Stacking and Palletising Protective Cases
A stack is safe when the load travels through the shell walls and the stacking rims rather than through the lid panel. That depends on rim geometry, wall thickness, how squarely one case locates on the next, and whether the cases are empty or loaded — an empty case stacked under load behaves very differently from a full one.
Key points
- A shallow locating rim lets cases shift sideways in transit; that is what collapses a stack, not compression.
- Wall thickness is the published number to compare, typically 2.0 to 5.0 mm on this type of case.
- A stack that is stable in week one can fail in month six if the foam or shell creeps under static load.
- Choose an external footprint that divides cleanly into a 1,200 × 1,000 mm or 1,200 × 800 mm pallet.
The load path
In a well-designed stack the upper case rests on the rims and walls of the lower case, and the lid panel of the lower case carries nothing at all. Where the geometry puts the upper case partly on the lid, the lid bows, the latch compression changes, and the first thing you notice is that the seal has stopped sealing.
Pallet planning
Applications
This matters most where the case is part of a movement chain rather than shelf packaging. In military and industrial equipment the same shell is specified differently because the handling, the environment and the verification requirement differ.
- Military — Military equipment moves through a chain of handlers, none of whom own the equipment and all of …
- Industrial Equipment — In an industrial setting the case is a working surface as much as a container, and its interior …
Customisation
Everything described above is configurable on a standard shell: interior layout (pick-and-pluck, die-cut or CNC-cut), foam grade and thickness, colour, logo method, latch and lock count, pressure-equalisation valve, cable ports, document holder and identification plate. A bespoke exterior geometry requires a new mould — 125 days, from 3,000 units per moulded component.
Procurement considerations
| Question | What to send us |
|---|---|
| Which shell fits? | Equipment L × W × H as packed, plus required clearance per axis |
| What does it cost? | Order quantity and estimated annual quantity — the two drive different answers |
| Is tooling needed? | Whether an existing shell clears the envelope with usable foam depth |
| Lead time? | Your required delivery date, not just the order date |
| Certification? | The exact standard your tender names — we will say whether we can test to it |
| Freight? | Destination and preferred terms; carton and pallet data supplied with the quotation |
Comparison and selection guide
The tables on this page exist because a protective case is chosen by comparing three things: the envelope, the environment and the handling chain. Where no table applies, the rule below is.
| Situation | What To Do |
|---|---|
| Fixed installation | Choose a box whose external height matches your racking pitch, and check the narrow internal width if the shell tapers. |
| Mobile use | Prefer a four-latch configuration and a lid that can be removed cleanly with gloves. |
| Inventory control | Specify a foam or partition layout so that a shortage is visible without opening compartments. |
- Size on internal dimensions plus clearance, never on a product name.
- Choose the carrying method before the shell: it changes the series, not just the price.
- Specify the interior last, and decide up front whether the end user will reconfigure it.
