Abstract: A mold-tool system (100), having a one-piece manifold assembly (102) is provided. The one-piece manifold assembly (102) has: a plurality of inlets (104); and a plurality of outlets (106) spaced apart from the plurality of inlets (104). A plurality of melt channels extend between the plurality of inlets and the plurality of outlets, and each melt channel extends between a single inlet and at least two outlets such that each inlet (104) is in fluid communication with at least two outlets (106).

Abstract: An injection-molding machine (100), including: an air-open circuit (110); an air-closed circuit (112); and a pressure-equalization circuit (118) connecting with the air-open circuit (110) and the air-closed circuit (112), the pressure-equalization circuit (118) being configured to: (i) operate in a by-pass operation mode, in which the air pressure between the air-open circuit (110) and the air-closed circuit (112) becomes equalized, at least in part, by recycling, at least in part, the air pressure between the air-open circuit (110) and the air-closed circuit (112); and (ii) operate in a pass-through operation mode, in which the air pressure in the air-open circuit (110) and the air-closed circuit (112) is independently controlled.
