We would like to introduce the "measuring" process in our mold manufacturing process. In the measurement process, which is essential for ensuring the quality of mold components and molded products, measurement equipment installed in a climate-controlled measurement room monitors final measurements and daily variations. By observing our current status with advanced microscopes, we are committed to improving quality and precision throughout the entire process.

We would like to introduce our "High-Speed Machining and Assembly" in the mold manufacturing process. Using two high-speed machining centers from Sugino Machine, we achieve time reduction through direct engraving and polishing elimination, as well as the production of high-difficulty electrodes. In the final assembly process, we handle complex molds that are often avoided within the industry using advanced fitting techniques.
