Product Overview
| The polycarbonate hollow panels produced by this PC Hollow Sheet U-shaped U Locked Sheet Extrusion Line feature a multi-wall or grid-like internal structure, providing exceptional impact resistance, reduced weight, and outstanding thermal insulation. With sheet thickness adjustable between 4 mm and 40 mm, widths up to 2,300 mm, and customizable lengths, the line is capable of meeting a wide range of application requirements and design specifications. PP can also be used as a production raw material. |
Equipment Composition
A complete PC Hollow Sheet U-shaped U Locked Sheet Extrusion Line typically consists of the following integrated units, each designed to ensure high precision, stable output, and excellent sheet quality:
Automatic Feeding & Drying System
Automatically conveys raw polycarbonate granules from storage to the extruder.
Equipped with a dehumidifying dryer to remove moisture and prevent defects such as bubbles or surface haze.
High-efficiency PC Hollow Sheet U-shaped U Locked Sheet Extrusion Line
Single-screw configuration designed for PC&PP material.
Features bimetallic barrel and screw for high wear resistance and extended service life.
Accurate temperature control zones ensure optimal plasticization.
Hydraulic Screen Changer & Melt Pump
Removes impurities to maintain sheet clarity.
Melt pump stabilizes extrusion pressure, ensuring uniform thickness.
Specialized Profile T-Die
Custom-engineered die head to form both the hollow sheet body and integrated U-shaped locking edges in a single pass.
Ensures precise profile dimensions and smooth surface finish.
Plastic Sheet Extrusion Machine Calibration Unit
Stainless steel vacuum table with precise positioning for profile shaping.
Multiple cooling sections to ensure sheet stability and dimensional accuracy.
Haul-off Unit
Synchronizes with the extrusion speed to prevent sheet deformation.
Designed to handle wide sheets (up to 2300 mm) without surface marks.
Anneal Oven (Stress-Relief Oven)
Installed after the cooling and haul-off section, the anneal oven gradually reheats the polycarbonate sheet to a controlled temperature, relieving internal stresses caused by the extrusion and cooling process.
This step is essential for PC hollow sheets with U-locked edges, as it improves dimensional stability, prevents warping, and ensures the panels maintain their precise profile during cutting, storage, and installation.
Cutting & Stacking Section
Automated cross-cutting according to preset lengths.
Stacking table for easy sheet collection and packaging.
Electric Control System
Centralized PLC control with touch screen interface.
Real-time monitoring of production parameters for consistent quality.
