意大利与西德、美国等国的技术交流比较频繁,因此,意大利在单件小批的中大件造型中,采用自硬砂混砂机造型的已相当普遍。但有的工厂考虑到经济性,仍将双轨移动式抛砂机作为主要的造型设备。本文就意大利生产的自硬砂混砂机(也称连续式混砂机)和抛砂机的结构、使用等情况作一简要介绍。 Italy and the West Germany, the United States and other countries more frequent technical exchanges, therefore, Italy in a single small batch of large and medium-sized shape, the use of self-hardening sand sand molding machine has become quite common. However, some factories take into account the economy, still dual-track mobile sand throwing machine as the main modeling equipment. This article makes a brief introduction on the structure, use and so on of self-hardened sand mixer (also called continuous sand mixer) and sand-throwing machine produced in Italy.
