Recognized by the Ministry of Industry and Information Technology! Yuchai's Reliability Improvement Technology Won the National Award

 This typical case collection and selection activity for improving the quality of industry and information technology focuses on machinery.、Electron、Key core products in key industries such as automobiles，It aims to enhance the quality management capability of industry and information technology.、Promoting the Innovation and Application of Quality Technology、Improve product reliability level，Find out in time、Sum up、Promote a number of advanced experiences with strong demonstration.。

“Development and Application of Key Technology of Green High Strength and Toughness Cast Iron”This case is mainly through the improvement of mechanical properties、Shrinkage cavity of casting、Loose problem，Balancing material performance and product quality，Castings with good performance consistency are cast.，It is Yuchai's mature practical experience in quality improvement based on the project.。The case not only breaks through the bottleneck of high strength and toughness cast iron material technology and processing technology，It solves many key technical problems in the preparation and processing of high performance cast iron.，It also creates the technology of modified silicon carbide integrated eutectic nickel element strengthening cast iron.、The key technology of industrialization of nitrogen element solid solution strengthening gray cast iron was broken through.，It has formed a complete set of original core technologies and series of products.，For the implementation“The carbon reaches the peak”“Carbon neutral”The goal of double carbon is of great significance.。

In recent years，Yuchai insists on quality“Zero defects”，Fast upgrade of combined product technology、Customer demand diversification and other needs，Build and continuously improve clear in the process、Clear quality requirements and quality standards，In the product project、Design、Research and development、Testing, verification and product release, etc.，There are clear quality requirements and actions.，And form a quality gate.，Ensure effective implementation of quality requirements and quality standards，The quality effect is remarkable。
