High Repeatability Tungsten Carbide Lip Slot die

Presented by Naoki Rikita, MMC Ryotec

Tungsten Carbide, which is known for its hard metal properties, is used on slot die lips for wear resistance. Computer analysis introduces a case study of lip wear for critical process control. This study helps in understanding geometric modeling of slot die lips and helps support the necessity of wear resistant material for slot die lips. Additionally this analysis shows the resulting cases of protection against corrosive fluids. This result shows the necessity of Tungsten carbide lip including sharp edge on the lip.

MMC Ryotec, Mitsubishi Materials first experimented and began applying Tungsten Carbide to traditional slot dies in 1975.
