    • A multi element moving vacuum chamber (MEMVC) for rotational casting includes a mold (6) having a predefined shape and an axis of rotation, and a box (8) containing casting material (9). The MEMVC further includes a first vacuum element (11) mounted to an outer mold surface and a second vacuum element (12) mounted to an outer box surface. The mold (6) and the box (8) are detachably engageable with each other to define an engaged configuration in which air present in an enclosed area defined by the outer mold surface and an inner surface of the first vacuum element, by an inner mold surface and an inner box surface, and by the outer box surface and an inner surface of the second vacuum element (2), is removed to create a vacuum. Alternatively, the mold and/or box may be constructed with vacuum loading capability, thereby eliminating the need for the first and/or the second vacuum elements.
    • 用于旋转铸造的多元件移动真空室(MEMVC)包括具有预定形状和旋转轴线的模具(6)和包含铸造材料(9)的盒子(8)。 MEMVC还包括安装到外模表面的第一真空元件(11)和安装到外盒表面的第二真空元件(12)。 模具(6)和箱体(8)能够彼此可拆卸地接合,以限定啮合构型,其中存在于由外模具表面和第一真空元件的内表面限定的封闭区域中的空气通过内模 表面和内盒表面,以及外盒表面和第二真空元件(2)的内表面被去除以产生真空。 或者,模具和/或盒可以被构造成具有真空负载能力,从而消除对第一和/或第二真空元件的需要。
