Core Processing Technologies: Engineering for Fan Performance
Electric fan plastic parts demand precision to balance airflow efficiency, noise reduction, and structural strength. Goldcattle’s technologies ensure consistent performance across household, industrial, and commercial fans.
1. High-Precision Injection Molding
- Multi-cavity mold design: 4-32 cavity molds for fan blades/bases, achieving ±0.01mm dimensional tolerance. A 16-cavity ABS fan blade mold produces 10,000 units/day with uniform weight (±0.5g), ensuring balanced rotation and low vibration.
- Gas-assisted injection: For thick-walled parts (e.g., motor housings), this reduces warpage by 40% and cuts material usage by 15%. A PP fan base produced this way withstands 10kg load without deformation.
- In-mold decoration (IMD): Integrates logos/colors during molding, eliminating post-painting. A household fan control panel with IMD achieved scratch resistance (3H pencil test) and colorfastness (ΔE ≤1 after 1,000 hours UV test).
2. Mold Flow Analysis & Structural Optimization
- CAE simulation: Uses Moldflow to predict filling patterns, optimizing fan blade geometry for 10% higher airflow and 5dB lower noise. A 12-inch industrial fan blade redesign reduced turbulence via streamlined contours.
- Vibration analysis: FEA software ensures parts (e.g., motor housings) endure 5,000+ hours of 20-50Hz vibration without cracking, meeting IEC 60335 safety standards.
3. Surface Treatment & Functional Coating
- Anti-UV coating: Applied to outdoor fan grilles (PC material), resisting 3,000 hours of sunlight without yellowing or brittleness.
- Anti-static treatment: For industrial fans, reduces dust buildup on blades by 60% via 10^6-10^9Ω surface resistance, maintaining airflow efficiency.
- Texture finishing: Mold texturing (Ra 0.8-1.6μm) on bases and panels enhances grip and hides scratches, ideal for commercial fans in high-traffic areas.
4. Quality Testing for Fan Safety & Efficiency
- Dimensional inspection: CMM checks critical dimensions—blade thickness (±0.02mm), grille hole spacing (±0.1mm)—ensuring no airflow blockage or safety hazards.
- Balancing test: Fan blades undergo dynamic balancing (≤0.5g·mm imbalance), eliminating vibration and noise at 1,200rpm.
- Mechanical testing:
-
- Impact resistance (10J for grilles, no cracks)
-
- Heat resistance (80℃ for 1,000 hours, no deformation)
-
- Chemical resistance (cleaner/UV exposure for 24 hours)

Electric Fan Plastic Parts Machining Technologies
- Precision mold making: CNC EDM (±0.002mm) crafts complex blade contours, ensuring aerodynamic efficiency. A 3D-printed prototype mold for a new fan blade design cut development time by 40%.
- Automated injection cells: Robotic part removal and in-line weighing (±0.1g) maintain consistency, with 99.8% first-pass yield for mass production.
- Ultrasonic welding: Bonds multi-piece parts (e.g., grille frames) with 0.1mm seam accuracy, replacing screws to reduce assembly time by 30%.
Custom Electric Fan Parts Manufacturing Process
- Design & DFM: Engineers optimize client drawings (STEP/IGS) for moldability—e.g., adding draft angles to fan blades for easy demolding.
- Mold fabrication: CNC machining creates multi-cavity molds, with Moldflow validation to prevent defects like air traps.
- Injection molding: Automated machines produce parts with precise temperature/pressure control (e.g., 220℃ for ABS, 180℃ for PP).
- Post-processing: Surface coating, ultrasonic welding, or assembly (e.g., attaching blades to motor hubs).
- Quality validation: CMM inspection, balancing tests, and safety compliance checks (IEC 60335) ensure performance.
Custom Fan Plastic Parts Application Fields
- Household fans: ABS blades (12-16 inches), PP bases, IMD control panels for table/standing fans.
- Industrial fans: PC grilles (anti-UV), PBT motor housings for high-temperature environments (factories, warehouses).
- Commercial fans: Anti-static blades, stainless steel-reinforced bases for offices, shopping malls.
- Specialty fans: Waterproof PP parts for bathroom fans, flame-retardant ABS for kitchen exhaust fans.
Customization Capabilities: From Design to Delivery
- Design collaboration: Engineers refine blade curvature for maximum airflow (CFD-tested) or adjust base weight for stability (≥1.5x fan weight).
- Material flexibility: Choose between standard (ABS/PP) or premium (flame-retardant PC, anti-microbial PP) materials.
- Production scale: 100-500,000+ units/month—prototypes in 5 days, mass production in 2-3 weeks. A European client received 10,000 custom fan grilles in 15 days.
Common Processing Questions
- Q: How to reduce fan noise caused by plastic parts?
A: Optimize blade geometry via CFD (streamlined edges) and ensure dynamic balancing (≤0.5g·mm). A 16-inch fan’s noise dropped from 65dB to 55dB with these tweaks.
- Q: Can parts withstand high humidity (e.g., bathroom fans)?
A: Yes—PP with anti-microbial additives resists mold growth, and ultrasonic welding prevents water ingress. Tested to 95% RH for 1,000 hours with no degradation.
- Q: What’s the lead time for a new fan blade mold (10k units)?
A: 15-20 days for mold fabrication, 7-10 days for production. Rush options available with 24/7 machining.
- Q: How to ensure grille safety for children?
A: PC grilles with ≤8mm hole spacing (per IEC 60335) and rounded edges (Ra ≤0.05μm) prevent finger entrapment, tested via 50N force application.
