Stability is fundamental to high-speed production of premium quality PP strapping. This production line features an advanced dual-stage cooling system comprising a primary cooling tank and secondary sizing tank. The primary tank performs initial quenching and shaping, while the secondary tank delivers precise low-temperature cooling following stretching and oven heat treatment. This dual-stage process guarantees permanent dimensional stability, minimal internal stress, and superior product rigidity.
Both tanks incorporate polyurethane-covered guide rollers and precision alignment devices that maintain parallel advancement of all four strands. This innovative design eliminates product entanglement and deviation during high-speed operations, creating optimal conditions for subsequent embossing and winding processes.
