我厂以铸造生产为主,机械加工能力十分薄弱,随着我厂生产的不断发展,这一矛盾更为突出。在这种情况下,我厂广大革命职工,遵照伟大领袖毛主席关于“世间一切事物中,人是第一个可宝贵的,在共产党领导下,只要有了人,什么人间奇迹也可以造出来”的教导,发扬敢想敢干的革命精神,仅用二十几天的时间,成功地试制了熔模铸造铜质螺纹零件。从而减少了生产中切削加工总量30％,提高了劳动生产率,还为国家节省了大量的有色金属材料。从71年6月,输油泵的M33×1.6自动回流窥视孔压帽、1＂出口管接头及螺母、放油塞等十几种零件,已成功地采用熔模铸造生产,月产量达几千件。一般熔模铸出的件,经清理后即可直接应用。
I plant mainly to casting production, machining capacity is very weak, with the continuous development of our plant production, this contradiction is even more prominent. Under such circumstances, the vast majority of our revolutionary workers and workers and the great leader Chairman Mao’s statement on “All things in the world are the first to be of precious value. Under the leadership of the Communist Party, as long as there are people, what miracles can be created ”Teaching, carry forward the spirit of daring to dare to revolution, just twenty days, successfully trial-produced investment casting copper threaded parts. Thus reducing the production of 30% of the total cutting, raising labor productivity, but also for the country to save a lot of non-ferrous metal materials. From June 71, the M33 × 1.6 automatic reflow peephole pressure cap, 1 "outlet pipe joint and nut, oil drain plug and other parts of the oil pump have been successfully used in investment casting production, the monthly output of thousands Pieces. Castings generally cast, after cleaning can be applied directly.
