Designed for high-quality production, it features a fully submerged drawing basin for optimal wire cooling and lubrication, and staggered cone pairs to ensure a straight wire path and superior surface quality. Productivity is enhanced through the intuitive NMI color touchscreen interface, while its robust construction with helical precision gears promotes smooth operation. The machine delivers exceptional energy efficiency, reducing electrical consumption, lubricant usage, and maintenance costs through extended service intervals. With a capacity for up to 17 drafts and a production speed of 40 m/s, the M 31 is optimized for copper wire processing with finished diameters ranging from 0.35 mm to 1.6 mm. This professional documentation provides technical specifications, machine design highlights, and performance capabilities essential for industrial wire manufacturing
