英国贸易工业部在七十年代,调查英国工业状况时,发现工业中需要现代化的主要是机械加工行业。其中一个重要的方面是模具制造业。需要开展研究的有模具光洁度、高温磨损、裂纹、变形及润滑等方面的问题。 美国自五十年代中期开始重视铸造模具的应用,应用范围遍及压铸模、注塑模、锻模及镶块。铸造模具在英国受到较大限制,在锻模上应用甚少。其它较早开展铸造模具
In the seventies, when Britain’s Ministry of Trade and Industry investigated the state of British industry, it was found that the major industries that needed modernization were the mechanical processing industries. One of the most important aspects is the mold manufacturing industry. Need to carry out research are mold finish, high temperature wear, cracks, deformation and lubrication and other issues. Since the mid-1950s, the United States has placed great emphasis on the application of foundry molds. The applications range from die-casting molds, injection molds, forging dies and inserts. Casting mold in the United Kingdom by the greater restrictions on the use of forging on the few. Other earlier casting mold
