FAQs: Blades & Fans for Automation Applications

Automation blades and fans are precision airflow components providing cooling for motors, drives, and electronics in industrial equipment. Types include axial fans with blade diameters from 50 to 600 millimeters moving air parallel to shaft axis, centrifugal impellers creating radial airflow for high static pressure applications, motor cooling fans integrated with electric motors, heat sink fans for electronics cooling, backward-curved blades for high efficiency, forward-curved blades for compact installations, mixed-flow fans combining axial and centrifugal characteristics, and custom blade assemblies including variable pitch fans and multi-stage impellers.

Aluminum alloy 6061-T6 and 2024-T3 contain the right balance of strength and weight allowing the construction of fans with rotational speeds exceeding 10,000 RPM, and are highly resistant to corrosion, easy to machine into complex fan blade profiles, and have superior thermal conductivity to help dissipation of fan heat. Engineering plastics like nylon and polycarbonate are very lightweight, reduce inertia, and are resistant to chemicals corrosion making them cost-effective to manufacture and insulate the fans electrically. At 304 grade, stainless steel is the maximum strength, it is corrosion resistant to harsh environments including washdown areas, and withstands millions of operating hours which is ideal for industrial fans. For composites, it is the ultimate weight reduction and the added strength, vibrations are dampened, and there is resistance to corrosion.

Using multi-axis CNC milling with optimized 3D blade designs for the airfoil geometry to maximize efficiency is made. For contour machining, the twisted blade surfaces with precise pitch angles to control flow are made. Boring is hub machining which creates the mounting hole at the center to fit the shaft and is controlled within the tight tolerance of ±0.003 inches. The mounting holes for assembly and the balance correction holes drilled into the fan are for coordinate drilling. To achieve balance grade G6.3, dynamic balancing is accomplished through material removal which causes a reduction in vibration. Surface finishing is done to reduce air turbulence and noise. For the volume manufacturing of plastic fans, the considerable investment in precision machining of the injection mold tooling is required.

We attain a blade profile tolerance of ±0.005 inches for airflow performance consistency, ±0.003 inches for hub bore tolerances to ensure proper fit of the motor shaft, blade pitch angles of ±1 degree for balanced thrust, dynamic balance grade of G6.3 or better with a residual unbalance of 2.5 gram-millimeters per kilogram at the working speed or lower, blade tip clearances and overall diameters controlled to ±0.010 inches to meet housing fit requirements, and ±0.010 inch tip clearances.

Yes, we provide rapid prototyping to verify fit and test assembly, with same-day CAD-to-part capability available for critical projects. For custom automation cells and research platforms, we perform low-volume production of 20 to 500 brackets. For standardized robot models, we perform high-volume production of thousands to tens of thousands of brackets annually, incorporating complete dimensional inspection, flatness verification, and material certifications.
