Recognized by the Ministry of Industry and Information Technology of the People's Republic of China! Yuchai's reliability improvement technology has won a national award

This collection and selection activity for typical cases of quality improvement in industry and information technology focuses on key core products in key industries such as machinery, electronics, and automobiles. It aims to enhance the quality management capabilities of industry and information technology, promote the application of quality technology innovation, improve the reliability level of products, and promptly discover, summarize, and promote a batch of advanced experiences with strong demonstration significance.

The case of "Key Technology Development and Application of Green High-Strength and High-Toughness Cast Iron Materials" mainly balanced the material performance and product quality by improving mechanical properties, shrinkage cavities and porosity in castings, and cast castings with good performance consistency. It is a mature quality improvement practical experience of Yuchai based on the project. The case not only broke through the technological bottlenecks in the process and processing of high-strength and high-toughness cast iron materials, solving many key technical problems in the preparation and processing of high-performance cast iron, but also created the technology of modified silicon carbide integrated co-solubilized nickel element strengthened cast iron and broke through the key technologies for the industrialization of nitrogen element solid solution strengthened gray cast iron, forming a complete set of original core technologies and series of products. It is of great significance for achieving the dual carbon goals of "carbon peak" and "carbon neutrality".

In recent years, Yuchai has adhered to the principle of "zero defect" in quality. In light of the rapid technological upgrades of its products and the diversified demands of customers, it has established and continuously improved clear and definite quality requirements and standards in its processes. In every link from product project initiation, design, research and development, testing and verification to product release, there are clear quality requirements and actions, and a quality gate has been formed Ensure that quality requirements and standards are effectively implemented, and achieve remarkable quality results.
