Product Features:
Densely arranged tiny round micro holes achieve stable sound absorption performance, effectively reducing noise reflection. Lightweight aluminum base reduces load for ceiling and wall installation, convenient for transportation and construction. Smooth hole inner surface avoids dust accumulation and is easy to clean. Multiple perforation arrangements including straight row and hexagonal staggered row are optional. The aluminum plate can be cut, bent, welded, sprayed and anodized to satisfy diversified design demands. Natural anti-corrosion property suits long-term indoor and outdoor application.
Precision micro punching equipment guarantees consistent tiny hole diameter and neat hole distribution. Every finished panel will go through flatness inspection, dimensional calibration and aperture testing before delivery. Small sample orders are acceptable for acoustic effect testing. Factory direct sales eliminate intermediate links with favorable bulk pricing. Our technical team can adjust hole diameter, hole spacing and open area to match targeted noise reduction and ventilation requirements. Deep processing such as punching mounting holes, frame edging and surface coating is available.
Application Scenarios:
Acoustic engineering: office sound-absorbing ceiling, conference room noise reduction panels, auditorium wall cladding; Electronic industry: equipment heat dissipation shell, dust isolation net, speaker grille; Construction decoration: indoor partition panels, facade decorative aluminum sheets; Other fields: ventilation filters, lighting lampshades.
Production Process:
Aluminum sheet incoming inspection → leveling stress relief → CNC micro tiny round hole punching → deburring treatment → surface cleaning → optional anodizing or powder coating → fixed-size cutting → finished quality inspection → protective film covering → kraft paper wrapping → fumigated wooden pallet packaging for sea shipment. QC staff strictly supervise all production procedures.
