摘　　要：在"以塑代钢"、"以塑代木"的必要趋势下,注塑模具的发展就更显得重要,尤其是最能代表生产力的长寿命、高精度的模具。文中简要介绍了稀土热扩渗技术在注塑模具表面处理中的运用,并将其与未添加稀土渗剂的传统热扩渗技术相比较,全面有效的说明了稀土热扩渗的优势,有效催渗,并能增加渗层厚度与硬度,提高注塑模具的使用寿命与精度。In pace of the necessary trend--＂steel replaced by plastic＂and＂wood replaced by plastic＂, the development of mould industry is particularly important. Especially the most representative productive forces is the mould of long life, high precision. The article briefly introduces the rare earth thermal diffusion technology in plastic in- jection mould cavity surface treatment. It compares to the traditional thermal diffu- sion technology without rare earth, comprehensive shows the advantages of rare earth thermal diffusion technology, effective catalyze permeability, increases the diffusion layer thickness and hardness, improves the service life and precision of plastic injec- tion mould.
