Quality is the lifeline of a company. We have established a strict quality inspection system covering the entire chain of "supplier admission → incoming material inspection → assembly testing → factory inspection → after-sales tracking".
1. Quality certification and standards
The company strictly implements the ISO 9001:2015 quality management system, and all exported products are certified according to customer requirements or internationally recognized standards (such as CE, UL, RoHS, etc.). All cooperative factories have corresponding industry qualifications, and we regularly conduct re audits and on-site audits of suppliers.
2. Supplier admission audit
Every new supplier must undergo a comprehensive review by our technical quality department, including production capacity assessment, sample testing, process document review, and on-site/remote factory inspection. Only suppliers with qualified ratings can enter the qualified list.
3. Incoming Quality Control (IQC)
After all purchased components arrive, they undergo random or full inspection of appearance, dimensions, materials, and key performance indicators in accordance with the inspection manual, and data is recorded. Unqualified batches shall be returned and traced for rectification.
4. Process Inspection (IPQC)
During the assembly and system integration process of self-developed products, there are multiple quality control nodes, including electrical safety testing, airtightness testing, flow/pressure calibration, environmental aging testing, etc. Each node must be signed and released by a quality engineer before entering the next process.
5. Factory Inspection (FQC)
Each finished product undergoes 100% functional testing and visual inspection before shipment, and a Chinese and English version of the inspection report is issued. The testing content covers performance parameters, communication interfaces, protection levels, insulation withstand voltage, etc., to ensure that the product fully meets customer order requirements.
6. Packaging and transportation inspection
Qualified products shall be protected and packaged according to standard packaging specifications, and the integrity of the packaging and the correctness of labeling shall be rechecked. For vulnerable parts or high-value equipment, additional vibration testing or simulated transportation verification should be added.
7. After sales quality tracking
Establish customer quality records and conduct traceability management for each batch of products. For customer feedback issues, initiate the 8D reporting process, identify root causes, and develop corrective and preventive measures to continuously improve product quality and service levels.
8. Main testing equipment
The company's own laboratory is equipped with the following equipment:
Air tightness leak detector (accuracy 0.1 Pa)
High and low temperature humid heat test chamber (-40 ℃~150 ℃)
Pressure/flow calibration table (accuracy level 0.05)
Insulation withstand voltage tester
Data Collection and Analysis System
Vibration test bench
Through these strict quality inspection processes, we ensure that every product delivered to our customers meets or even exceeds their expectations, winning the trust of global customers with solid product quality.
