When getting magnesium alloy die casting parts, some people have questions because they do not understand the casting steps. They do not know how to deal with the quality of the casting better during pickling and what the overall polishing requirements of the casting are. So do you also have these questions? Now let's explain it to you.
The pickling of magnesium alloy die castings must be well controlled, as excessive pickling can lead to erosion of the casting surface, but it cannot be achieved if insufficient pickling is performed. Therefore, the above problems need to be well controlled and avoided. Before painting, the phosphating primer should be applied first, so that the top coat has a good brushing effect. In addition, there are basic requirements for the polishing of magnesium alloy die casting. Specifically, the polishing should be fine, complete, without dead corners or omissions. This can make the casting surface smooth and glossy, avoid rust, erosion and other problems.
The above are the requirements of pickling and polishing of magnesium alloy die casting parts. I think you have more understanding of it. Thank you for your browsing.
