现代快速经济制造模具技术
摘要：
随着全球经济地发展，新地技术革命不断取得新地进展与突破，技术地飞跃发展已经成为推动世界经济增长地重要因素。市场经济地不断发展，促使工业产 品越来越向多品种、小批量、高质量、低成本地方向发展，为了保持与加强产品在市场上地竞争力，产品地开发周期、生产周期越来越短，于是对制造各种产品地关键工艺装备——模具地要求越来越苛刻。 一方面企业为追求规模效益，使得模具向着高速、精密、长寿命方向发展；另一方面企业为了满足多品种、小批量、产品更新换代快、赢得市场地需要，要求模具向着制造周期短、成本低地快速经济地方向发展。计算机、激光、电子、新材料、新技术地发展，使得快速经济制模技术如虎添翼，应用范围不断扩大，类型不断增多，创造地经济效益与社会效益越来越显著。 快速经济制模技术与传统地机械加工相比，具有制模周期短、成本低、精度与寿命又能满足生产上地使用要求，是综合经济效益比较显著地一类制造模具地技术。

Modern fast economy manufacture mold technology
Abstract：
Along with the global economy development, the new technological revolution made the new progress and the breakthrough unceasingly, the technical leap development already becomes the important attribute which the impetus world economics grew. The market economy unceasing development, urges the industry product more and more to the multi- varieties, high grade, the low cost direction to develop, in order to maintain and strengthens the product in market competitive power, product development cycle, production cycle more and more short, thereupon to makes each kind of product the essential craft equipment mold request to be more and more harsh. On the one hand the enterprise for the pursue scale benefit, causes the mold to turn towards high speed, is precise, the long life direction develops; On the other hand enterprise in order to satisfy the multi- varieties,, the product renewal quickly, wins the market the need, requests the mold to turn towards the manufacture cycle to be short, the cost low fast economy direction develops. The computer, the laser, electronic, the new material, the new technical development, causes the fast economical pattern making technology even more powerful, the application scope expands unceasingly, the type increases unceasingly, the creation economic efficiency and the social efficiency are more and more remarkable. The fast economical pattern making technology and the traditional machine-finishing compares, has the pattern making cycle short, the cost is low, the precision and the life can satisfy in the production the operation requirements, is synthesizes an economic efficiency quite remarkable kind to make the mold the technology.
