Answer to Question 1

The parison of the part must be able to be formed without excessive deformation under the weight of the parison itself and must be formed within the time that the resin is still hot. This is determined by the melt strength of the resin, the speed of formation of the parison, and the temperature. Also important are the wall thickness and the blow-up ratio.

Answer to Question 2

The thinnest sections will occur in the areas where the material must move the farthest to fill the mold. The most common location for these thin areas is therefore the corners.
