The line adopts a multi-layer co-extrusion structure with independent temperature and speed control for each extruder, ensuring stable mixing and uniform distribution of three different materials or colors. Equipped with high-precision laser diameter measurement and real-time feedback adjustment, it guarantees extremely accurate diameter tolerance and excellent roundness. The stable cooling system and constant-tension winding system ensure smooth surface, consistent color layering, and reliable printing performance.
