The quality of plastic injection-molded components depends essentially on tooling design (e.g. heating and cooling system).
Only with optimum mold temperatures can a molder guarantee high dimensional stability and surface quality of finished components. Especially with multiple-cavity molds, temperature uniformity is vital for achieving identical tolerances throughout the moldings in the various cavities.
Thermographic systems make a major contribution to obtaining optimum tool temperature. For infrared measurements it is important to know, however, that these molds have highly reflective surfaces. This can be overcome either by blackening the molds, or by means of an "indirect" observation of the molds.
With this indirect measurement, temperature distribution is monitored on the injection moldings (having a temperature of 60 to 110 °C), after completion of the molding operation, and checked for thermal anomalies.
This procedure is ideally suited for drawing conclusions about the temperature distribution in the mold, allowing molders to decide about possible improvements if the need arises.
