七年前,在有关专业杂志上曾介绍过日本的现代化自动挤压厂,并叙述了日本现代化挤压厂的技术优势。但这几年来,西德挤压厂工艺和设备技术水平的提高仍然十分缓慢;如果说有提高,那也只是最近的事。我们把日本挤压厂与欧洲的或美国的进行一下对比,便可得出下述结论:每一条可比挤压线,在日本挤压厂内消耗一半的人工开支和废料,就可生产同样多或求更多的产品,而且制品表面质量至少水平相当或更好,壁厚也相当或更薄。
Seven years ago, Japan’s modern automatic extrusion plant was introduced in related professional magazines, and it described the technical advantages of Japan’s modern extrusion plant. In recent years, however, the technological level of the process and equipment at the West Germany extrusion plant has continued to improve. If there is any improvement, it is only a recent matter. When we compare the Japanese extrusion plant with that of Europe or the United States, we can conclude that each comparable extrusion line can consume as much as half of the labor costs and waste in a Japanese extrusion plant. Or find more products, and the surface quality of the products is at least equal to or better than that, and the wall thickness is also quite or thinner.
