Discuss why the compression zone of a nylon-type screw is so much shorter than the compression zone in a polyethylene-type screw

What will be an ideal response?


Nylon melts over a much narrower range than polyethylene. Since the purpose of the compression zone is to melt the polymer, the distance to do the melting need not be as long with the more easily melted nylon.
