Sound Insulated Flexible High Speed Door Pin Type Noise Reduction For Spraying

Traditional pin‑type flexible stacking door focuses on wind‑resistance and large‑span performance, with ordinary single‑layer fabric without obvious noise‑reduction function. This sound‑insulated version adds composite sound‑absorbing interlayer inside curtain, achieves noise‑isolation effect for sandblasting, spraying and impact‑noise workshops. Still no‑ground‑rail design, convenient for large work‑pieces and equipment to pass in and out. It is a targeted solution for environmental‑protection noise‑control requirements of heavy‑industry workshops.

Multi‑layer composite sound‑absorbing insulated curtain, outer layer adopts wear‑resistant waterproof PVC‑polyester fabric, inner equipped with high‑density sound‑absorbing interlayer; optimized‑load pin‑arranged galvanized steel truss wind‑resistant beams; heavy‑load side guide rails; heavy‑duty frequency‑conversion electric hoist lifting system adapting to thick‑curtain weight; wire‑rope lifting mechanism; anti‑fall safety locking device; double‑limit travel control; infrared safety photocell and acousto‑optic alarm; optional sound‑insulated transparent observation window; manual emergency release under power‑off condition.

• Multi‑layer composite sound‑absorbing curtain, realize noise‑isolation for high‑noise workshop working condition
• Retain pin‑shape overhead stacking, no ground‑rail, flat ground for large‑workpiece free passage
• Truss‑beam structure optimized for thickened composite curtain, guarantee wind‑resistance and running stability
• Curtain outer‑layer fabric: waterproof, wear‑resistant, anti‑aging, adapt to spraying‑sandblasting workshop environment
• Complete safety protection: anti‑fall locking, double‑limit, infrared obstacle detection, acousto‑optic warning
• Support custom noise‑reduction grade, door‑opening dimension and sound‑insulated observation window

Truss beam cutting‑welding and anti‑rust treatment → composite sound‑insulated curtain hot‑welding compound processing → pin‑type beam‑curtain assembling → heavy‑duty hoist matching and installation → safety anti‑fall device fitting → control cabinet wiring → whole‑door cycle debugging → noise‑insulation performance inspection → export packing.

Composite curtain sound‑insulation performance test; fabric tensile‑strength inspection; truss‑beam welding and load‑bearing verification; whole‑door lifting cycle test; anti‑fall locking simulation test; safety‑device full‑function checking before shipment.

• Large sandblasting and shot‑blasting workshop super‑large access doorway
• Large‑size spraying booth and anti‑corrosion painting workshop
• Heavy‑impact noise‑intensive manufacturing plant outer gate
• Semi‑open industrial workshop needing noise‑isolation treatment
• Environmental‑protection‑oriented heavy‑industry factory large‑span passage

Reserve sufficient overhead headroom above doorway; steel‑structure wall shall bear increased total weight brought by sound‑insulated composite curtain; reserve power supply for hoist and control cabinet. We provide complete technical drawings for local installation team to finish on‑site assembly.

Prevent sharp objects from scratching curtain surface to avoid damaging internal sound‑absorbing interlayer. Clean curtain surface dust regularly. Check truss‑beam welding point, wire‑rope abrasion and fastening bolts every 6‑12 months. Periodically inspect anti‑fall safety locking device; replace aged curtain and worn accessories timely.
