Abstract
Hot-runner system (100) for use with molding system. Hot-runner system (100) having: heater (102) to generate heat responsive to receiving power. Heat-sourcing component (104) to receive heat from the heater (102) so that the heat that is generated by the heater (102) is transferred, at least in part, from heater (102) to heat-sourcing component (104). Heat-sourcing component (104) becomes heated to an operating temperature. Heat-receiving component (106) being at least partially spaced from the heat-sourcing component (104). The operating temperature of the heat-receiving component (106) being cooler than operating temperature of the heat-sourcing component (104). Non-structurally supportive heat insulator (108) has thermal conductivity being lower than thermal conductivity of air during operation of the hot-runner system (100). Whereby, in use, non-structurally supportive heat insulator (108): (i) reduces heat transmission from heat-sourcing component (104) to heat-receiving component (106), and (ii) permits reduction of power consumption of heater (102).
