The Process The production process: Homework - continued 1. Extrudes the polypropylene liner, cools and coils it. 2. Uncoils the liner, braids wire around it and recoils it. 3. Uncoils the wire coasted liner, extrudes the coating onto it and cuts is to finished length. The Factor Listing The probability of conducting a successful experiment was increased by obtaining input from customers, production personnel, quality personnel and production engineers to list the factors that could contribute to post extrusion shrinkage. A large number of potential factors was then narrowed to 15 by a consensus process.

E V Homework - continued 1. Complete the response table and determine the strong effects. 2. Draw response graphs for the strong effects, and determine the optimal condition. 3. What is the optimal combination of factor levels? Compare this with the response at the existing condition, by calculating the response at the existing condition for strong effects. Where, = Ho response at the optimal condition = He response at the existing condition
