【摘要】 本文概述了拉挤模具对成型工艺的关键性意义。电镀模具的制造工艺相对较为成熟，应用已相当广泛；不带硬铬镀层的拉挤模具是近几年出现的，也得到较多的应用，但还存在一系列根本性技术问题，有待深入解决。电火花钱切割应是模具型腔加工首选的加工方案，型腔表面的研磨和高精度抛光是非常重要的。模具胚料的锻造、退火（正火）及调质工艺的正确与否，是影响模具变形的最基本因素。更多还原

【Abstract】 Ths paper briefly discusses the significance of pultrusion die in pultrusion process. Themanufacturing process for die electroplating is relatively mature and has been widely used, the die without hardchromic layer emerged only in recent years and has found more applications, but it has a series of technicalproblems to be sohved further. Sparking line cutting of cavity of die is the first machining plan to be chosen, thelapping and high accurate polidshing of die cavity is very important, the forging, annealing and quenching processesare the basic factors effecting the die deformation.更多还原
