An injection molding system includes a first unit that has a first injection molding machine configured to inject a first molding material into a first cavity partitioned by a first fixed mold and a movable mold, a second unit that includes a second injection molding machine configured to inject a second molding material into a second cavity partitioned by a second fixed mold and the movable mold, and a movement mechanism configured to, after the first molding material is injected into the first cavity, move the movable mold filled with the first molding material from the first injection molding machine to the second injection molding machine.

Forming a casing of an information handling system using dual area bi-injection, the method including injecting a first material into a mold: i) at first locations of the mold to form a first portion of a casing, and ii) at second locations of the mold to form a second portion of the casing; and injecting a second material into the mold at third locations of the mold to form a third portion of the casing; wherein injection of the first material and the second material into the mold is done concurrently, wherein injection of the first and the second material into the mold forms a first bonding interface and a second bonding interface between the first material and the second material such that the second material is excluded from ingression to the first portion and the second portion of the casing.

An injection molding machine includes an injection device including at least first and second injection units, and one mold clamping device. A molding material is injected into a first cavity space by the first injection unit, and a molding material is injected into a second cavity space by the second injection unit. The injection molding machine further includes a control device controlling the injection device and the mold clamping device, and a storage device storing a set time in advance. The control device starts injection of the second injection unit after elapse of the set time from a predetermined time point. The predetermined time point is a time point at which the first injection unit starts injection or an earlier time point. The set time is a delay time for delaying start of injection of the second injection unit from start of injection of the first injection unit.

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.

In an injection apparatus, a movable unit includes a ball screw including a moving block and a screw shaft. The moving block moves in a predetermined direction and is joined to an injection plunger. The screw shaft rotates to move the moving block. The screw shaft and the injection plunger are disposed side by side in a direction orthogonal to the predetermined direction. A fixing unit includes a first portion for holding a rear end part of the screw shaft, a second portion for holding a front end part of the screw shaft, and a third portion for holding the injection cylinder. The moving block is provided between the first portion and the second portion. The third portion is provided to be pressed by the injection cylinder when the injection plunger presses the resin.
