Patent AT-E401183-T1: [Translated] METHOD FOR PRODUCING MOLDED PARTS BY GAS-ASSISTED INJECTION MOLDING

Pressurized gas passes through a control valve (2) to the molding tool (3) and is introduced through a nozzle (6) into the molded component (4). Before reaching the tool (3), a cooling medium (8) is injected through a transfer valve (7). The cooling medium can be water, liquid or gaseous nitrogen, or liquid or gaseous carbon dioxide. An independent claim is also included for the corresponding equipment, incorporating controls to obtain optimum cooling of the component.
