An injection mold structure includes a main portion, a core plate, multiple runners, a removable metal plate, a top portion, a resin mold. The core plate is in physical communication with and located within the main portion. The removable metal plate is in physical communication with the runners and the core plate. The runners are located in between the core plate and the removable metal plate. The top portion includes a cavity to receive a carbon fiber plate.

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.

Dual area bi-injection molding

In one embodiment, a rigid plate of a display for an information handling system includes: a main rigid portion having a first plate thickness; and a recessed rigid portion having a second plate thickness less than the first plate thickness, the recessed rigid portion including one or more interlock holes disposed proximate to an edge of the recessed rigid portion, the one or more interlock holes configured to couple the rigid plate to a display chassis of the display via an interlock portion.
