摘　　要：模压成形是粘结NdFeB磁体制造的最主要方法。分析了粘结NdFeB磁体的特点;在实验研究和大量生产实践的基础上,介绍了模具结构、压机结构和压制成形动作对磁体质量的重要影响;总结了控制粘结NdFeB磁体质量的关键技术。Mould pressing is the most important preparation method for bonded NdFeB magnets. Characteristics of bonded NdFeB magnets were analyzed. Based on experimental research and lots of production practices, the impor- tant effects of die structure, press structure and compacting actions on magnets quality were introduced. The key techniques for controlling the quality of bonded NdFeB magnets were also summarized.
