Answer to Question 1

To normalize the stresses that are induced by the molding process

Answer to Question 2

The submarine gate is used when the part is to be removed automatically from the runner system. The edge is the least expensive gate type. The ring gate is for parts that are cylindrical and it allows flows in the part that are non-turbulent. It may also allow knit lines to be eliminated.
