Stretching oil is formulated with special additives such as high-molecular oiliness agents, oiliness enhancers, and extreme pressure anti-wear agents. It is applicable to the battery shell stretching forming process and plays a role in lubrication and cooling. It can effectively reduce the friction between the workpiece and the mold, lower the wear, and has a strong and tough oil film, which can effectively reduce the occurrence of scratches, cuts, sintering and welding, cracking and other phenomena.
Performance Features ：
- It has good lubrication performance, improves processing accuracy and protects molds
- It has good cooling properties and effectively prevents the formation of black sludge
- It is easy to clean after processing.
