摘　　要：粉末冶金的模具技术是生产和发展粉末冶金机械零件的关键技术之一,模具寿命的高低不仅影响产品质量,还影响生产效率和生产成本。为了尽可能的延长模具的使用寿命,保证产品质量,提高生产效率,本文分别从改进热处理工艺、表面处理两个方面来介绍多种可以延长模具使用寿命的方法。在具体的模具加工过程中,可以根据设备条件、模具原材料种类、模具的工作环境和精度要求来选择具体的延长寿命的方法。The technology of making toolings is the key technology to the production and development of powder metallurgy machinery parts. The toolings dimension accuracy is crucial to the level of production quality,and its life directly relates to the production efficiency and costs. This paper introduces a variety of methods that can extend the life of toolings to a maximum level,ensuring production quality and improving efficiency. The methods can be divided into two main categories,i. e.,innovating heat treatment process and surface treatment. In one specific tooling processing,a life-prolonging method can be selected according to the equipment conditions,types of raw die materials,working environment,and accuracy requirements.
