Project background: mass production qualification rate fluctuates
As a well-known domestic drive motor manufacturer, its new generation permanent magnet synchronous motor faced significant fluctuations in product qualification rate during the mass production ramp-up stage due to micro-leakage problems in the cooling system, which became a bottleneck restricting quality and delivery.
Technical challenges:Traditional methods encounter bottlenecks
Inefficiency:The traditional water detection method is slow and can easily cause secondary damage to the motor, affecting production continuity.
Difficulty in positioning:Microleakage is difficult to locate accurately, and the average troubleshooting time exceeds 90 minutes, slowing down the pace of the production line.
The beat doesn’t match:Existing detection methods cannot meet the rhythm requirements of high-speed production lines, which restricts the release of production capacity.
Solution: HM Series Helium Mass Spectrometry Leak Detection System
In order to overcome the problem, the company introduces Hai RuisiHM-400Helium mass spectrometry leak detection system, equipped with special docking tooling and automated transmission system to realize motor assembly100%Online, full inspection.
Accurate and efficient:The system has high sensitivity and can stably detect small leaks, avoiding missed detections and misjudgments.
Seamless integration:The automated loading, unloading and transmission system ensures that the inspection rhythm perfectly matches the high-speed production line.
Data traceability:Supports docking with MES system to realize automatic recording, storage and traceability of detection data, providing data support for quality improvement.
Implementation results:A double leap in quality and efficiency
The detection accuracy rate has been increased to 99.95%, and the false positive rate has been reduced to less than 0.05%.
Troubleshooting time is shortened to less than 15 minutes, and efficiency is increased by 85%
Perfectly matches the rhythm of high-speed production lines, increasing production capacity by 25%
Annual quality cost reduced by approximately RMB 3.5 million
Core benefits:
Quality improvement: Product reliability is significantly enhanced and after-sales risks are significantly reduced.
Efficiency jump: Production capacity has been effectively released, strongly supporting the delivery of market orders.
Cost optimization: Quality cost savings are directly converted into corporate profit margins.
