The c - m group is the premier company in the world developing and manufacturing alloys and waxes for the investment casting industry 美國c - m集團公司是世界上開發并制造用于精密鑄造工業的合金及蠟料最前沿的公司。
The material cause of their subordinates in january 2003 created a total area of 100 , 000 square metres , is dedicated to apply to the aluminum alloy die - casting and forging ahead in the industrial production sector 其下屬的材料事業部于2003年1月創立，總占地面積為10萬平方米,是專門從事適用于壓鑄和鑄造工業的鋁合金錠的生產部門。
Rapid prototyping technology changed the traditional pattern of product design , which could offer product sample for the designer , reduced design cycle and quicken the schedule of new product design , and it gave the decision - makers visual feeling . ; rp technology provided kinds of molds including resin - boncled mold laminate mold , investment mold and lost foam casting mold and so on for sand casting investment casting and cavityless casting , it could also use direct shell production casting to make pattern dies metal dies die - casting dies injection dies directly , and it could even produce casting products in small scales . the applications of fdm technology in plaster precision casting and the rapid casting technology based on sls technology were introduced , the organic combination between rapid prototyping tecnnology and foundry process , which initiated a new period of rapid manufacturing metal parts , by using advanced new technology alternated traditional foundry industry to make it looked brand - new , thus , the competition of foundry industry would be improved ; rapid prototyping technology offered a rapid economical feasible technical method , common processes of using rapid prototyping technology to produce dies were discussed , in the paper it explored that . the problem of combining rapid prototyping technology with electric arc metal - spraying technology to make metal dies and technics in dies manufacturing of combining rapid prototyping technology with precision casting , rapid tooling based on rapid prototyping , integrated advanced new technology and tradition technology of rapid prototyping manufacture , each superiority were exerted , rapid prototyping technology had been an efficiency measure to rapid update products and develop new product , and to middle - 快速成型技術改變了傳統的產品開發模式，可以為設計者提供產品樣件，縮短設計周期，加快新產品的開發進度，為決策者提供直觀性；快速成型技術迅速提供砂型鑄造、熔模鑄造、實型鑄造用的各種模樣，包括樹脂模、層壓模、熔模和消失模等，還可采用直接制殼鑄造法直接制造熔模鑄造用的壓型、金屬型、壓鑄型、注塑模，甚至直接制造小批量鑄件，介紹了熔積成型技術在石膏型精密鑄造上的應用和基于選擇性激光燒結技術的快速鑄造技術，快速成型技術與鑄造工藝的有機結合，開創了快速制造金屬零件的新階段，對用高新技術改造傳統的鑄造工業，使其面貌煥然一新，增強鑄造行業的競爭能力；快速成型技術為母模的制造提供了一條快速、經濟、可行的技術途徑，討論了利用快速成型技術制造模具的一般工藝方法，探討了將快速成型技術與金屬電弧噴鍍技術結合起來快速制造金屬模具問題，以及快速成型技術與精密鑄造技術相結合的模具制造工藝，基于快速成型制造的快速模具技術，集成了快速成型制造高新技術和傳統技術，發揮各自優勢，已成為產品快速更新換代和新產品開發及中、小批量生產的有效手段之一。
Abstract : after describing the important tasks of the foundries in various countries at the joint of centuries , the present technological situation of the metal casting industry was analyzed . it was suggested that to apply information technique to foundry production is a key measure for foundries to survive and develop in the competition 文摘:在闡述了世紀之交各國鑄造廠的主要任務之后，分析了金屬鑄造工業的技術現狀，提出將信息技術應用到鑄造生產中是鑄造廠使自己能在競爭中生存和發展的關鍵措施之一。
