Solutions For Stamping Parts
In the past, when producing deep-drawn or heavy-drawn parts, pressure-resistant (EP) lubricants were considered the best choice for protecting dies. Sulfur and chlorine EP additives have been mixed into pure oil to improve die life for a long time. However, with the emergence of new metals-high-strength steel-and stricter environmental requirements, the value of EP oil-based lubricants has decreased, and they have even lost their market share.
In the high-temperature forming of high-strength steel, EP oil-based lubricants lose their performance and cannot provide a physical protective barrier for dies in extreme-temperature applications. Extreme-temperature IRMCO high-solids polymer lubricants, on the other hand, can provide the necessary protection.
As the metal deforms in the stamping die, the temperature rises continuously, and EP oil-based lubricants tend to thin, sometimes reaching their flash point or even burning (smoking). IRMCO water-based stamping lubricants are generally much less viscous when first sprayed. They become thicker and tougher as the temperature rises during the forming process.
In fact, high-polymer extreme-temperature lubricants have "thermal-seeking properties" and adhere to the metal, forming a barrier that reduces friction. This protective barrier allows the workpiece to stretch without cracking or sticking during the forming of the most demanding workpieces, thereby controlling friction and metal flow. It effectively protects the mold, extends its service life, and improves the strength of the stamping process.
