In order to build the firm awareness of “putting quality first and treating customers as supremacy” and accelerate the improvement of SUNWIN’s product quality, the Manufacturing Engineering Department has led the rectification and upgrade of refined interior and exterior decoration quality of the 9-series since last August. They have immediately sorted out 83 problems in refined interior and exterior decorations and organized the founding of a special working group headed by Guo Fuxiang, Director of the Manufacturing Engineering Department, and joined by the Technology Center, workshops of the Production Department, the Quality Assurance Department, and the Procurement Department.

    The project group adopted a weekly meeting system, analyzed the root cause of refinement problems in the form of PQCP, developed effective long-term and short-term measures, tracked the progress of problem rectification, and verified the rectification effectiveness until the problems reached the extent of 6/6 closure. With the continuous deepening of rectification, refinement problems had to meet higher and higher standards in order to pass. The project group rectified every problem detected, with attention to details and dead corners.

    In order to consolidate the rectification results and prevent recurrence of rectified problems, the project group also took three measures: First, sort out and send the Quality Control Form for Suppliers of Incoming Materials to SQE, SQA and the general assembly workshop, and require every role to exert stricter control over possible problems in incoming materials of suppliers identified in the control form, reject unqualified products, and refuse to install unqualified products; second, sort out and send the Control Form for Refinement Problems Related to Interior and Exterior Decoration Production of 9-Series to the general assembly workshop, and require it to exert stricter control and self-inspection over production and assembly problems identified in the control form to ensure that the delivered vehicles had appearance quality that met the requirements of customers; third, check the rectification of the ordered vehicles of all batches in the 9-series randomly, and inform the group members of any recurrence of rectified problems.

    With the active cooperation and efforts of different departments, 102 problems in refined interior and exterior decorations were successfully closed during more than 9 months. Steady improvements were made in the interior and exterior decorations of vehicles in the 9-series that were delivered, and the quality was also recognized and affirmed by group leaders and customers. The upgrading of refinement improvement further strengthens the refinement concept and lays the foundation for the future development and manufacture of vehicle models.
