• and
• a thermoplastic frame in which the modular cup arrangement is fixedly mounted by capturing the outer periphery of the modular cup arrangement to produce an integrated ice-tray of dissimilar materials;
• wherein:
• the metal cups of the first and second sets of end cups and the at least one set of intermediate cups fixedly captured by the thermoplastic frame providing an integrated structure of the ice-tray in which the openings of the metal cups face a common direction to receive water from the ice-making machine supporting the ice tray therein;

• a sensor communicating with at least one fabricated metal cup for detecting a state of water within the fabricated metal cup as being frozen or unfrozen wherein:
• the sensor is an electrode pair communicating with a circuit sensing a change in electrical properties between the electrode pair caused by a freezing of water;
• and
• the at least one fabricated metal cup defines a multi-segmented cup, including:
• a first metal bisected cup portion of the respective fabricated metal cup;
• a second metal bisected cup portion of the respective fabricated metal cup;
• a divider made from an electrically insulating material and arranged between the first and second metal bisected cup portions, the divider connected to the first metal bisected cup portion at a first side of the divider and connected to the second metal bisected cup portion at a second side of the divider providing two electrically isolated halves of the multi-segmented cup defining the at least one fabricated metal cup with the first and second metal bisected cup portions and the intermediate divider joined to each other to collectively provide a watertight structure of the multi-segmented cup;
• and
• the electrode pair of the sensor including:
• a first electrode electrically connected to the first metal bisected cup portion;
• and
• a second electrode electrically connected to the second metal bisected cup portion.

A method of fabricating an ice-tray including:(a) a set of end cups having a first configuration;

• (b) a set of intermediate cups having a second configuration, wherein each of the sets of end and intermediate cups includes metal cups, with each of the metal cups having an opening at a rim for receiving water into a cup volume during a water filling procedure, the cup volume defining a shape of an ice cube that may be frozen within the fabricated metal cups;
• and (c) a thermoplastic frame adapted to receive and retain the set of end cups and the set of intermediate cups with respect to each other with the openings of the metal cups facing in a common direction to receive water from an ice-making machine supporting the ice tray therein, the method comprising:
• (a) inserting the set of end cups and the set of intermediate cups into the thermoplastic frame;
• and
• (b) affixing the set of end cups and the set of intermediate cups to the thermoplastic frame by engaging retainers so that:
• the metal cups and the thermoplastic frame are fixed to each other to provide an integrated structure of dissimilar materials;
• and
• water passages extend across joints defined between the set of end cups and the set of intermediate cups to equalize volumes of water in the metal cups during the water filling procedure.
