unmold

Unmold is a verb meaning to remove a molded object from its mold after it has formed. The term applies across fields such as cooking, manufacturing, and sculpture. Variants include unmould (British English) and the corresponding forms unmolded or unmoulded.

In cooking and baking, unmolding is often the final step in presenting a shaped dessert or savory dish. Molds can be silicone, metal, or plastic, and practitioners use greasing, flouring, or a release agent to aid release. Delicate or gelatin-based items, custards, and frozen creations are typically cooled or set fully before turning out. The mold is inverted onto a plate or platter, and the dish is allowed to slide out cleanly.

In manufacturing and industrial contexts, unmolding refers to removing a cured or solidified part from its mold after the material has set. This includes plastics, resins, ceramics, and metals. Complex or two-part molds may require mechanical ejection or separation along parting lines. Release agents, proper mold design, and temperature control help minimize sticking, tearing, or flash (thin excess material) during unmolding. Post-mold finishing may follow, such as trimming, polishing, or additional curing.

Safety and quality considerations include ensuring the part is adequately set before unmolding, selecting compatible mold releases, and handling hot or sharp components with care. Proper unmolding reduces defects and facilitates efficient production or presentation.
