Chongqing Chi has successfully deployed MES to realize lean management of manufacturing sites

Chongqing Chiyu Auto Parts Co., Ltd. (hereinafter referred to as Chongqing Chiyu) and Beijing Axter Technology Co., Ltd. (hereinafter referred to as Extech) have successfully implemented the MES manufacturing execution system, marking a significant step in Chongqing Chiyu's lean management of the production process. This collaboration has enabled faster transfer of process information to the shop floor, significantly boosting the efficiency of the manufacturing department. As a well-known private enterprise in the auto parts industry, Chongqing Chiyu has a strong technical team and numerous patents. It has been recognized as one of the top ten suppliers by Changan Group, Hafei Group, and Changhe Group. As a leading manufacturer in Chongqing, Chongqing Chiyu has continuously optimized its industrial structure to enhance market competitiveness. For years, the company has focused on product R&D, production management, quality control, and sales as key drivers of growth. With evolving market demands, it has continually refined its business processes to accelerate production and improve quality management. To support these efforts, the company has adopted ERP and other digital tools to streamline internal operations. However, for managing BOMs, planning, scheduling, inventory, materials, and personnel at the production level, an integrated information system was essential. After evaluating various providers globally, Chongqing Chiyu chose Extech’s “ExtechMES Lean Manufacturing Planning Execution System” as its core platform for deploying the MES solution. The management of Chongqing Chiyu placed high importance on this MES project, forming a dedicated project team to work closely with Extech’s technicians. Through in-depth discussions, they analyzed the needs and challenges of different departments and tailored Extech’s MES solution to fit Chongqing Chiyu’s overall business model. The system was eventually deployed across multiple departments, including stamping, welding, over-welding, door assembly, stabilizer bar, metalworking, assembly, warehouse, technical center, and human resources. The goal was to streamline data flow between departments, speed up file processing, and establish collaborative data management with ERP. After the joint efforts of both teams, the Chongqing MES system was successfully launched within the planned timeline. Its benefits are clear: the technical center can now maintain and share process resources across departments, greatly reducing information errors. Production plans for daily, weekly, monthly, and quarterly cycles are quickly deployed and monitored accurately through MES. These data are visually presented to production managers and frontline operators, allowing them to track tasks, report labor, access process documents, and check working hours performance. Combined with electronic signage, the system supports paperless operations, reduces manual orders, and streamlines data collection. The integration of MES with ERP also reduces the workload for warehouse staff and improves the accuracy and real-time nature of inventory records. Quality management is a crucial part of Chongqing Chiyu’s operations. MES has established a complete and effective quality inspection process, using patrol inspections and quality alarms to help identify production issues early. Production performance data is vital for motivating employees, and MES enables frontline workers to track their progress, performance, and returns while making it easier for managers to review, calculate costs, and manage production efficiently. The General Manager of Chongqing Chiyu stated that the implementation of Extech’s MES system has brought tangible value to the company’s digital transformation. In the workshop, production tasks are clearly planned, and intuitive data is available to managers, enhancing their awareness and control over production rhythms. Inventory, production information, data statistics, and personnel performance are all visible at a glance, contributing to more efficient decision-making. The successful application of MES has helped Chongqing Chiyu achieve its goals in lean production management at the factory level. **About Extech MES Lean Manufacturing Execution Planning System** ExtechMES optimizes all production activities from order placement to product completion.

Pneumatic Flow Control Valve

Pneumatic Flow Control Valve is used to reduce the rate of flow in a section of a pneumatic circuit, resulting in a slower actuator speed. Unlike a Needle Valve, a Flow Control Valve regulates air flow in only one direction, allowing free flow in the opposite direction.
