锌基合金模是快速制模技术之一,60年代世界上一些技术发达的国家如美国、日本、西德等国已在一定范围内较多地采用。一、锌基合金模的适用范围锌基合金模使用范围较广。锌铝合金超塑性模可用于热塑性塑料模及成形模。锌基合金模则适用于刀口模、成形模及热塑性塑料模。而低熔点合金模(锡铋合金)只能用于成形模。钢皮模与钢板模只能用于刀口模。二、锌基合金模的制造特点锌基合金是由约93％Zn、4％A1、3％
Zinc-based alloy mold is one of the rapid prototyping techniques. In 1960s, some developed countries in the world such as the United States, Japan, West Germany and other countries have adopted more in a certain range. First, the scope of application of zinc-based alloy die Zinc alloy die wider use. Zinc-aluminum alloy superplastic mold can be used for thermoplastic molds and forming molds. Zinc-based alloy die is suitable for knife-edge die, forming die and thermoplastic mold. The low melting point alloy die (tin bismuth alloy) can only be used for forming die. Steel mold and steel mold can only be used for knife-edge mold. Second, the zinc-based alloy mold manufacturing features Zinc-based alloy is about 93% Zn, 4% A1, 3%
