Answer to Question 1

The dividing line is where the heated resin is cooled. When the resin is cold, it will naturally separate from the hot, molten resin at the sprue bushing. The nozzle is heated and so the resin within the nozzle is hot. The mold is cooled and so the material inside the mold, all the way back to the sprue, is cold. The sprue bushing is the normal separation point.

Answer to Question 2

The shot size and the clamping pressure are the important measures of capacity of an injection molding machine. (1) The shot size is the amount of material that can be injected.

This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
