In response to the recent response from Tianjin Jinhu Tire Co., Ltd., which did not apply excessive plastic return in accordance with the requirements of the technology and technology, the Chinese Rubber Industry Association issued the “Circular on Tire Enterprises Conscientiously Implementing Process Discipline to Ensure Product Quality.†Tire companies earnestly learned from the lessons of the Tianjin Jinhu incident, strengthened enterprise process management, and severely disciplined the process. The concept of quality first was applied to all aspects of production to provide users with safe and reliable tire products.
The China Rubber Association put forward the following opinions on tire companies: First, to further strengthen the awareness of quality, to improve the quality of production personnel through the professional training and the implementation of the requirements of the technology and technology regulations; to conduct a major inspection of the technology and technology regulations, plug the loopholes, and improve and improve; Strengthen all basic work, and implement the advanced 6S management methods, strengthen process management, and strict process discipline as important measures to conscientiously and quickly grasp.
The second is to further revise and improve the technical regulations for tires developed by the company. Under the premise of strict implementation, the inspection and rewards and penalties shall be strengthened so that the company's process execution rate can meet the specified requirements. In order to further strengthen the level of self-discipline in the industry, the Association intends to organize the development of a new version of the “Regulations and Inspection Methods for Several Techniques for the Process of the Carcass Tire†industry self-regulation.
Thirdly, tire manufacturers must infer anything from the inspection of raw materials, inspection of semi-finished products, inspection of finished products to inspection of finished products, and do not leave dead ends, truly standardize and standardize all production processes, and produce tire products that users can be assured of satisfactory.
In addition, the association will also strengthen product quality credit and brand recommendation work, so that the concept of "quality is the life of the enterprise" is more deeply rooted.
