First, high quality base plates are used, and the requirements for surface, shape and dimensional accuracy of the base plates are getting higher and higher. For outdoor use, such as small zinc flake flat hot-dip galvanized steel coils, non zinc flake flat hot-dip galvanized steel coils, and zinc alloy hot-dip galvanized steel coils emerging in time; For indoor use, such as galvanized steel coils, film coated cold-rolled sheets and aluminum coils. Color coated plate company
Second, improve pre-treatment process and pre-treatment solution. With less equipment and low cost, it has become the mainstream process, and constantly improve the stability, corrosion resistance and environmental protection performance of pre-treatment solution.
Third, pay attention to the development of new coatings, and improve general polyester, polyvinylidene fluoride (PVDF) and plastic sol to obtain super color reproducibility, UV resistance, sulfur dioxide resistance, and corrosion resistance; Development of pollution resistant, heat absorbing and other functional coatings.
Fourth, the unit equipment is more perfect. For example, new welding machines, new roller coating machines, improved curing furnaces, and advanced automatic instruments are used.
Fifthly, cold embossing production technology has become a development trend due to its lower cost than hot embossing, beautiful appearance, stereoscopic feeling and high strength.
