Housing, method of producing the same, and electronic device including the same

An electronic device, comprising:

• a housing comprising:
• a first plate,
• a second plate facing in a direction opposite to that of the first plate, and
• a side member enclosing a space between the first plate and the second plate,
• and , the side member comprising a plurality of side surfaces;
• and
• at least one gate mark formed in each of the plurality of side surfaces of the side member,
• wherein the side member is injected as a resin comprising a rigidity reinforcement material comprising a predetermined content,
• wherein the at least one gate mark is disposed in a gate mark receiving groove formed lower than a corresponding side surface at each of the plurality of side surfaces, and
• wherein the gate mark receiving groove comprises an open portion formed in at least one of a first plate direction/or a second plate direction.

A housing formed by a method of solidifying a resin injected into an injection mold, the housing comprising:

• a front surface;
• a rear surface facing in a direction opposite to that of the front surface;
• a plurality of side surfaces enclosing a space between the front surface and the rear surface;
• and
• a gate mark receiving portion formed at each of the plurality of side surfaces, the gate mark receiving portion being configured to receive at least one gate mark according to a separation of the injection mold,
• wherein the gate mark receiving portion is formed by a processing portion disposed at a corresponding position inside a cavity of the injection mold,
• wherein the processing portion comprises a protrusion disposed inside the cavity of the iniection mold and comprising a side gate, and
• wherein the gate mark receiving portion comprises a gate mark receiving groove formed to comprise the at least one gate mark by the protrusion at a corresponding position of the side surface.

A method of producing a housing, the method comprising:

• forming a first plate and a second plate, the second plate facing in a direction opposite to that of the first plate, and
• forming a processing portion at a corresponding location inside a cavity of an injection mold corresponding to a gate mark receiving portion configured to receive at least one gate mark formed in each of a plurality of side surfaces of the housing, wherein the plurality of side surfaces enclose a space between the first plate and the second plate;
• and
• forming the housing through solidification of a resin comprising a predetermined amount of rigidity reinforcing material injected through a side gate connected to the cavity,
• wherein the processing portion comprises a protrusion disposed inside the cavity of the infection mold, and the processing portion comprising a side gate, and
• wherein the gate mark receiving portion comprises a gate mark receiving groove formed lower than a surface of each of the plurality of side surfaces by the protrusion at a corresponding position of a side member and comprising the at least one gate mark.
