An injection molding device and related method includes a mold plate with at least one pocket having at least one discharge opening to discharge melted plastic from the pocket into at least one mold cavity interconnected to the pocket and a nozzle including a housing, which during operation is interconnected to the pocket. Per discharge opening a needle is arranged displaceable in an axial direction in the housing between a closed position and an open position. In the closed position the needle closes the thereto related discharge opening and is thereby preventing melted plastic from flowing from the pocket into the at least one mold cavity. In the open position, the needle releases the discharge opening such that melted plastic flows from the pocket into the at least one mold cavity. Furthermore, a melt channel is discharging into the pocket to supply melted plastic into the pocket.

An Injection molding apparatus injection molding apparatus (10a) comprising: one or more first downstream channels (166, 166a, 166b) and associated first gates (34, 34a, 34b) that deliver injection fluid (18) to a first cavity (300a) of a mold system (302, 303) and to one or more second downstream channels (168, 168a, 168b) and associated second gates (32, 32a, 32b) that deliver injection fluid to a second cavity (300b) of the mold system (302, 303), the mold system being clamped together under a selected force, the apparatus including a first upstream valve (118) that enables and disables flow of the injection fluid to the first gates (34, 34a, 34b) and a second upstream valve (108) that enables and disables flow of the injection fluid to the one or more second gates (32, 32a, 32b), the apparatus including a control system (20) adapted to open or enable flow of the injection fluid (18) to the one or more first gates (34, 34a, 34b) at a first selected time and to further instruct the second upstream valve (108) to open or enable flow of the injection fluid (18) to the one or more second gates (32, 32a, 32b) at a second selected time that is delayed relative to the first selected time during the course of an injection cycle.

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.
