High Light High-Accuracy Needle Punched Nonwovens Production Line ,600~2000 g/㎡ Automotive Battery Bottom Guard Plate Production Line ,5~50 m/min Continuous Filament Spunbond Needle-punched Underbody Shield Production Line
Continuous Filament Spunbond Needle-punched Underbody Shield Production Line
Process Principle

PET sheet melt spinning → continuous filament air stretching → swaying filament laying → pre-needling + main needling for consolidation → heat setting → edge trimming and winding, obtaining three-dimensional filament needled felt, and delivering it to the molding process to manufacture battery underbody shield plates.

Production Line Equipment Composition
  • Raw material transportation and drying system: PET sheet storage bin, transportation, crystallization drying (PET must be fully dried to prevent filament breakage during spinning)
  • Extrusion and melt filtration: Screw extruder, melt filter, static mixer, ensuring stable melt pressure and temperature
  • Spinning box + spinneret: Double-row spinning components, producing continuous PET filaments
  • Air stretching system: Slit/tube high-speed air stretching, stretching filaments to enhance fiber orientation and strength (core unit for underbody shields)
  • Cooling + swaying filament laying device: Side wind cooling with swaying mechanism that randomly lays filaments into an even fiber net, controlling surface density uniformity
  • Needling unit (pre-needling + main needling): Pre-needling for initial entanglement and fiber net fixation; main needling for high-density needling to enhance thickness, tear resistance, and puncture resistance
  • Heat setting machine: Eliminates internal stress, stabilizes dimensions, and controls molding shrinkage rate (critical for battery shield plates)
  • Storage, edge trimming, tension control
  • Automatic winding machine + online thickness/weight detection
  • PLC centralized control system: Integrated control of temperature, pressure, speed, and stretching air pressure throughout the production line
Technical Parameters (Automotive Battery Underbody Shield)
Parameter Specification
Raw Materials PET / COPET dual-component options (dual-component offers better toughness and molding performance)
Finished Product Weight 600~2000 g/㎡ (common range for underbody shields)
Working Width 3.0m (mainstream, customizable)
Single Filament Fineness 5.0~6.0 dpf
Production Line Speed 5~50 m/min
Annual Production Capacity Up to approximately 4000 tons/year
Product Characteristics High impact resistance, heat resistance, sound absorption and noise reduction, strong molding deformation ability, 100% recyclable
Product Features (Battery Underbody Shield Substrate)
Three-dimensional filament structure provides higher longitudinal and transverse strength, superior tear resistance, and better stone impact resistance compared to short-fiber needling, offering comprehensive protection for battery pack bases
Porous structure combines insulation with sound absorption properties
Excellent thermal stability reduces cracking risk during molding processes
Lightweight design replaces some metal shield plates, contributing to vehicle weight reduction
Environmentally friendly and fully recyclable, meeting new energy vehicle material requirements
