The size of the plastic injection mold base is determined primarily by the area required to accommodate the designed cavity layout.A primary issue, however,is the potential for conflict between the placements of the cavities and other plastic injection mold components(such as leader pins,guide bushings,and others).Furthermore,there is the potential for conflict between cavity support systems(such as cooling lines,ejector pins,support pillars,etc.)and other plastic injection mold components(such as leader pins,guide bushings,and others.)Due to these conflicts, injection mold bases are often sized larger than what would first be considered.
