As we all know, the physical properties of galvanized steel coils are the key index value for considering formability and are the key parameters for confirming and regulating the production process, so they should be given priority in production and processing.
When the appearance of parts is carried out in a complicated manner and the level of deformation capacity has a large, multi-pass molding should be selected. If multiple passes are formed, it will cause excessive deformation and destroy the total iron bond between the coating and the substrate. Based on factors such as abrasives, deformation characteristics, processing technology standards, production and handling, when the gap is set to take into account the thin and thick coating set the appropriate gap. Most of the coatings can be made as solid lubricants and can be carried out considering the wetting provisions of most of the molding technology processing production processes of the company. Some Chinese architectural coatings can enhance the wettability of the plating according to their own regulation recipe, such as the wettability of the plating is not enough, can enhance the wettability according to smear oil, wax, cover can be detached from the original film and so on. But should pay special attention to the wet lubricating liquid is very easy to absorb waste, should be eliminated before installation, can be removed from the original film was removed as soon as possible after the end of construction should be carried out. Should be based on the machine equipment situation, processing process standards, parts look like and other elements to set an effective production and processing rate, deformation rate is too large very easy to cause the galvanized steel coil coating off. The flexibility of the plating layer is reduced at low temperatures, thus ultra-low temperature production processing should be prevented. If the working temperature is low, the raw material should be heated up to the required temperature before the production process is carried out.
