Abstract
Methods of casting improved scroll compressor components having high quality involute portions are provided. The casting method comprises gating molten metal through a patterned region of a core or mold defining the involute vanes. In certain aspects, during casting, molten metal passes through one or more gates that extend through a core in a central patterned region that forms the involute portion of the scroll component. In certain variations, the metal comprises a gray cast iron, so the cast part comprises an involute having a matrix of pearlite and Type A graphite that is substantially free of undercooling defects. Further, in certain variations, the involute portion is substantially free of Types B-E graphite. Thus, high-quality low-defect cast scroll components are formed having good machinability and superior fatigue strength.
