Parts produced by aluminum die-casting process usually require some simple deburring and cleaning. Although aluminum die-casting can produce parts with complex and precise shapes, during the casting process, due to the molten aluminum alloy filling the mold and rapid cooling, some burrs or overflow may occur at the joints, hole edges, or mold parting lines of the parts. These burrs are formed by the overflow of excess metal parts when the mold is closed, usually appearing at the edges or connecting parts of the parts.
Burrs not only affect the appearance of parts, but may also affect the assembly accuracy and functionality of parts, especially in applications that require high precision and smooth surfaces. Therefore, in order to ensure the final quality and performance of aluminum die castings, it is usually necessary to remove these excess metals through deburring and cleaning. Deburring can be performed using manual tools, mechanical deburring equipment, or automated deburring machines, depending on the shape of the part, the size of the burrs, and production requirements.
In addition, parts produced by aluminum die-casting process may also require cleaning of casting residues on the surface, such as mold coatings, metal splashes, or other impurities generated during the casting process. The cleaning process usually includes sandblasting, brushing, or using chemical solvents to remove surface impurities to ensure that the surface of the part is clean and smooth, and to lay a foundation for subsequent treatments such as coating, anodizing, etc.
