Abstract: The reliable equipment preventive maintenance level and excellent product quality assurance ability are important for manufacturing enterprises. Most existing studies focus on the relationship between management and business performance. Based on the review of quality control and maintenance management, the influence of maintenance management model on process quality control is studied by taking continuous production in manufacturing industry in this paper. The reflection of the relationships between different factors and the change of relationship is put forward by using research hypotheses. The relationship and hypothetical framework are described and analyzed by structural equation modeling (SEM). Studies show that basic maintenance management activities have indirect effects on maintenance performance. Total productive maintenance (TPM) and reliability centered maintenance (RCM) have strong direct effect on the maintenance performance with path coefficients being 0.346, 0.717. Equipment maintenance performances have effect on the performance of process quality control with path coefficients being 0.922. The result shows that manufacturing enterprises should optimize the equipment preventive maintenance system for improving product quality.
