Which factory can do die-cast aluminum oxidation treatment.aluminum sheet fabrication

　　Which factory can do die-casting aluminum oxidation treatment, in fact, it is normal to say that aluminum alloy die-casting want to do oxidation treatment is OK, but oxidation treatment will be black and gray, what is the cause?

　　Mainly aluminum alloy material has a high silicon content, and when oxidizing, it is easy to have a chemical reaction, so the color of oxidation will be black and gray, and the luster is very poor. At present, with the continuous improvement of aluminum alloy die-casting technology, people's requirements for product quality are also constantly improving, more customers want to improve the process to improve product quality, so how to meet such a demand?

　　In fact, in the die-casting aluminum oxidation process is also constantly improving, to do a good job of aluminum alloy die-casting oxidation, we must scientifically master the mold of the flow channel technology, die-casting process and post-processing methods, with this series of strict control process, can ensure the smooth production of oxidation quality. This includes: mold runner, gate planning, mold temperature control; The use of materials, generally can be ht412 die-cast aluminum special ash removal agent to remove the surface black ash, to avoid pollution elements; Die casting process control, reduce water marks and black watermarks; Pre-blank processing; Anode surface treatment plant selection and so on.
