Multi Zone Heating Oven PP Strapping Band Extrusion Machine With Uniform Hot Air Circulation

Heat setting is the core process determining the final crystallinity, dimensional stability, and strength of PP strapping. This production line features a multi-zone independently controlled setting oven combined with a high-efficiency forced hot air circulation system. The system creates a highly uniform and stable thermal field within the 4-meter-long oven, eliminating temperature dead spots and ensuring precise process temperatures at every stage of heat treatment. This uniform and controllable thermal environment is essential for achieving high product performance and low thermal shrinkage.
