Stamping oil is a special lubricant used in metal stamping processes for lubrication, cooling, rust prevention and die protection. Its core function is to form a high-strength oil film under instantaneous high stress, reducing friction and wear, improving workpiece surface quality and extending die service life. It is suitable for processes such as blanking, drawing, bending and deep drawing. This article explains stamping oil in terms of its core functions, classification, selection and application, and development trends.
