Quality Management System

A Brief Introduction of Quality Department
In order to comply with the demand of the company’s development, to guarantee the “high quality and unceasing improvement” of the product, Quality Department is equipped with multiple advanced testing instruments, guaranteeing complete testing equipment and testing instruments for each step including the reliability test of the products, from incoming quality inspection for raw materials to the outgoing quality inspection of finished products. The main testing instruments for raw materials are: Shanghai Tianpu gas chromatographic instrument, Jiangsu Tianrui EDX Energy dispersive spectrometer, Shanghai Anting automatic moisture titrator, Fuzhou Huazhi high precision electronic balance, Changji rotational viscometer, Tianjin Yonglida ISO1524 fineness gauge for scraper blade, etc. The main instruments for finished products inspection and reliability testing are : Zhenhua GX- ⊙600 vertical coating machine, Bainian Ceshi weather-proof ultraviolent test chamber, cold and heat impact testing machine, constant temperature and humidity machine, salt spray testing chamber, alcohol and rubber abrasion tester, Hualong HHF6 digital thermostatic water bath, standard light box, QuaNix coating thickness gauge, Ridao PHS-3C precise PH meter, RCA wear resistance testing machine, Xiangmin QCJ film impact tester, Xinhensen dip tester, vibration wear resistance tester imported from Germany, etc.   
Testing of Raw and Auxiliary Materials 
In control of the quality of the incoming materials, we have introduced or referred to inspection standard consistent with the international standard and adopted right inspecting method and instruments. We lead in new materials and new suppliers rigorously following the process, avoiding quality risks of the materials and the risk of environmental-hazardous substance. We have established full-time SQE, with whom we collaborate in R&D, sourcing development and management of suppliers, conduct routine audit and tutoring on suppliers to enhance the quality management ability of suppliers.
Process Control
In process control, systematic management method is adopted, complete and workable production operation process is established, and production process documents and all kinds of quality records are completely recorded, ensuring the uniqueness and traceability of each batch of products. We strengthen the management of the materials in use and idle stock, and adopt month color-coding method in storage material, which is intuitive and clear, guaranteeing first-in first-out. Leading ten- thousand-level dust-free plant is used as production plant of the company, which guarantees that the products are free from contamination. Automated blowing and canning system is adopted in feeding of production, along with full-time material controller and quality manager checking the name and quantity of the feedings, guaranteeing the accuracy of feeding. Process control is conducted strictly following “QC Engineering Drawing” on quality monitoring.
Finished Products Inspection and Reliability Testing
Having introduced or referred to the reliability standards of mobile phone manufacturers like Samsung, LG, Motorola, Huawei, Lenovo, Coolpad, millet, Jin Li, we established reasonable reliability testing criteria and testing method, guaranteeing that all the shipped products can reach the requirements of the client. According to the reliability testing criteria, we introduce all kinds of advanced supporting instruments and equipment, ensuring the stability and reliability of product quality. We are equipped with professional talent, who strengthen the daily management, Inspection, calibration and maintenance of the instruments, ensuring the accuracy of the results of inspection.
Exceptional Handling Scheme and Timeliness
The company, treating clients with the quality notion of “respect for the clients, mutual benefit and interaction”, established standardized management and control specially for early-stage development of clients, proofing control, technical service, complaint handling and so on; for example, before the development, we would visit the client repeatedly in order to know better of the client’ conditions like the line body; when making a proof, a full-time proofing engineer would follow up; during the production, engineers can be dispatched to follow up. The company adopts “7 days 24 hours all-weather response policy”, which means once received a complaint from client, the company ought to make response and come up with preliminary countermeasures in 1 hour; relevant personnel should contact the client directly or do investigation on the spot in person, start internal tracing at once, to find out the cause and enjoin the responsible department to make remedial measures and rectify within a time limit using the “8D” method, and respond to the client with detailed and effective rectification status according to the remedial measures in 24 hours, and make callback to the client in 48 hours and get ready to be re-checked by the client at any time, in order to win the client’s understanding.

It has established joint laboratory with Central South University, timely introduced world’s leading testing methods and means, organized training for relevant personnel, guaranteed the systematicness of technological development and the stability of product quality. The company adopts QCC, QIT methods to convene product quality meeting at regular intervals; under the guidance of the notion of “Keep improving, pursue for the better”, the company established an incentive system for improving proposals, in order to forge advanced coating products leading the direction of the industry.
