    In the extrusion line, it is the die that takes the plastic melt from the extruder and shapes it into the finished or semi-finished product. The product can be tubes, pipes, rods, profiles, coated wires, cables, filaments, film, or sheet. Whatever the product may be, the purpose of the die is to shape the plastic melt into a desired form.

The major problem is to design a feed system (i.e., manifold) that will distribute the melt uniformly to the shaping portion of the die (see Fig. 25 for definition of parts of a die). In the event this is not possible, then it must be possible to adjust the die lips in such a way that the fluid will leave the die with a uniform thickness.
