In the manufacturing process of automobile aluminum hub, the spraying process is a very key link. By strengthening the quality control of the spraying process, it is not only conducive to make the appearance of the aluminum hub more beautiful and generous, but also more important to avoid the corrosion of pollutants in the driving environment of the automobile on the hub, and extend the service life of the wheel. Among them, the spraying process of automobile aluminum alloy wheel hub includes powder spraying process and spray painting process.
1、 Powder spraying technology
Powder spraying is the first process in the spraying process of aluminum wheel hub. Its main function is to cover flat and prevent corrosion. The spraying thickness of 100 μ M can effectively improve the performance of the aluminum wheel hub, make the aluminum wheel hub better adapt to the driving environment, improve the driver's safety and prolong the service life of the aluminum wheel hub. In the spraying process of aluminum wheel hub, powder spraying can effectively cover the defects on the surface of aluminum wheel hub, which is conducive to the smooth development of the next process. The continuous powder spraying production line includes heat energy system, curing furnace, chain conveying system, recycling system, powder spraying room and powder spraying gun, etc. According to different manufacturers, there are some differences in the relevant standards, which should be determined reasonably according to the actual situation of the wheel. There are a variety of powder to choose from, epoxy powder focuses on corrosion prevention, polyester powder focuses on weather resistance, epoxy polyester powder is also a more commonly used powder, organically combines the advantages of the two. In the process of practice, we should make a reasonable choice according to the actual needs of customers and the actual situation of aluminum hub production. In addition, before the manual powder spraying, we should strengthen the training of construction personnel, improve their professional ability, and ensure that the staff have mastered the powder spraying technology before they start to work, so as to ensure the quality and effect of powder spraying.
