Answer to Question 1

Cryogenic flash removal simply means that the parts are frozen when the flash is removed. This freezing makes the plastic brittle and, because the flash is thin, increases the likelihood that the flash can be broken off the parts when they are tumbled together.

Answer to Question 2

The flash type closure system is much simpler than the positive and semipositive systems. Therefore, mold costs are lower. However, the part dimensions are less well defined and, of course, flash must always be removed from the parts.
