模具技术是衡量一个国家制造工艺水平的重要标志之一。国际模具协会主席R.Sander说:“模具工业是金属加工业的帝王”,可见模具在机器制造业中的重要地位了。先进工业国的锻模费用占锻件费用的10～15%,我国中小工厂的锻模费用可达锻件费用的30%,有的竟达50%。这说明模具不但对锻件费用有举足轻重的影响,而且潜力很大,故国内外均花很大力量研究模具。 Mold technology is a measure of the level of manufacturing technology in one of the important signs. R.Sander, chairman of the International Mold Association, said: “The mold industry is the king of the metalworking industry.” This shows the importance of molds in machine building. Advanced industrial countries forging costs accounted for 10 to 15% of the cost of forging, small and medium-sized factory forging costs up to 30% of the cost of forgings, and some as much as 50%. This shows that the mold not only forging costs have a decisive influence, but also great potential, so both at home and abroad have spent a great deal of research mold.
