High-Efficiency PE PP Sheet Production Line from Qingdao Qinghang

In modern industrial manufacturing, high-performance plastics are replacing traditional materials at an unprecedented pace. To meet the growing global demand for premium industrial plates, Qingdao Qinghang Plastic Machinery Co., Ltd. offers its state-of-the-art PE/PP plastic sheet production line. Engineered for efficiency, stability, and high output, our manufacturing equipment converts Polyethylene (PE) and Polypropylene (PP) resins into heavy-duty plastic sheets with a thickness range of 3mm to 30mm and custom widths ranging from 500mm to 3000mm.

Advanced Technical Configuration of Our Plastic Extrusion Machinery

Our fully automated extrusion line integrates cutting-edge technology to ensure flawless, continuous operation from raw material feeding to the finished product:

• Vented Single-Screw Extruder: Designed specifically for high-efficiency melt homogeneity and excellent degassing performance to eliminate moisture and ensure flawless internal structure.

• Automated Feeding & Mixing: Equipped with an advanced material blender and a screw-driven automatic feeding system to guarantee precise formula control and reduce labor costs.

• Coat-Hanger Extrusion Die: Features optimized internal flow channel geometry for uniform, stable melt distribution across the full sheet width.

• High-Precision Three-Roll Calender: Utilizes a dedicated specialized heavy-duty reduction gearbox. The roll temperatures are independently modulated using precise mold temperature controllers, ensuring ultimate surface gloss and perfect flat tolerances.

• Integrated Downstream Automation: Combines cooling brackets, edge-trimming/slitting devices, a protective film lamination unit, a transverse cutting machine, and an automatic pneumatic stacker into a cohesive, smart processing line.

Industrial Applications and Market Demand for Heavy-Duty PE Sheets

Polyethylene (PE) sheets produced by our machinery are widely sought after across heavy industries due to their remarkable chemical resistance, high impact strength, and low friction coefficient. Through professional CNC cutting and fabrication technologies, these sheets are tailored for critical components in:

• Chemical & Environmental Engineering: Highly corrosion-resistant tanks, chemical containers, and vessel linings.

• Mechanical Engineering: Wear-resistant conveyor guides, star wheels, gears, and structural machinery plates.

• Logistics & Transportation: Heavy-duty truck bed liners, vehicle interior wear plates, and industrial cargo dunnage.

• Electrical & Packaging Sectors: High-insulation barrier sheets and robust protective backing boards.
