Abstract: A prefabricated sprue assembly provides attachment to independently-produced investment casting molds to substantially reduce the need for pattern material. Installable connections between the prefabricated sprue assembly and the investment mold allow substantial reduction of scrap loss caused by errors in production of individual investment molds by culling defective molds before installation to the sprue assembly.
Abstract translation: 预制浇口组件提供附接到独立生产的熔模铸造模具，以大大减少对图案材料的需要。 预制浇道组件和投资模具之间的可安装连接允许在安装到浇道组件之前，通过剔除有缺陷的模具，大大减少由个别投资模具生产中的错误引起的废料损失。

Abstract: An investment casting method involves producing a casting shell by applying a hardenable refractory material to a sacrificial pattern. The casting shell having a plurality of phosphate bonds in the hardenable refractory material, which provide increased structural integrity during casting and improved frangibility during shell removal. The casting shell may also have a plurality of gaseous pockets suspended in the refractory material, which do not degrade the structural integrity during casting and provide improved frangibility during shell removal.
Abstract translation: 熔模铸造方法涉及通过将可硬化耐火材料应用于牺牲图案来生产铸造壳体。 铸造壳体在可硬化耐火材料中具有多个磷酸盐键，其在铸造过程中提供增加的结构完整性，并且在壳体去除期间提高了易碎性。 铸造壳体还可以具有悬挂在耐火材料中的多个气体袋，其在铸造过程中不降低结构完整性，并且在壳体移除期间提供改进的易碎性。
