我厂线路金具产品的生产长期以来使用震压式造型线组织生产。工人劳动强度大,工作环境恶劣,产品废品率高。随着线路金具产品需求量的增加,震压式造型生产线已不能适应其生产发展的需要。我厂在一九七九年自制了两台ZZ415垂直分型无箱挤压造型机并组成了一条简易生产线。经过近半年来对该线的调 The production of line fittings in our factory has been used for a long period of time in the production of shock pressure style lines. Workers have high labor intensity, bad working conditions, and high product rejection rates. With the increase in the demand for line hardware products, the shock pressure molding production line can no longer meet the needs of its production and development. In 1979, our factory produced two ZZ415 vertical sub-type extrusion molding machines and formed a simple production line. After nearly six months of adjustment to the line
