Description
Strength Through Stretch: The PET Line Engineered for Performance
Engineered Stretching Technology
Our PET production line is engineered around the core principle of high-tension, high-precision stretching. Every component—from the reinforced frame foundation to precision-balanced stretch rollers, high-torque servo drive systems, and wear-resistant surface treatments—is designed to withstand continuous high-load operations. This engineering ensures deformation-free, vibration-free performance that reliably produces high-quality PET products.
Key Specifications
  • Structural Engineering: High-rigidity box-beam frame optimized through finite element analysis to prevent deformation under long-term high-tension loads
  • Core Components: Alloy steel stretch rollers with quenching, tempering, grinding, and hard chrome plating for surface hardness above HRC 60
  • Drive System: High-power servo motors with precision gear reducers delivering smooth, responsive torque
  • Bearings & Guides: High-precision P5 grade bearings and wear-resistant tenter frame rails
  • Thermal Management: Internal hot oil circulation system maintaining roller surface temperature uniformity within ±1°C

Frequently Asked Questions
What is the practical value for customers of the heavy mechanical structure and high-precision components?
The value manifests in long-term stability, low maintenance costs, and superior product quality. A robust structure resists vibration and prevents process parameter drift caused by micro-deformation. High-precision rollers and bearings ensure smooth operation, reduce wear, extend equipment overhaul intervals, and directly contribute to product thickness uniformity and surface quality. This represents an investment focused on total cost of ownership over the equipment lifecycle.
What are the advantages of using servo motors to drive stretch rollers compared to ordinary motors with VFDs?
Servo motors offer significant advantages in stretching applications: High Control Precision enables extremely accurate speed and position control, ensuring absolute accuracy of draw ratios. Extremely Fast Response provides millisecond-level reaction to tension changes, complementing closed-loop tension control systems. Strong Overload Capacity withstands short-term overloads several times the rated value, handling instantaneous production shocks. High Efficiency and Low Heat Generation ensure top-tier performance and reliability throughout the stretching process.
