Heated with a stainless steel heating element, featuring a four-sided circulation hot air structure and an electronic speed controller for adjustable speed. Double-layer thermal insulation panels prevent the surrounding environment from becoming too hot. Imported high-temperature-resistant thermal insulation fabric significantly reduces heat loss. The conveying chain uses solid roller shafts, wrapped with high-temperature-resistant silicone tubes, capable of handling heavy loads. Imported components ensure the stability of the equipment. Suitable for PVC, PE, POF shrink film.
