发明名称 Enhanced gravity casting
摘要 An apparatus and method for enhanced gravity casting wherein a portion of the mold is maintained in pressure contact with molten metal as it solidifies to allow the mold surface to follow the contraction of the solidifying metal. A further feature of the invention is the use of an air clearance between mold parts that is sufficient to allow air to escape but insufficient to allow molten metal to flow therepast.
