You are rotomolding a large children's toy with a very complicated shape and you have trouble getting good part definition and complete molding. You have a choice of resins having two melt indices. One is 30 and the other is 2 . Which would you choose and why?
What will be an ideal response?
The 30 because the higher melt index indicates the material's ability to flow, this increase in flow will allow for better part definition. Processing time will also be shorter by using the 30 rather than the 2.
