The extrusion control system is referred to as not only the operator/

machine interface and monitoring center, but also all of the individual

motors, drives, temperature controllers, and measurement devices required

to manage the extrusion process. A precise control (and monitoring)

of process variables provides the ability to produce a product with

repeatable accuracy, high productivity, and low waste. At the same time,

the accurate control and monitoring of the extrusion process are

extremely important in troubleshooting, and for documentation and quality

control purposes.
