Addressing Exposed Copper Wires in Industrial Fan Motors

At SF Electrical Appliance, safety is at the core of everything we do. We understand that even the smallest oversight in manufacturing can lead to potential risks, which is why we prioritize quality control and safety inspections.

Challenge: Exposed Copper Wires in Motor Connection Caps

During our routine pre-shipment inspection, our quality control team discovered an issue with exposed copper wires inside the motor connection caps of some industrial fans. This posed a significant risk of electrical leakage and safety hazards, which could have impacted the safety and reliability of our products.

Solution: Immediate Action and Process Optimization

Step 1: Batch-Wide Inspection

Upon identifying the issue, we conducted a thorough inspection of all remaining finished products in the affected batch to determine the scope of the problem.

Step 2: Root Cause Analysis

We traced the issue back to a specific production process and identified the worker responsible for installing the motor connection caps. By understanding the root cause, we could address the problem effectively.

Step 3: Rework and Team Training

• Reworking Products: All affected products were reworked to ensure there were no exposed wires, completely eliminating any risks of electrical leakage.
• Training the Production Team: We provided additional training for the production team to reinforce the importance of safety in every assembly step.
• Enhanced Quality Protocols: We updated our inspection protocols to catch similar issues earlier in the production process.

Impact: Ensuring Safety and Reliability

By taking immediate action and resolving this issue before shipment, we:

• Eliminated any risks of electrical hazards for our customers.
• Reinforced our commitment to delivering high-quality, safe products.
• Strengthened customer trust in SF Electrical Appliance’s safety-first approach.
