FAQ
- About Us
1. Q: When was your factory established?
A: Our factory was officially established in 2008. We have been deeply involved in the flow metering field for 19 years, accumulating rich manufacturing experience and technological expertise. Our production base is located in the Hanguocun Industrial Park, Dunshang Town, Ganyu District, Lianyungang City, Jiangsu Province. This location boasts a superior geographical position, close to the port, with a complete supply chain and convenient transportation and logistics, providing a solid foundation for us to efficiently serve global customers.
- Qualifications and Strength
2. Q: What important qualifications and certifications does the factory possess?
A: Quality is our cornerstone. We have obtained and strictly implement the following system and product certifications:
- Quality Management System: ISO 9001 Quality Management System Certification, ensuring controllable production processes.
Product Certifications:
- China Type Approval Certificate for Metrological Instruments (CPA).
- GB/T 778 series certifications and factory inspection certificates conforming to Chinese national standards.
For export products, we possess core international certifications such as MID certification and CE certification.
- Metrological Standards: Our factory calibration laboratory is equipped with high-precision standard devices to ensure that the metering accuracy of each water meter meets international recommendations such as ISO 4064.
3. Q: What are our core advantages compared to our competitors?
A: Our advantages stem from our commitment to quality and innovation:
- Vertically Integrated Manufacturing: We possess a complete industrial chain from mold design, injection molding, machining to electronic module production, giving us strong control over quality, cost, and delivery time.
- Strict Quality Control: We implement full-process inspection from raw material warehousing to finished product delivery, with 100% testing of key processes (such as calibration) to ensure product reliability.
- Continuous R&D Investment: We focus on smart metering and sensing technologies, launching new market-adaptive products annually, such as low-power IoT water meters and ultrasonic water meters.
- Flexible Customization Capabilities: We can provide customized services in areas such as interfaces, communication protocols, and appearance according to customer needs.
- Global Project Experience: Our products have been operating stably in more than 30 countries and regions worldwide, withstanding the test of complex environments.
- Operations and Management
4. 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.
5. 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!
