Direct Heatcon is an extremely efficient molding technology unique to Aoki that controls the temperature of the preform, an important aspect of plastic container molding, using only residual heat from the injection molding process.
Eliminating the need for a reheating step means that containers can be molded faster. Once the resin has reached the right temperature, container molding can be carried out after only a few shots of preform molding, thereby reducing the time required and enabling high-speed, energy-efficient container molding.
Using the residual heat from the preform molding process during stretch-blow molding totally eliminates preform re-heating expenses, and enables further savings in energy and space because preforms can be cooled in less time and chillers can be downsized. Direct Heatcon embodies Aoki's goal ever since its inception of molding containers with minimum expenditure of time and energy.
