Quality Management

Since 2003, Tanyun has started to construct its quality management system following the requirements of ISO9001 and initially formed the quality control management system, which emphasized on documentation, routinization and process. In 2005, in order to develop and produce military weapon equipment, Tanyun built the national military-standard quality management system based on the GJB9001A-2001: Quality Management System Requirement and submitted the certification application. Regarding the annual examination of quality management system as the way of making continuous improvement on quality management, Tanyun regularly organizes internal examination of quality management system. Through the internal examination, the company can find the problems and insufficiency from the current QM system. The company also raises requirement in the annual management examination meeting and follows the execution situation of requirements and advice collected in the meeting, the latter of which can guarantee the effectiveness of the advice. In the routine production activities, Tanyun strictly follows the requirements of national military-standard quality management system and controls the development of production and service of the products to meet the legal requirement and to satisfy customers’ needs. By evaluation, Tanyun identifies customers’ needs, analyze the execution risks, take effective action to avoid or to lower the risks. To track the quality and the using status of delivered products, the company regularly visits customers and studies market development, product development and customers’ expectations on products and services. Also, by conducting the satisfaction survey, Tanyun collects customers’ feedback, pays great attention to their user experience to helps them improve products and services continuously. According to the production needs, the company adopts the monthly purchasing plans and temporary purchasing plan (if necessary) and conducts annual evaluation on suppliers to guarantee the quality of the raw material. The production process strictly sticks to the ideas of “Strict, Specialized, Specific and Stable”, and organizes self-examination, crossed-examination and special examination. The qualified products will be delivered to the warehouse and examined regularly during storage period. The products will be checked again before delivered to the customers.


According to factors of experiment and transportation, Tanyun divides materials into significant materials (Type A materials) and ordinary materials (Type B material).
