About Stamping Solutions

In the past, when producing deep-drawn or heavy-drawn workpieces, everyone believed that pressure-resistant (EP) lubricants were the best choice for mold protection. Sulfur and chlorine EP additives have a long history of being mixed into neat oils to improve mold life. However, with the emergence of new metals, high-strength steel, and strict environmental protection requirements, the value of EP oil-based lubricants has decreased and even lost market.
In the molding of high-strength steel at high temperatures, EP oil-based lubricants lose their properties and are unable to provide a physical mold protection membrane in extreme temperature applications. The extreme temperature type IRMCO high solids polymer lubricant can provide the necessary protection. As the metal deforms in the stamping die and the temperature continues to rise, the EP oil-based lubricant will become thinner and in some cases will reach the flash point or burn (smoke). IRMCO water-based stamping lubricants generally start with a much lower consistency when sprayed on. As the temperature rises during the forming process, it becomes thicker and tougher. In fact, high-molecular polymer extreme temperature lubricants have "heat-seeking properties" and will stick to the metal, forming a diaphragm that can reduce friction. This protective barrier controls friction and metal flow by allowing the workpiece to stretch without cracking or bonding during the most demanding part forming operations. It effectively protects the mold, extends the service life of the mold, and improves the strength of stamping.
