Stainless steel plate manufacturers covering film on the surface of production why production? Stainless steel plate production often use silk screen printing or printing technique is made and be become, through the metal signs in the printing process is made and be become colourful appears very upscale - - - - - - - Why > sign manufacturers in the production of stainless steel surface film to cover? Stainless steel plate production often use silk screen printing or printing technique is made and be become, through the metal signs in the printing process is made and be become colourful look very high-end, but also has a disadvantage that is in the process of installation or transportation vulnerable to external scraping the polishing effect makes the metal on the surface of a paint fall off. So in this context, stainless steel plate production is used in metal plates covered a layer of film to protect the metal plate on the surface of the paint, in ensuring that the metal panels in the case of relatively 'safe' will be the film off again. The technological requirements of the stainless steel plates manufacturers production of stainless steel plates: 1, stainless steel plate must be planed pit bending welding ( Stainless steel plate must be planed pit after bending, to ensure that the edge straight degrees) ; Ensure the bending of circular arc Angle R < 1 mm. 2, to remove surface oil before welding, reduce weld forming virtual welding, such as porosity defect. 3, after completion of welding will all visible weld grinding smooth, as well as the surrounding surface smooth, no obvious weld mark.
