我厂生产的自动显示调节仪表,以前大多数用金属或有色金属加工成型,既费钢材及有色金属,又浪费工时。通过无产阶级文化大革命,我厂职工开始向新工艺——少、无切削进军。大搞工程塑料和粉末冶金的应用。工程塑料的应用自1971年开始,当年有12种品种,共72000件零件。到1974年发展到151种,共821000件,塑料用量为7.2吨之多。
The automatic display and adjustment instrument produced by our factory was previously processed mostly with metal or non-ferrous metals, which cost both steel and non-ferrous metals and wastes man-hours. Through the proletarian cultural revolution, the workers of our factory began to move into new processes—less and no cutting. Engaged in engineering plastics and powder metallurgy applications. The application of engineering plastics began in 1971, when there were 12 species and a total of 72,000 parts. By 1974, it had grown to 151 species with a total of 821,000 pieces, and the amount of plastic used was 7.2 tons.
