In building HVAC, industrial exhaust, and cleanroom projects, ductwork serves as the core channel for airflow, and its cross-sectional shape directly affects system resistance, space occupancy, and installation efficiency.

In modern architecture, especially in the design of commercial offices, high-end residences, and public spaces, interior ceiling height has become a crucial indicator of spatial quality.

The fatigue life prediction of PVC composite aluminum foil tube requires a systematic analysis combining material properties, dynamic pressure characteristics and environmental factors.

To meet the noise reduction needs of single-layer louver vents, we need to start from three aspects: airflow organization optimization, structural vibration reduction and material upgrade.

Raw material pretreatment is the basis of the extrusion process. The drying and mixing uniformity of PVC resin directly affects the melt fluidity.

The rounded edges of the blades must also be coordinated with the overall structural design of the blinds to maximize the noise reduction effect.
