The correct answer is:
(b) False
Explanation: The main purpose of squeeze casting is not to produce castings with high segregation but to produce castings with high density, fine microstructure, and low porosity. This process involves applying pressure to molten metal during the solidification phase, which helps reduce shrinkage and porosity, resulting in parts with improved mechanical properties.
Squeeze casting is especially useful for creating high-quality, defect-free castings, and it can be applied to produce both small and large castings. However, the goal is typically to reduce segregation and improve uniformity in the casting, not to promote it. Therefore, the statement is false.
