摘　　要：介绍了盘状类、环状类熔模精铸件的工艺设计要点及注意事项,并就“多热节、多浇冒口”设计原则及围绕这个原则采取的一系列措施:浇口圈、环形模头以及如何提高该类铸件的工艺出品率展开讨论。这些实例均已用于批量生产。Key designing point and noted items on processing of plate and ring parts in investment casting have been described, and designing regularity of multi-hot spot and multi-risers as well as series of countermeasures based on the above regularity have been approached. Riser-ring, ring module as well as how to improve the yield rate of these investment castings were introduced.
