    • Some embodiments provide methods and systems for casting articles. One example of a method includes providing and positioning a thermal blanket within a mold cavity and then introducing a molten material into the mold cavity and into contact with the thermal blanket. The method allows the molten material to remain in a molten state during a dwell time that extends from the introduction of the molten material at least until the mold cavity is filled. In another example, a method of using a thermal blanket includes keeping a molten material in a molten state during a dwell time extending from first introduction of the molten material until pressurization. Systems including a variety of mold types, one or more thermal blankets, and in some cases preforms and/or inserts are also provided. Also described is a novel thermal blanket and method of manufacturing the same.
    • 一些实施例提供了用于铸造制品的方法和系统。 一种方法的一个实例包括提供并将热毯定位在模腔内,然后将熔融材料引入模腔并与热毯接触。 该方法允许熔融材料在从引入熔融材料延伸的停留时间期间保持在熔融状态,至少直到模腔被填充。 在另一个实例中,使用热毯的方法包括在熔融材料的第一次引入直到加压的停留时间内保持熔融材料处于熔融状态。 还提供了包括各种模具类型,一个或多个热毯,以及在某些情况下的预制件和/或插入件的系统。 还描述了一种新型热毯及其制造方法。
