Does the landlord want to do aluminum business? Electrophoresis is around 5800, and the processing cost is slightly different in different regions. Now Ye Wei is packed with cold shrink film, which is not very cost-effective. This material is a second-line product of the same grade as Weichang, but the service is not as good as Weichang. If possible, make high-quality materials, such as Mei Jian, Xingfa, Fenglv, Chonglv, Asia and Jinqiao. I hope the landlord can make big money.
