六十年代以来,随着铝建筑型材的广泛应用,中小型挤压机得到了迅速发展。目前美国、日本、西德和法国,是当今世界上铝建筑型材生产与应用较发达的国家,也是铝型材挤压机制造较多和设计制造水平较高的国家。主要的制造厂家有:美国的萨顿(SUTTON)公司,西德的施勒曼—西马克(SMS)公司,法国的克莱西姆(CLECIM)公司和日本的宇部兴产(UBE)公司等。近年来,我国的铝建筑型材及其制品的生产,以及铝建筑型材挤压机的研制,刚刚起步,其生产水平和装备水平与国外相比,均存在较大差距。目前,我国已从国外引进
Since the 1960s, with the extensive use of aluminum building profiles, small and medium-sized extruders have been rapidly developed. At present, the United States, Japan, West Germany and France are the countries with advanced production and application of aluminum profile in the world. They are also the countries with more aluminum extrusion machines and higher design and manufacturing. Major manufacturers include Sutton in the United States, Schleman SMS in West Germany, CLECIM in France and UBE in Japan . In recent years, China’s aluminum building profiles and their products, as well as the aluminum profile extrusion molding company has just started, its production level and equipment level compared with foreign countries, there is a big gap. At present, our country has imported from abroad
