Abstract: An injection-molding system includes an extruding system configured to produce a mixture; a discharging channel communicable with the extruding system and including an outlet configured to discharge the mixture; and molding devices configured to receive the mixture. Each of the molding devices includes a hollow space, and a feeding port communicable with the hollow space and engageable with the outlet. An injection-molding method includes providing an extruding system configured to produce a mixture, a discharging channel including an outlet, and first and second molding devices; engaging the outlet with the first molding device; injecting the mixture into the first molding device; disengaging the outlet from the first molding device; moving the discharging channel away from the first molding device and toward the second molding device; engaging the outlet with the second molding device; injecting the mixture into the second molding device; and disengaging the outlet from the second molding device.
