Product details

Product Description

The DBPC-T1750 Twin Screw Single Layer PET Sheet Extrusion Machine is driven by servo motors and controlled by a PLC system with data calculation and alarm functions, ensuring stable and intelligent operation. Featuring a twin-screw extrusion design, it is specially developed for PET sheet production and supports recycled materials without the need for a pre-crystallization drying system, delivering excellent plasticizing performance with low energy consumption. The modular screw structure allows easy maintenance and replacement, while the dual vacuum venting barrel effectively removes moisture. A melt pump stabilizes extrusion pressure, ensuring uniform sheet thickness and consistent high-quality production.

Machine Features

		1. Feeding Unit Two independent hoppers are used for virgin and recycled materials. The mixing ratio can be adjusted through feeding speed control, or materials can be pre-mixed by a mixer and then automatically fed into both hoppers for stable and consistent supply.

2. Twin Screw Extrusion Unit The machine adopts a twin-screw extrusion system with an independent water-cooling temperature control system, ensuring stable plasticizing performance and precise temperature regulation.

		3. UnitHydraulic Screen Changer & Gear Pump Unit A hydraulic screen changer enables fast and efficient impurity filtration, while the gear pump ensures more precise and stable melt extrusion for improved sheet quality.

4. T-Die Extrusion Unit Molten plastic is evenly extruded through the die head, and different die widths can be selected to produce sheets of various sizes.

		5. Three-Roll Calendering Unit The three rollers are controlled by an external constant-temperature system and require preheating to maintain stable processing conditions. Each roller is independently driven by a servo motor for precise thickness control.

6. Haul-Off Unit The traction system pulls the sheet at a constant and stable speed after forming, ensuring smooth and uniform production.

		7. Slitting Unit The slitting device trims edges and can cut wide sheets into narrower products, improving product flexibility and finishing quality.

8. Waste Edge Rewinding Unit Trimmed waste edges are automatically collected and rewound to maintain a clean and efficient production environment.

		9. Silicone Coating System Silicone oil is applied by dripping onto the middle roller and evenly distributed across the sheet surface through the pressure of the rear roller.

10. Drying Oven Unit Two drying ovens are used to dry the silicone coating thoroughly, ensuring proper sheet dryness and stable final product quality.

		11. Double Station Rewinding Unit The dual rewinding stations use pneumatic shafts and cylinder push-out design to enable fast roll changes and continuous production.
