Blow Molding vs  ABS Injection Molding  Comparison Both these processes do not produce same types of shapes and are relatively different when it comes to the method and material used, production speed, production cost, sizes and designs. Blow Molding tends to be faster and less expensive for high volumes of hollow shapes.
