Main Equipment:

SMT pick-and-place machine, reflow oven, wave soldering machine.

Common Issues:

Cold solder joints/false soldering, short circuits, control panel button failure.

Process 5. Final Assembly

Key Processes:

Assembling all manufactured components (motor, blades, grille, base, control panel, etc.) into a complete electric fan.

Main Equipment:

Automated assembly line, screwdrivers, jigs.

Common Issues:

Cable pinching/compression, fan blade-grille rubbing.

Process 6. Fan Blade Matching Inspection

Key Processes:

Precise matching inspection of installed fan blades for dimensions, weight, and balance to ensure perfect fit with the motor and other components, reducing vibration and noise.

Main Equipment:

Precision measuring instruments, dynamic balancing machine, visual inspection system.

Common Issues:

Poor dynamic balance, dimensional/weight mismatch, visual defects.

Process 7. Safety Testing

Key Processes:

Conducting electrical safety tests on the assembled electric fan, including insulation withstand voltage, grounding resistance, leakage current, etc., to ensure compliance with safety standards.

Main Equipment:

Withstand voltage tester, grounding resistance tester, leakage current tester.

Common Issues:

Substandard insulation resistance, poor grounding, excessive leakage current, withstand voltage test failure.

Process 8. Function & Performance Testing

Key Processes:

Comprehensive testing of the electric fan's functions (e.g., wind speed adjustment, oscillation, timing) and performance indicators (e.g., air volume, noise, power consumption) to ensure the product meets design requirements.

Main Equipment:

Air volume tester, noise meter, power meter, life test bench.

Common Issues:

Oscillation function failure/sticking, inaccurate timer function, excessive noise, excessive power consumption, substandard life test.

Process 9. Appearance Check, Cleaning & Packaging

Key Processes:

Final inspection of product appearance to ensure no scratches, stains, or other defects; cleaning, then packaging according to specifications, labeling, and preparing for warehousing or shipment.

Main Equipment:

Inspection fixtures, cleaning equipment, packaging machine, carton sealing machine.

Common Issues:

Appearance defects, incomplete cleaning, incorrect/missing labels, missing/incorrect accessories.

7. How V-Trust Controls Electric Fan Quality

V-Trust delivers comprehensive Electric Fan inspection services, ensuring consistent product quality and regulatory compliance. Our quality control solutions cover all stages of Electric Fan, including Sample Checks, Production Monitoring, During Production Inspection, Pre-Shipment Inspection, and Container Loading Supervision, reducing the risk of product failures and costly recalls.

Sample Check

Our engineers meticulously evaluate electric fan samples to assess motor performance, blade balance, noise levels, and overall build quality. We verify compliance with client specifications for airflow, power consumption, and safety features like grille spacing.

Production Monitoring

We provide on-site monitoring during electric fan production to track assembly quality, ensuring correct motor installation, secure blade attachment, and proper wiring. This helps intercept issues like loose connections or inconsistent oscillation mechanisms early.

During Production Inspection (DPI)

Conducted when at least 10% of the electric fan order is completed, this inspection helps detect early-stage problems such as motor noise, unstable bases, or cosmetic defects on housing. It allows for timely correction, reducing rework and potential delays.

Pre-Shipment Inspection (PSI)

A thorough final inspection before shipping to confirm:

• Overall product quality and functionality (e.g., all speed settings, oscillation, remote control)
• Compliance with specifications (e.g., dimensions, power rating, safety markings)
• Cosmetic integrity (e.g., no scratches, dents, or misaligned parts)
• Accurate quantity, proper packaging, and correct labeling

Container Loading Supervision (CLS)

Verification of product quantity, proper loading, and secure positioning of electric fans in containers to prevent shifting, crushing, or damage during transit. Packaging integrity and protective measures are also checked.
