Air conditioner fan blade is manufactured by injection molding from engineering plastics, serving as core components in ventilation equipment such as blowers and HVAC systems. Its rotation generates airflow, facilitating air circulation.
Constructed from plastics including PP, ABS, FRP, polyurethane resin, PET, and nylon, air conditioner fan blade offers advantages such as lightweight construction, low cost, and corrosion resistance, making them ideal for indoor and outdoor applications in commercial, residential, and industrial settings.
Owing to the low melting point of plastics and their high malleability, fan blades can be engineered with enhanced aerodynamic properties. Examples include backward-curved or olive-shaped blades featuring complex surfaces, which effectively boost airflow volume and pressure while reducing energy consumption.
Our Mechanical Design services include complete structural design, Stack-up design, tolerance analysis, material selection DFMEAFM and DFA., one of Design Integrity’s most valuable tools in new product design is the failure modes and effects analysis (FMEA).
