Stamping oil plays a key role in the stamping process. Good cooling performance and extreme pressure and wear resistance have made a qualitative leap in the service life of the mold and the improvement of the accuracy of the workpiece. Depending on the material of the workpiece, the performance focus of the stamping oil is different when it is selected.
- 1. Silicon steel plate is a material that is easier to punch. Generally, for the cleaning of the workpiece, low-viscosity punching oil is used on the premise of preventing punching burrs.
- 2. When selecting stamping oil for carbon steel plates, the best viscosity should be determined according to the difficulty of the process, the method of drawing oil and degreasing.
- 3. The galvanized steel sheet chemically reacts with chlorine-based additives, so when choosing stamping oil for galvanized steel sheet, attention should be paid to the problem of white rust that may occur in the chlorine-based stamping oil.
- 4. The stainless steel plate is a material that is prone to hardening. It requires the use of high oil film strength and anti-sintering tensile oil. Generally, stamping oil containing sulfur and chlorine compound additives is used to avoid problems such as burrs and cracks on the workpiece while ensuring the extreme pressure performance.
