Discuss three ways to alleviate the sticking of a part to the mold.

What will be an ideal response?

Question 2

What constraints are necessary for biaxial rotation to evenly coat the mold in a rotational molding process?

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.
