The ChefAide 28-cube system uses a hybrid-material construction designed to provide the benefits of both rigid plastic and flexible silicone. The upper frame is made from high-density polypropylene, which offers the structural integrity needed to stack multiple units without them compressing. The "easy-release" functionality is located at the base of each cell, which uses a thermoplastic elastomer (TPE) to allow you to pop individual cubes out with localized pressure.
A practical feature of this set is the recessed lid-locking groove, which helps keep the lid securely in place even when frost builds up in the freezer. While the lid helps prevent the ice from absorbing surrounding food odors, it is not designed to be watertight; it should only be used for stacking and odor protection while the tray is level. Specifications indicate that the material remains ductile down to -30°C, adding a layer of durability for long-term use.
To ensure the release mechanism works as intended, it is recommended to leave about 2mm of clearance at the top when filling, as the water will expand as it freezes. While the trays are dishwasher safe, frequent exposure to high-heat drying cycles may eventually warp the lid seal. This system is an excellent choice for those who want to avoid the material fatigue and cracking common in traditional all-plastic trays.
If you require a system that includes a built-in press mechanism for even faster harvesting, the Brigii 56-cube press system is a high-volume alternative.
