How to deal with pitting on aluminum alloy die castings?
2024 / 04 / 28
Low pressure casting can provide a lot of useful information for flow field analysis of casting molds. The casting case requires injection pressure and locking pressure. You should know that this part is complete. Model flow analysis ensures the diversity of filling problems. For example, shortwave, foam, imbalanced filling, etc. Mold flow analysis can change process conditions such as gate position and injection speed. In deformation analysis, it is sometimes necessary to predict deformation trends. Deformation analysis can be used to compare changes in gate position, wall thickness, and design. Check the prototype through flow analysis and solve key issues. The efficiency of the circulating water cooling channel can be determined through analysis. The use of cooling deformation analysis method has improved accuracy. Due to the difficulty in replacing cooling water in the mold. This analysis is very useful before mold opening. The welding position can be predicted through mold flow analysis. At the same time, it helps to prevent straight lines from appearing easily. Mold flow analysis can also provide clues that affect welding quality. For example, pre melting point and welding pressure. How to handle the pitting of stamped castings? Due to the low temperature of the mold or alloy liquid, small pitting corrosion may appear on the surface of the casting under approximate negative pressure, resulting in die casting defects. Analysis of the causes of pitting corrosion in castings During filling,

Sometimes, mold growth occurs on the surface of aluminum die casting. How can we resolve this situation? It is highly likely that scenario one: If a similar phenomenon occurs, there are two possible reasons:? 1. The results of air oxidation of cutting fluid;? 2. The residual water caused by the product starting to cool after removal. It is highly possible that situation two: mainly due to inadequate waterproofing, yellowing phenomenon: air oxidation of cutting fluid and concentration of release agent during aluminum die casting. It is very likely that scenario three: the problem of slag removal agent when solving aluminum alloy profiles in aqueous solution, the slag removal agent lacks the composition of fluoride salts, and check the secret recipe of the slag removal agent. The most common solution is to add 0.2-0.5 sodium fluoroaluminate throughout the slag discharge process of aluminum alloy profiles in aqueous solution, which can avoid the phenomenon of color fading and mold growth after casting production and processing. It is very likely that situation four: What is the problem with the spray painted architectural paint! Over time, the surface of the product may develop mold due to air oxidation. It is highly possible that situation five: Aluminum alloy profiles are bimetallic, and when they come into contact with acidic or weak alkaline components, they will become different colors. If the cutting fluid is selected incorrectly during the entire process of mechanical processing and manufac
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. Co
