The processing temperature is the key that can decides the product quality in the plastic production process. The paper discusses the concrete application of Delta temperature controller in the plastic processing production procedure, it can guarantee that the production temperature of raw material can be accurately controlled in the complex production environment. And therefore it avoided the phenomena that makes waster ratio to be higher caused by overhigh or lower temperature.
