遵照毛主席关于“打破洋框框,走自己工业发展道路”的伟大教导,我们依靠群众,反复实践,大胆对仿苏活塞式气动压蜡机进行改造,直接用压缩空气压蜡获得成功。实践表明:这种无活塞气动压蜡装置,结构简单,制造容易,上马快,投资少,工作可靠,特别适用于压型大小悬殊、多品种少批量生产的精铸车间。 Following Chairman Mao’s great teaching on “breaking the framework of the world and following our own path of industrial development”, we relied on the masses and repeated our efforts to reform the imitation-SU piston-type pneumatic waxing machine and obtain the success of direct compression with compressed air wax. Practice shows that: This non-piston pneumatic pressure wax device has the advantages of simple structure, easy manufacture, quick start-up, less investment, and reliable work, and is particularly suitable for a precision casting workshop with a large pressing type and a small volume.
