Answer to Question 1

Inserts allow a single base to be used for multiple parts.
Inserts can be changed and modified easily should they be damaged.

Answer to Question 2

The extrusion of the parison for a very large part will often take a considerable amount of time. During this time the parison may begin to sag under its own weight. It could also begin to cool and therefore become more difficult to form.
