Areas such as mounting points, long, thin cores or reinforcement webs in injection-moulded products are not always accessible with standard cooling water channels. Temperatures often remain too high in these zones due to clogging deposits in runners. As a result, these “hot spots” are barely cooled and require longer times to reach the desired temperature.
Moreover, small runner diameters as well as long distances between cooling channels and moulding surfaces lead to high pressure losses. The upshot is removal problems, surface defects, warping and longer cooling times.
We have developed a range of sophisticated temperature control solutions to access these areas and ensure uniform, accelerated cooling. We also support dynamic injection moulding by using carbon dioxide for both the cooling and heating cycle.
BOC provides PLASTINUMTM TEMP to increase the efficiency of dynamic injection moulding using carbon dioxide as a heat carrier and for spot cooling.
