Describe sliding/compression blow molding and indicate its advantage
What will be an ideal response?
Sliding/compression blow molding allows sections to be created on blow molded parts that are undercut or otherwise shaped in some method other than by just blowing outward against the mold cavity. These special sections are created by blowing the parison into a recess in the wall of the mold cavity. The material in this recess is pinched during the molding process, thus compressing the material and giving it form. The pinching is usually done by sliding part of the mold against a fixed part of the mold. The finished part is removed by reversing the sliding and then opening the mold in the normal way for blow molding.
