FAQ
Operations and Management
1. Q: How does the factory conduct effective production planning and inventory management?
A: We adopt a model combining digitalization and lean production:
- Demand-Driven Planning: We develop master production plans based on sales forecasts and customer orders (especially project orders), and dynamically adjust them through the ERP system.
- Scientific Material Classification: We maintain safety stock for general-purpose parts (such as cases and standard movements); for special-purpose and customized parts, we implement "buy-to-order" procurement to minimize inventory costs and risks.
- Lean Manufacturing Process: Implementing cell-based production and Kanban management reduces work-in-process inventory, shortens production cycles, and improves responsiveness to market changes.
2. Q: How do you handle customer complaints and quality issues?
A: We view customer feedback as a valuable opportunity for improvement and strictly implement the following closed-loop process:
- Rapid Response and Recording: Upon receiving feedback, contact the customer immediately and record detailed information such as the problem description, product batch, and usage environment.
- Professional Analysis and Localization: Return the problematic product to the laboratory for systematic disassembly and testing to accurately pinpoint the cause (e.g., measurement errors, component failure, external water loss, etc.).
- Transparent Communication and Resolution: Provide the customer with a written analysis report, clearly defining responsibility. If the issue is our responsibility, immediately initiate a replacement or repair plan and trace back to other products in the same batch.
- Root Cause Correction and Prevention: Enter the problem into the quality management system, initiate root cause analysis, and take corrective and preventative measures in design, process, or workflow to prevent recurrence.
We firmly believe that high-quality products and reliable service are the foundation of cooperation. If you have any specific questions or special needs, please feel free to contact our sales or technical team!
