前言投资数十亿巨款建成的高压造型工厂到处都存在着问题,然而这些问题并非采用高压造型后才出现的,早在70～71年以后新建的中压造型工厂中,绝大部分都是有问题的,并经常发生故障,只是由于现场技术人员的努力,采取多种应急的措施,费了好大的劲,才防止了故障的表面化。由于没有探明中压造型失败的真正原因就进入了高压造型,使得目前的高压 Preface There are problems in the high-pressure molding factories built with billions of dollars of money invested. However, these problems did not emerge after high-pressure molding. As early as 70 to 71 years later, most of the new medium-pressure molding factories were There are problems, and frequent failures, just because of the efforts of field technicians to take a variety of emergency measures, took a great effort to prevent the failure of the surface. Because there is no proven reason for the failure of medium-pressure shape into the high-pressure modeling, making the current high pressure
