Reasons for deformation in aluminum alloy die casting processing

2024-04-24

Reason for deformation of machine tool casting: to prevent sudden changes in thickness. Machine tool casting with small and uniform thickness should also be cooled, while machine tool casting with large and uneven thickness should be cooled in order from thin to thick, and the placement of the sprue should be reasonable. The slag hole is an irregular hole in the internal structure or external shape, and the casting of casting cannot be lowered during casting. Under the direct relationship of the workbench heat source, the parts of the CNC lathe and the bed casting will form different levels of deformation, causing the relative motion between the product workpiece and the CNC cutting tool to eventually break. Aluminum alloy die castings with sand cores are the next quarter of the CNC lathe. For dry CNC lathes, due to all production and manufacturing being adjusted by financial accounting instructions, the damage caused by thermal expansion is relatively serious. Before painting the CNC lathe, it is necessary to conduct a casting sound inspection on the plate bed, check the uneven appearance of the surface, and use object cutting to repair it. The dirt on the outside should be clean and tidy. Concrete pouring is continuous. The surface of machine tool casting should have weld nodules, and intelligent robot Aluminum Alloy Die Casting should completely or partially cover a layer of mixed chemical substances of metal composite materials (or nickel hydroxide) and sand (or industrial coatings) or a layer of calcined sand. Causing uneven and uneven surface of machine tool casting in China. Reduce the gaps in fine sand. Properly reduce the ambient temperature of the metal in situ concrete. The flame retardant grade of gradient sand and core sand. After the processing of precision casting, metal cleaning agents or industrial gasoline are used to remove or clean, ensuring the appearance of oil and other dirt. Continuous flowability during cast-in-place concrete.

Strictly control the effectiveness of molding sand and the molding process, and pay special attention to cleaning the mold cavity before closing the mold. aluminum casting manufacturers increase the temperature of molten iron. Reduce the viscosity of fly ash. Excellent slag blocking professional ability in concrete pouring management system. Improve the internal curvature of machine tool casting. Hot cracks on facility or bed casting have pear lines that penetrate or penetrate through (note if based on difficult shapes), metal composite materials at the opening, and oxidation of epidermal cells. The thickness of machine tool casting should adopt a compromise between uniform and developing trend sand and core as much as possible.
