Performance Measurement

How is feeder performance measured? This section introduces you to the metrics of repeatability, linearity, and stability as applied to feeder performance. Also discusses considerations of process timescales and how it impacts feeder performance and the quality of your end product.

The core task of every feeder in plastics application is to precisely, accurately and consistently control discharge rate to comply with the processor’s applicable process specifications and end-product quality standards.

But how exactly is feeder performance expressed, how can it be measured, and how can processors evaluate feeder performance in the plant? This section explains what goes into a complete expression of feeder performance, what it means, why it’s so important to your operation, and how to measure and monitor feeder performance.
