我厂广大职工发扬敢于创新的革命精神,在上海压铸机械制造厂等单位的协助下,于一九七二年四月完成了无箱射砂挤压造型自动线的安装工作,并正式投入了生产,为改变铸造行业的落后面貌、改善劳动条件,保护工人身体健康,奠定了良好的基础。 该线可实现小件湿模自动造型,是由射砂挤 The majority of employees in our factory developed the revolutionary spirit of daring to innovate. With the assistance of Shanghai Die Casting Machinery Manufacturing Plant and other units, in April 1972, we completed the installation of automatic injection molding without sandbox shot molding and officially put into production. It laid a good foundation for changing the backwardness of the foundry industry, improving working conditions and protecting the health of workers. This line can realize the automatic modeling of small wet molds, which are squeezed by shooting sand.
