Automatic PET Strap Extrusion Line 300kg/h 90mm Screw Water Cooling High Accuracy
The Automatic PET Strap Extrusion Line is engineered for mid-size converters who want consistent quality with minimal operator intervention. A 90mm single screw, automatic PLC control and water cooling system work together to hold a steady 250-300kg/h output while keeping strap dimensions within tight tolerances. The line is designed around high accuracy thickness control, so every coil leaving the winding station has the same profile, strength and appearance, which is exactly what automatic strapping machines and quality-conscious buyers expect.
Key Features
- Automatic PLC Control: The control system manages barrel temperatures, screw speed, haul-off tension and winding parameters automatically, with preset recipes for fast product changeover.
- High Accuracy Thickness Control: Closed-loop haul-off regulation and precision gear pumps keep strap thickness uniform across the full 6-15mm width range.
- Water Cooling Efficiency: The water cooling circuit stabilizes the melt temperature and protects sensitive PET resin from thermal degradation during continuous operation.
- 250-300kg/h Output: The 90mm screw delivers a dependable 250-300kg/h extrusion rate, perfectly matched to medium-volume strap production.
- 38CrMoALA Durable Screw: The hardened 38CrMoALA screw resists abrasion from recycled PET and PP feedstock, extending service life and reducing downtime.
- Easy To Operate Interface: A clear touch screen with diagnostic messages lets operators monitor the whole line at a glance and respond quickly to any alarm.

Applications
This line serves strap producers supplying the carton, textile, brick, ceramic and agricultural industries. It manufactures PET strap for semi-automatic and automatic strapping machines used in palletizing and bundling, as well as PP strap for lighter packaging duties. The automatic control system makes it suitable for workshops with limited skilled labor, while the high accuracy output ensures trouble-free feeding through high-speed strapping heads. Customized color and customized voltage options are available, and the water cooling system keeps the production hall cooler during hot weather, improving both machine stability and operator comfort.
Packaging & Quality Assurance
The line is packed in reinforced wooden export cases with stretch film wrapping, foam cushioning and clear handling instructions. All movable parts are secured before packing to prevent transit damage. Each machine undergoes a no-load test and a full inspection of electrical systems, safety devices and mechanical alignment prior to shipment. We include an English operation manual, wiring diagram, installation video and free online technical support, with optional on-site commissioning available. Inspection reports and test videos are provided on request for your peace of mind.
