This high-precision rotational mould is independently designed and manufactured by SUNMORE factory for one-piece rotomolding of HDPE blower casings and industrial fan housings. Made from premium cast aluminum alloy, it delivers excellent thermal conductivity, uniform heat distribution, and high dimensional accuracy for mass production of seamless, corrosion-resistant ventilation components.
Key Advantages
Uniform Wall Thickness
High-grade aluminum alloy ensures consistent heat transfer, eliminating uneven wall thickness for superior structural strength and vibration resistance.
Precision Surface Finish
CNC machining produces smooth, seamless blower casings with perfectly formed contours and functional openings for optimal airflow efficiency.
Easy Demoulding
Optimized split-type structure with precision positioning and quick-release clamps enables fast, damage-free demoulding and improved production efficiency.
Long Service Life
Professional anti-corrosion and anti-wear treatment maintains high precision and smooth surfaces through tens of thousands of production cycles.
Full OEM/ODM support for casing size, shape, air inlet/outlet positions, mounting flange design, reinforcing ribs, and surface textures
Structure
Split mould with reinforced frame, quick-lock clamps and standard rotomoulding equipment interface
Applications
Ideal for rotomolding production of HDPE blower casings, industrial fan housings, and ventilation equipment components. Widely used in industrial ventilation systems, workshop dust collection units, HVAC equipment, environmental protection machinery, chemical plants, warehouses, and other industrial air handling scenarios.
Selection Guidance
Choose This Mold When:
Mass production of high-quality HDPE blower casings and industrial fan housings is required
High-precision reproduction of complex curved contours and functional openings is needed
Seamless, corrosion-resistant casings with consistent wall thickness and structural strength are essential
Consider Alternatives When:
Small-batch trial production or simple-shaped designs are sufficient
Special-purpose blower housings with high-temperature or explosion-proof requirements are needed
Frequently Asked Questions
