Designed for maximum output, stringent quality, and operational reliability, Huashida lines set the industry benchmark.

1. Plastic Sheet/Board Extrusion Line (For Base Material):

• Materials: PP, PE (HDPE, MDPE, LDPE), and blends.

• Applications: Base substrate layer for multi-layer heat-shrinkable sleeves, industrial sheets, construction panels, packaging.

• Key Capabilities:

  • Width Range: 500mm - 1600mm (Standard), up to 2500mm (Custom)

  • Thickness Range: 0.5mm - 6.0mm (Precision control ±0.05mm)

  • Output: Up to 1000 kg/h (Depending on material & thickness)

  • Core Tech: High-torque extruders, gear pumps for pressure stability, automatic die lip adjustment, precision calendaring/cooling, online thickness gauging (X-ray/IR), automatic winders/slitters.
    

2. Fiber-Reinforced Radiation Cross-Linked PE Heat-Shrinkable Sleeve Line (3-Layer Coextrusion):

• Structure:

  • Layer 1 (Outer): Radiation Cross-linkable PE (Protective, shrink layer)

  • Layer 2 (Middle): Fiber-Reinforced Cross-linkable PE (Structural reinforcement)

  • Layer 3 (Inner): Thermoplastic Adhesive (Sealing layer - EVA, Butyl, etc.)

• Key Specifications & Capabilities:

  • Sleeve Width: 150mm - 1500mm (Post-shrink, customizable)

  • Thickness Range: 1.2mm - 4.5mm (Total, layer-specific control)

  • Shrink Ratio: ≥ 3:1 (Standard), customizable ratios available

  • Reinforcement: High-strength polyester or glass fiber mesh/webbing (Integrated inline)

  • Radiation Cross-linking: Integrated inline Electron Beam (E-beam) irradiation system (Dose range: 80-200 kGy, precise control). Key for achieving high-temperature resistance, dimensional memory, and mechanical strength.

  • Output: High-speed production matching sheet line capacity.

  • Core Tech: Triple-layer coextrusion block/feedblock, precision melt laminating for reinforcement, controlled E-beam irradiation chamber, advanced corona treatment (optional for printing), precision cooling, tension control, servo-driven cutting/winding.
