With the wide application of CNC machinery, especially the automatic paint sprayer equipment is increasingly recognized by many customers. But regardless of the automatic paint sprayer equipment or manual spray, some customers always encounter the problem of coating peeling off. Let some customers don't know how to solve it. In fact, customers who know and are familiar with the common knowledge of automatic paint sprayers and paints can easily avoid this problem.
