常见的低熔点合金材料有铋基合金、锌基合金、铅锡锑铜四元合金等,这些材料具有熔点低、强度高、流动性好、胀缩率小、与样件不粘连、无毒性等特性。近年来,我国的低熔点合金模具发展很快,但由于对这项新技术宣传不够,现用的铋锡合金模材料来源又受到限制,所以影响了推广工作的广泛开展。烟台机械工艺研究所在中国科学技术情报研究所协助下,并参考国外经验,对锌基低熔点合金模具的应用研究工作已获得成功,并投入了小批量生产。锌基低熔点合金模具除了具有一般低熔点合金材料的优点外,还具有材料资源充足、炼
Common low-melting alloy materials are bismuth-based alloys, zinc-based alloys, lead-tin antimony copper quaternary alloys, these materials have low melting point, high strength, good fluidity, shrinkage rate is small, non-adhesion with the sample, non-toxic Other features. In recent years, China’s low melting point alloy die developed rapidly, but due to the new technology is not enough publicity, the available sources of bismuth-tin alloy die material has been restricted, thus affecting the promotion of a wide range of work. With the help of China Institute of Science and Technology Information and the reference of foreign experience, Yantai Machinery Technology Research Institute has succeeded in applying and researching the application of zinc-based low-melting-point alloy molds and has put into small-batch production. Zinc-based low-melting-point alloy die in addition to the general advantages of low melting point alloy materials, but also has sufficient material resources, refining
