First Prize for QC Group Achievements
Recently, the 9th Central Enterprise QC Group Achievement Presentation Competition, guided by the State owned Assets Supervision and Administration Commission of the State Council and hosted by the China Association for Quality, successfully concluded in Changzhou. The QC team's achievement of "improving the qualification rate of brake housing quality" submitted by China Yituo has won the first prize in the competition after multiple rounds of fierce competition. In addition, in the 2026 Luoyang QC Group Achievement Presentation Competition, seven achievements submitted by China Yituo, including "reducing the non conformance rate of cylinder oil passage cleanliness", "reducing the user feedback rate of SZ series elevator assembly", and "improving the first processing qualification rate of gear rings", won the first prize.
The brake housing serves asTractorThe machining accuracy of the core components of the braking system directly determines the overall braking safety performance and driving reliability of the machine. The elite QC team of Da Tuo Company's braking system is rooted in the production line, focusing on on-site production pain points to carry out quality research and development. Through a solid investigation of the current situation, the group found that the size deviation of the locking hole spacing of "340 ± 0.02mm" is the main obstacle to improving the qualification rate of brake housing processing. Around this key issue, the team members fully utilized QC tools and conducted a full process root cause analysis from multiple dimensions such as human, machine, material, method, and measurement using a tree diagram. They systematically investigated the influencing factors, studied implementation control measures, and ultimately solidified a set of "precision dimensional accuracy control" combination solutions.
After the implementation of the plan, the qualified rate of brake housing processing steadily increased from 98.5% to 99.15%. The improvement of quality indicators has effectively ensured the high horsepower tractorproduction lineOrderly delivery, further consolidating“The East Is Red”The foundation of product quality has maintained the brand reputation in the market.
The Central Enterprise QC Group Achievement Presentation Competition is an important platform for mass quality improvement in the field of central enterprises. Next, China Yituo will continue to promote the experience of QC group activities, encourage more frontline teams to engage in quality improvement and technological innovation, and empower enterprises with high-quality development through small innovations and creations.
