Quality Management
The cornerstone of quality, a zero-defect commitment.
Quality is not something that is inspected into existence—it is designed and produced. We have established a quality management system that covers the entire process and involves all employees, embedding exceptional quality into every stage, from raw materials to finished products, thereby providing absolutely reliable assurance for your mobile phones, consumer electronics, and automotive electronic products.
Certification and System Framework
Our company has established and continuously operates a comprehensive management system centered around the quality management systems ISO 9001 and IATF 16949 (for the automotive industry), ensuring product quality and traceability. At the same time, we have integrated the ISO 14001 environmental management system and the ISO 45001 occupational health and safety system. This underscores our commitment not only to delivering zero-defect products but also to fulfilling our responsibilities toward the environment and society, as well as safeguarding the health and safety of every employee. This fully integrated system framework enables us to achieve synergistic development in quality, environmental protection, and safety while serving industries such as automotive and consumer electronics, making us a reliable, compliant, and sustainable supply chain partner for you. Furthermore, in response to the specific requirements of different industries, we strictly adhere to regulations such as RoHS 2.0 and REACH, as well as customer-specific standards, ensuring that our products meet global market access requirements.
Full-process quality control
Incoming material inspection:
Conduct rigorous testing on substrates, chemicals, and other materials, establish a supplier assessment system, and eliminate risks at the source.
Process inspection:
First-piece inspection:Before starting each shift and for each product, a mandatory inspection must be conducted to confirm that the parameters match the standards.
Patrol inspection:Quality control personnel conduct frequent spot checks on key process parameters—such as the concentration of chemicals, temperature, and film thickness—as well as semi-finished products, and record the results on SPC control charts.
Self-inspection:Train operators to perform self-inspections and mutual inspections, fostering a quality awareness among all employees.
Final inspection
100% of finished products undergo critical performance testing, and random inspections are conducted according to AQL standards. Only合格 products are allowed to proceed to the packaging stage.
Advanced detection and experimental capabilities
We are equipped with industry-leading testing equipment, providing robust data support for quality assurance.
Online Monitoring

Traceability
Through the deep integration of ERP (Enterprise Resource Planning) and MES (Manufacturing Execution System), we’ve achieved end-to-end digital management—from customer orders to workshop execution. ERP is responsible for “managing the company,” ensuring that our resources and decision-making are optimized; MES, on the other hand, is tasked with “managing production,” guaranteeing that every mobile phone and automotive component coming off our production lines is manufactured in a transparent, controllable, and traceable manner. This is precisely what underpins our strong commitment to quality and delivery reliability.
