On-line detection of fouling in a water circulating temperature controller (WCTC) used in injection moulding: Part 2: Application

The technique presented in this paper aims at alerting the user that fouling has modified the capabilities of a WCTC, pointing out the affected component so that predictive maintenance can be carried out, reducing the exploitation costs of the WCTC. The technique presented in the first part (principles) is applied. In a first step, the characteristic vector of the WCTC is determined. In a second step, experimental results that validate the technique are presented.
