Aluminum die-casting is a common metal processing method that can be used to manufacture various aluminum alloy components, such as automotive engine components, aviation engine components, electronic equipment casings, etc. Next, we will introduce the process of aluminum die-casting processing.
-
Aluminum die-casting is a common aluminum alloy casting technology with good processing performance and strength, widely used in aviation, automotive, electronics, machinery and other fields. In the process of aluminum die-casting, selecting appropriate aluminum alloy materials is crucial for the quality and performance of the product. So, how do professional aluminum die-casting manufacturers choose suitable aluminum alloy materials?
-
Aluminum alloy die-casting products are mainly used in electronics, automobiles, motors, home appliances and some communication industries. Some high-quality aluminum alloy products with high performance, high precision and high toughness are also used in industries with high requirements such as large aircraft and ships. The main use is still in the parts of some instruments. Sand holes and other defects sometimes appear in the production process, so how to avoid sand holes in aluminum alloy die casting?
-
The reason of shrinkage and shrinkage defects in Dalian aluminum die casting processing is that the liquid shrinkage and solidification shrinkage of metal are larger than the solid shrinkage. When performing sequential solidification, the liquid metal cannot be replenished in the solidified area, and holes will be formed. Large and concentrated holes are called shrinkage holes, and small and dispersed holes are called shrinkage holes. Prevention methods are:
