Dongyuan’s quality control system is kept active throughout the whole process of our business activities, from R&D to delivery. During the R&D stage, we put emphasis on the evaluation of the structure, even make experiments for sure. Any, hidden defect will be refused, for the benefits both of our users and of ourselves. According to the Chinese standard of sample procedures for inspection GB2828 (an equivalent of ISO2859 or MUL-STD-105D), we make careful incoming inspection for sufficient items with professional instruments.

In production process, we control technique procedure and workmanship, issue work instructions for every process, make itinerating inspection to every working position. Process control is our powerful tool for the qualification rate and homogeneity of the final products. Dongyuan was accredited by ISO9001 standards in 1996, with experience in the operation of quality control systems for over 10 years.Dongyuan also has other certifications such as ISO14001, QC080000 and TS16949 which further improve our key management skills and controlled process.

For the finished products, a random sampling drawn in proportion to the total amount will be sent to the QA departments, for parameter measuring, performance testing, power capacity testing and aging testing. We can not leave a snake in the grass.
