Project Background
A professional industrial packaging manufacturer in Romania focuses on producing high-tensile PET strapping bands for steel coil, timber, and brick packaging. In daily production, the client faced severe quality bottlenecks with traditional extrusion equipment. Conventional PET strap extrusion machines lacked precise calibration functions, resulting in inconsistent strap thickness, uneven surface flatness, and unstable tensile strength. The thickness deviation often exceeded ±0.05mm, leading to a high defective rate and frequent customer complaints. Moreover, unqualified straps could not meet EU industrial packaging standards, limiting the client’s high-end market expansion. The factory urgently upgraded to a precise calibration PET strap extrusion machine with uniform thickness to stabilize product quality and improve market competitiveness.
Customized Machine Solution
CHANGZHOU UNITED WIN PACK CO.,LTD delivered a customized PET strap extrusion machine for strap fabrication featured with high-precision digital calibration system. Different from ordinary extrusion lines, this equipment adopts closed-loop pressure and thickness automatic adjustment technology, which real-time monitors and calibrates extrusion parameters during continuous operation. It effectively controls the PET strap thickness tolerance within ±0.02mm, achieving fully uniform thickness and consistent mechanical performance for every finished strap.
The intelligent PLC control system supports one-click parameter setting for different strap widths (9mm, 12mm, 16mm, 19mm). Operators can complete specification switching and precision calibration without shutting down the machine, greatly improving production continuity. Meanwhile, the optimized extrusion die structure eliminates surface streaks, bubbles and uneven melting problems, ensuring smooth and flat PET strap appearance suitable for high-standard industrial packaging scenarios.
Project Achievements & Client Feedback
After the new machine was put into formal operation, the client’s PET strap defective rate dropped by 30%, and product qualification rate reached 99.8%. All finished straps stably meet EU quality standards, helping the client successfully enter the local high-end industrial packaging supply chain. The precise calibration design greatly reduced manual testing and adjustment workload, saving labor costs and improving daily output efficiency. The client highly recognized our equipment precision and stable performance, and signed a long-term equipment cooperation agreement.
