      "definition": "Casting resin around a pack or circuit in a mould that is removed once the resin cures, so that the cured resin itself becomes the outer case. Unlike potting, which fills a housing that stays, it needs no separate enclosure; casting under vacuum removes air voids. Both seal against water and vibration, and both make a pack hard to repair or recycle.",
