Although stainless steel drums produced by manufacturers of such drums are also roller-type products, just like idler rollers, their maintenance is relatively simpler compared to that of idler rollers. They are also all used in standard printing tasks involving separation*, but it’s obvious to anyone with a basic understanding that there is a difference between idler rollers and stainless steel drums. The significant difference between the stainless steel drums produced by manufacturers and the idlers lies in the fact that the surfaces of the idlers are engraved with pattern textures, whereas stainless steel drums do not have such features. The quality of idlers depends on the level of detail and precision of the engravings on their surfaces. To assess the technical skill of stainless steel drum manufacturers, one can examine the surface finish of these drums; the higher the surface finish, meaning the smoother the surface, the more advanced the manufacturing skills of the manufacturer, and vice versa. Under the effects of heat and rolling forces, the original repair areas on stainless steel rollers exhibit differences in glossiness, and this is something that sheet metal manufacturing companies cannot tolerate. The only solution is to remove the chromium layer from the surface of the stainless steel drum, and then manually repair it using material of the same type ； Then electroplating is carried out, and stainless steel drums are manufactured. However, there are some requests regarding stainless steel drums that are quite strict: it is not allowed to use the meat-replenishing method; instead, the damaged areas of the stainless steel drum must be ground away, followed by electroplating to achieve a polished finish. Shanghai drum manufacturers advise that when selecting stainless steel drums, one should consider the three factors mentioned above: surface finish, hardness, and material quality. Only when all of these parameters meet the basic requirements can the drum be purchased; otherwise, it cannot be bought if even one of them does not meet the standards. After choosing the right manufacturer and product for the stainless steel drum, it is also necessary to implement certain maintenance measures during its use, so as to ensure that it performs excellently. Since the surface of the stainless steel drum has no patterns, there is no need to clean the dirt within those patterns; it is sufficient to maintain the shine of the drum’s surface as it was originally, while also paying attention to rust prevention. For example, during the wetter seasons, the stainless steel drums that are not in use should be covered with plastic film to prevent moisture from seeping into them and causing rust.
