Answer to Question 1

Use mold release. Use cold air to cause the part to shrink away from the mold and to lift the part away from the mold. Use dry ice to shrink the part. Change the molding conditions to reduce degradation.

Answer to Question 2

Biaxial rotation must have both axes rotating simultaneously. The frequency of rotation should be different for each axis, and the rotational frequencies should not be even multiples of each other.
