2. Improving the pretreatment process and pretreatment fluid, reducing the equipment quantity and production cost has become the mainstream, and the stability, corrosion resistance, and environmental protection performance of the pretreatment fluid are constantly improving.
3. Focus on the development of new coatings, improve the general polyester, polyvinylidene fluoride (PVDF) and plastic sol to obtain the functional coatings of super color reproduction, ultraviolet resistance, sulfur dioxide resistance, corrosion resistance, pollution resistance, and heat absorption.
4. The equipments such as new welding machine, new roll coating machine, curing furnace and advanced automation instrument is much perfect now.
5. Cold embossing has become a trend because of its cheaper than hot embossing, its characteristics of beautiful appearance, stereoscopic feeling and high strength.
