What is the pinhole problem of aluminum alloy die casting in Huizhou?
Now there are many aluminum alloy die casting parts on the market, along with the die casting manufacturers. At present, aluminum alloy die casting has been able to meet the needs of many consumers, although it has solved the problem of people's needs, but with the quality of die casting parts. Pinholes on the surface of aluminum alloy die casting not only affect the appearance of die casting, but also affect the quality of die casting.

Although it solves the problem of people's needs, there is also the quality problem of die castings. The appearance of pinholes on the surface of aluminum alloy die castings not only affects the beauty of die castings, but also affects the quality of die castings. Do you know what types of aluminum alloy die casting pinholes are? Shuangcheng Hardware will give you a detailed explanation aboutPinholes in aluminum alloy die-castingparts.
I. Mesh pinholes in aluminum alloy die-casting: pinholes will be dense and form a mesh in the macrostructure, and there will also be a few large holes. It is not convenient to check the number of pinholes per unit area, and it is also difficult to measure the diameter of pinholes, so it is necessary to prevent mesh pinholes in aluminum alloy die-casting.
II.Dot pinholes in aluminum alloy die-castingparts: in the macrostructure The pinholes are round and dot shaped. The pinholes have clear outlines and are not connected. The number of pinholes per square centimeter area can be counted, and the diameter can be measured< Br/>III. Comprehensive porosity of aluminum alloy die castings: aluminum alloy die castings are intermediate types of punctate pinholes and reticulated pinholes. From the perspective of macrostructure, there are many large pinholes, but they are not round, and most of them are polygonal. It is recommended that you choosealuminum alloy die castingsproduced by some large manufacturers when purchasing, which can reduce the probability of purchasing pinhole die castings< Br/>In the production of aluminum alloy die castings, pinhole defects often occur, mainly including reticulated and dotted pinholes and comprehensive pores. Each pinhole will have more or less impact on the beauty, quality and performance ofaluminum alloy die castings. Therefore, pinhole problems must be prevented. The above is the introduction of Shuangcheng Hardware on the pinhole problem of aluminum alloy die castings. I hope it can help you p>
