affect the processing quality. For example, during milling, too fast a feed rate may cause an increase in surface roughness.
The second is surface treatment. If surface treatment such as electroplating and spraying is required, ensure the cleanliness of the product surface. There may be impurities such as mold release agent residues on the surface of die-casting products, which must be thoroughly cleaned and degreased, otherwise it will affect the adhesion of the plating or coating. When performing anodizing treatment, the oxidation process parameters, such as electrolyte composition, temperature, voltage and time, must be strictly controlled to obtain a uniform, beautiful and corrosion-resistant oxide film.
The next step is welding and assembly. For some die-casting products that require welding, the welding characteristics of aluminum alloys must be considered. Choose a suitable welding method, such as argon arc welding, and pay attention to the heat input control during welding to prevent product deformation or welding defects due to overheating. During the assembly process, accurate positioning and connection must be performed according to the design requirements of the product to ensure the matching accuracy between the various components. At the same time, it is necessary to check whether the dimensional accuracy of the die-casting product meets the assembly requirements, and if there is any deviation, it must be adjusted in time.
In addition, attention must be paid to the protection of the product during subsequent processing. To avoid damage to the product such as collision and scratching, appropriate packaging and handling methods can be used. In short, in the subsequent processing of Aluminum Alloy Die Casting products, from machining to surface treatment to welding and assembly, it is necessary to operate carefully and pay attention to every detail to improve the final quality and performance of the product.
