Does sheet metal part need lubrication?

In general, sheet metal parts themselves do not require lubrication as they typically do not come into direct contact with other components or engage in motion friction. However, in some cases, specific components of sheet metal parts may require lubrication, such as:
Moving parts: If sheet metal parts contain moving parts such as drawer guides, door hinges, etc., these parts may require appropriate lubrication to reduce friction and wear, ensuring smooth movement.
Contact surface: In some cases, the surface of sheet metal parts may require lubrication to reduce friction with other components. This is usually at connections that require frequent disassembly and assembly, such as bolts, nuts, threads, etc.
Anti corrosion: In specific environments, the surface of sheet metal parts may need to be coated with a layer of anti-corrosion lubricant or coating to prevent metal corrosion and oxidation.
When selecting lubricants, it is necessary to consider the environment and usage conditions of the sheet metal parts, as well as the compatibility between lubricants and materials. Lubricants such as lightweight lubricating oil, silicone grease, or lubricating grease are usually used. Lubricants should be used in moderation to avoid accumulation of impurities or excessive adhesion caused by excessive application.
