1. Product Introduction
The market changes rapidly, and product demands are increasingly diverse. Our production line is designed as a powerful "multi-format platform," not a single-product dedicated machine. By quickly changing modular dies, flexibly adjusting the process parameter chain, and accommodating various winding solutions, you can efficiently switch between producing PET products of different widths (e.g., 5mm to 30mm), thicknesses (e.g., 0.3mm to 2.0mm), and even cross-sectional shapes (e.g., flat strap, monofilament, rectangular bar) on the same line. This flexibility greatly expands your business scope, helping you capture market opportunities with faster response times and lower equipment investment, enabling agile, small-batch, multi-variety production.
2. Main Specifications
Modular Die System: Employs a quick-change die connection system with multiple sets of dies (e.g., 1-out-2, 1-out-4, 1-out-6, different lip shapes), enabling product changeover within hours.
Adjustable Haul-off & Stretch Units: Haul-off roller width and nip are adjustable; draw ratios are infinitely variable over a wide range to suit the mechanical properties required by different products.
Configurable Cooling & Setting Paths: Cooling roll layout or water tank guide paths can be adjusted according to different products' cooling needs.
Flexible Winding Solutions: Options for single-spindle, dual-spindle, or multi-position winders to accommodate different roll weights and packaging requirements.
Universal Control System: The control system features a wide parameter setting range and multiple recipe storage capacities for easy management of different product processes.

4. FQA:
Q1: Switching from narrow strap to wide sheet—what needs adjustment besides the die? Is it complex?
A1: Main adjustments include: 1) Changing the die and flat die lip for the corresponding width. 2) Adjusting cooling roll spacing and contact angle for uniform cooling of the wide sheet. 3) Resetting tension parameters for haul-off and winding, as total tension is higher for wide sheets. 4) Possibly adjusting the stretching process. This procedure is covered in our training and SOPs, and our control system supports saving a separate "wide sheet" recipe, making the switchover process streamlined and repeatable, not complex.
Q2: With one line doing so many specifications, will it be a jack of all trades, master of none?
A2: No. "Versatile" does not mean "compromised." The line's core precision platform (temp control, speed control, tension control) is high-standard. When switched to a specific product, we use dedicated dies and a process recipe optimized for that product to achieve its best performance. Like a high-performance camera with different lenses for various subjects, our line platform ensures excellent foundational performance, while dedicated dies and recipes ensure each "subject" is mastered.
