Adaptive system for electrically driven thermoregulation of moulds for injection moulding

One of the basic problems in the development and production process of moulds for injection moulding is the control of temperature conditions in the mould. Precise study of thermodynamic processes in moulds showed, that heat exchange can be manipulated by thermoelectrical means. Such system upgrades conventional cooling systems within the mould or can be a stand alone application for heat manipulation within it. In the paper, the authors will present results of the research project, which was carried out in three phases and its results are patented in A686\2006 patent. The testing stage, the prototype stage and the industrialization phase will be presented. The main results of the project were total and rapid on-line thermoregulation of the mould over the cycle time and overall influence on quality of plastic product with emphasis on deformation control. Presented application can present a milestone in the field of mould temperature and product quality control during the injection moulding process.
