Air Conditioner Fan Blade Mould
SINO Mould specializes in custom precision injection moulds for air conditioner fan blades, professionally manufactured for plastic fan blades matching household wall-mounted air conditioners, cabinet air conditioners, mobile air conditioners, fresh air systems and cooling & heating fans. Different from ordinary small household appliance fan blade moulds, we conduct special mold flow optimization and structural upgrading for the core requirements of air conditioner fan blades including thin-wall curved surface, high-precision dynamic balance, low noise and high concentricity, targeting the blade curve radian, blade root stress area and shaft sleeve matching position. Adopting conformal balanced cooling and hot runner multi-point glue feeding molding solution, it thoroughly solves common industry problems such as shrinkage, warpage, deformation and uneven thickness of thin-wall fan blades. The molded fan blades feature smooth burr-free surface and consistent blade radian with qualified dynamic balance precision. Compatible with high-quality PP/ABS engineering plastics, this mould supports 2/4/6 cavities customization. Equipped with an integrated automatic demoulding structure, it requires no secondary trimming and calibration, perfectly meeting the mass production and high-precision production demands of household and commercial air conditioner fan blades, effectively improving production efficiency and reducing customers’ subsequent sorting and processing costs.

Air Conditioner Fan Blade Mould Core Advantages
- Special molding structure for thin-wall curved surfaces: Optimized cavity structure targeting the characteristics of air conditioner fan blades such as large curved surface, thin wall and easy deformation, ensuring full and flat blade forming without depression, shrinkage or warpage, guaranteeing the concentricity of fan blade operation and reducing operating noise fundamentally.
- Blade conformal surrounding cooling channel system: Adopting fan blade exclusive conformal cooling channels, which accurately cover the core areas of blades, blade roots and shaft sleeves with overall temperature difference ≤3℃, realizing uniform and rapid cooling, greatly improving molding stability and avoiding dimensional deviation of batch products.
- Multi-point balanced glue feeding system: Multi-cavity mould adopts independent balanced runner design with highly unified pressure, flow rate and temperature in each cavity. The weight difference of multi-cavity products is ≤0.02g, ensuring excellent dynamic balance consistency in batch production without manual secondary calibration.
- High wear-resistant mirror cavity process: The cavity adopts high-quality mould steel hardening treatment and mirror polishing process, delivering finished products with high surface finish, no scratches or flow lines and no need for secondary trimming. It is wear-resistant and non-sticky during long-term high-speed mass production.
- Modular split insert design: Blade cavities, shaft sleeve positions and positioning inserts are independently split and can be disassembled and replaced separately. It is convenient for modification and maintenance of fan blade radian and size, greatly reducing mould modification and maintenance costs and shortening downtime.
- Full-process CAE mold flow simulation analysis: Accurately predict molding defects such as air trapping, shrinkage deformation and weld lines before mould opening, optimize runners and exhaust structures in advance to reach standards after one mould test, effectively shortening mould delivery and mass production cycle.
- Comprehensive personalized customization service: Support adjustment of fan blade quantity, radian angle and thickness parameters, customize exclusive flame-retardant, mute and high-air-volume structures, and support customer LOGO and pattern engraving to meet the production needs of all categories of air conditioning equipment.
