In stretch process, lubricant quality and lubricant supplies whether sufficient to be affecting the wiredrawing mold's service life. Therefore the request lubricant oil base is stable, the oxidation resistance is good, has the fine lubricating ability, cooling and the clean, maintains the best lubrication condition throughout in the entire production process, with the aim of forming one to be able to withstand the high pressure, but is not destroyed the thin film, reduces the work area the friction force, enhances the mold service life.
Uses in the process, must observe the lubricating oil unceasingly the condition, if discovered that in the serious color deterioration or the lubricating oil the metal powder increases, must carry on the replacement or the filtration promptly, avoids the lubricating oil because of oxidizing the lubricity to reduce, simultaneously avoids drawing in the process tiny metal pellet damage mold.
