我厂铸造车间原来生产金属型铸件时,只有一台自制的简易手动浇注机。该机适用范围不广,工人操作时劳动强度大,不能满足生产发展的需要。为此,我们在吸取兄弟厂经验的基础上改进设计,成功地制造了一台三吨液压金属型造型机,推动了我厂金属型铸造生产的发展。 Casting plant in our factory originally produced metal castings, only a handmade simple casting machine. The machine is not widely used, the labor intensity of workers operating large, can not meet the needs of production and development. To this end, we draw on the experience of brothers plant on the basis of improving the design, the successful manufacture of a three-ton hydraulic metal molding machine, and promote the development of our metal casting production.
