Which Case for Which Job: Selection by Industry and Use

Direct answer

Case selection varies less by shell than by interior and duty class: trades need tool-control interiors and drop toughness; medical and lab need cleanable surfaces, moisture control and ESD-safe foam; AV needs dense custom cavities and discreet styling; drones and cameras need precision-cut EVA and pressure valves; test instruments need rack compatibility and EMI consideration. Start from what the contents fear — impact, moisture, static, heat or theft — and specify against that fear.

§02Four questions that shortcut the decision

  1. What is the single worst transport event this case must survive (a 1.2 m drop, a week in a wet truck bed, an airline hold)?
  2. How often is it opened? — thousands of cycles move the spec toward latch and gasket quality.
  3. Who carries it? — wheels and telescoping handles above ~15 kg; shoulder straps for stair-heavy urban work.
  4. Does it fly, and how often? — airline linear limits, TSA locks, ATA-grade hardware for frequent flyers.
Cross-industry lesson: failures concentrate at the interior-shell interface — a perfect shell with a loose foam insert still lets contents migrate and break. Spend the engineering time on the foam layout; it is the cheapest insurance in the whole spec.
