Challenge
A new partner client reported widespread vibration issues in a batch of fan blade products.
As a crucial step in maintaining this important business relationship, we needed to swiftly and accurately resolve this complex technical issue while minimizing the impact on our customer’s sales operations.
Solution
Rapid Response and In-depth Analysis:
Immediately initiated an investigation, requesting the client to return samples for detailed testing.
Through rigorous testing, we discovered that 50% of the fan blades vibrated when paired with our stock motors.
Technical Cause Identification:
Our engineering team identified three possible causes of vibration:
- Improper fan blade calibration
- Excessive motor axis gap potentially causing resonance
- Overly long motor rear housing possibly leading to resonance from fan blade vibration
Systematic Solution Approach:
Reduced the motor axis gap and secured the motor rear housing screws to minimize resonance factors.
Precisely adjusted fan blade parameters based on the client’s samples.
Optimized the production process, especially the fan blade cooling and packaging stages, to prevent deformation due to temperature issues.
In-depth Quality Issue Tracking:
During the final pre-shipment test, we found 20% of the fan blades still exhibited vibration issues.
Immediately launched a comprehensive investigation, collaborating closely with the QC department and injection molding workshop supervisors.
Through detailed analysis of production records, we uncovered the root cause: to meet tight delivery deadlines, some fan blades were packaged before fully cooling, leading to slight deformation during transport.
This explained why these fan blades passed initial quality checks but showed vibration issues at the customer’s end.
Implementation of Comprehensive Improvement Measures:
- Optimized production schedules to ensure sufficient cooling time for each fan blade.
- Improved packaging methods to prevent deformation during transportation.
- Added extra cooling and quality inspection stages to the production line.
- Enhanced training for production staff to increase quality awareness.
Final Resolution:
Reproduced the affected fan blades, strictly adhering to new production and quality control processes.
Conducted multiple rounds of comprehensive testing before shipment to ensure 100% of products met quality standards.
Continuous Communication and Feedback: Maintained transparent communication with the client throughout the process, promptly sharing problem analysis and resolution progress.
