PUSEN DECOR controls the quality of AKU acoustic wall panels through a full-process quality management system that focuses on raw materials, production precision, inspection, performance testing, and final delivery control.

First, raw material control is strictly managed. The MDF wood slats are tested for density, moisture content, and formaldehyde emission to ensure stability and indoor safety. The PET acoustic felt is checked for thickness, fiber uniformity, and weight consistency to ensure stable sound absorption performance across batches.

Second, production process control is applied during manufacturing. CNC cutting equipment is used to ensure accurate slat dimensions and consistent spacing. During assembly, industrial-grade adhesives are applied under controlled pressure and temperature conditions to ensure strong bonding between the wood slats and acoustic felt, reducing risks such as warping, detachment, or deformation over time.

Third, in-process and final inspections are carried out at multiple stages. These include incoming material inspection, in-production checks, and final product inspection. The main inspection points are dimensional accuracy, surface flatness, color consistency, and overall structural integrity to ensure uniform product quality.

Fourth, acoustic performance verification is conducted on selected batches. Testing is carried out according to standards such as EN ISO 354 to evaluate sound absorption performance using parameters like NRC or αw. This ensures the panels meet expected acoustic performance levels, typically Class D under standard installation, and can achieve higher performance when installed with optimized backing systems such as air gaps or insulation.

Fifth, environmental and safety compliance is ensured. The products are required to meet low formaldehyde emission standards such as E1 or E0 grade and may also undergo fire resistance testing in accordance with relevant building safety regulations to ensure suitability for residential and commercial applications.

Finally, packaging and shipment control ensures product protection during transportation. Each panel is inspected for surface defects such as scratches, dents, or color variations before packaging. Protective materials are used to minimize damage during shipping and handling.

Overall, PUSEN DECOR maintains AKU acoustic wall panel quality through strict raw material selection, precision manufacturing, multi-stage inspection, standardized acoustic testing, environmental compliance, and careful packaging control to ensure consistent quality in appearance, structure, and acoustic performance.
