## Applications

- [Military](https://kexincases.com/applications/military/) — Military equipment moves through a chain of handlers, none of whom own the equipment and all of whom will drop it. Case selection in that environment is a logis
- [Defense](https://kexincases.com/applications/defense/) — Defence support equipment is the unglamorous half of the inventory — test sets, spares, ground power, cabling, calibration kits — and it is the half most often 
- [Law Enforcement](https://kexincases.com/applications/law-enforcement/) — A police or rescue kit is opened at an incident, in poor light, often while wearing gloves, and its contents sometimes have evidential status. Those three facts
- [Firearm Transportation](https://kexincases.com/applications/firearm-transport/) — This page is about the packaging problem: how a long, rigid, awkwardly balanced item is protected and constrained inside a shell. KeXin manufactures cases only.
- [Ammunition & Inventory Transport](https://kexincases.com/applications/ammunition-transport/) — Storage boxes are bought by the pallet-load, and the numbers that matter are volume, stacking behaviour, closure quality and carton packing — not advertising co
- [Outdoor & Recreation](https://kexincases.com/applications/outdoor/) — Consumer and professional outdoor brands buy cases as a component of their product. That means colour, finish, weight and a repeatable supply programme matter a
- [Aerospace & Avionics](https://kexincases.com/applications/aerospace/) — In aviation ground support, the case is part of the tooling chain and its mass is a direct cost. Every gram of shell is a gram that is not available for the pay
- [Electronics & Instruments](https://kexincases.com/applications/electronics/) — Electronic assemblies rarely fail from a single large impact. They fail from repeated small shocks, from a connector that carried load, and from dust in an inte
- [Medical & Laboratory](https://kexincases.com/applications/medical/) — Medical cases are audited. Whatever goes inside has to be verifiable at a glance, cleanable, and protected to the standard the device manufacturer intended.
- [Industrial Equipment](https://kexincases.com/applications/industrial-equipment/) — In an industrial setting the case is a working surface as much as a container, and its interior is an inventory control device.
- [Telecommunications](https://kexincases.com/applications/telecommunications/) — Communications equipment is never one object. It is a unit plus a set of accessories that determine whether the unit works, and the accessories are what get dam
- [Drone & UAV Operations](https://kexincases.com/applications/drones/) — A drone kit is three different protection problems in one box: a light awkward airframe, heavy batteries, and a gimbal that must not be touched.
- [Field & Deployment](https://kexincases.com/applications/field-equipment/) — Field deployment removes every assumption a depot specification makes: no forklift, no dry storage, no control over who opens the case.

## Knowledge center (citable technical answers)

- [How To Choose A Protective Case: The Seven Numbers That Decide It](https://kexincases.com/knowledge-center/how-to-choose-a-protective-case/)
  - Quick answer: Choose a protective case in this order: the internal envelope of the equipment plus clearance, the packed mass and how far it must be carried, the wall thickness needed for stacking, the foam grade and thickness for the impact you expect, the closure count needed to keep the seal even, the external footprint needed for the pallet or vehicle, and finally the interior layout that makes the contents verifiable. Everything else is decoration.
- [What A Protective Case Is Made Of: Shell, Seal, Hardware And Foam](https://kexincases.com/knowledge-center/what-a-protective-case-is-made-of/)
  - Quick answer: A protective case is four systems working together: a moulded thermoplastic shell that carries impact and stacking load; a continuous lid-to-base rim with a compressible gasket that excludes dust and water; hardware — latches, hinges, handles, wheels — that forms the load path and is also the part that wears out; and a foam interior that decides what the equipment actually feels.
- [What Is A Military Protective Case?](https://kexincases.com/knowledge-center/what-is-a-military-protective-case/)
  - Quick answer: A military protective case is a reusable, hard-shell container designed to store and transport equipment while reducing exposure to impact, dust, moisture and the handling abuse of a logistics chain. It combines an injection-moulded thermoplastic shell, a compressible seal between lid and base, hardware that carries the stacking and lifting load, and a shaped foam interior that fixes the equipment in a known position.
- [Military Equipment Case Selection: Series, Size And Carrying Method](https://kexincases.com/knowledge-center/military-case-selection-guide/)
  - Quick answer: Select by internal volume band first, then by carrying method, then by interior. In the KeXin range, accessory and ammunition kits sit in the 0 and 1 series, instrument and radio kits in the 6 and 7 series, complete systems in the 8 and 9 series, and anything above roughly 12 kg packed belongs in the T series with wheels.
- [Firearm & Long Equipment Transport Case Guide](https://kexincases.com/knowledge-center/firearm-transport-case-guide/)
  - Quick answer: A long item inside a long case behaves as a beam. When the case is carried at the ends the shell flexes in the middle, and anything rigid inside shares that flex. The specification therefore has four parts: internal length with clearance at both ends, a lid-to-base depth split that puts the mass in the base, latches spaced along the long edge, and an interior that supports the item at two points rather than bridging its whole length.
- [Ammunition & Inventory Storage Box Guide](https://kexincases.com/knowledge-center/ammunition-storage-box-guide/)
  - Quick answer: A storage box is bought as a system, not as an object. The four numbers that decide whether it works are internal volume, wall thickness, the lid-to-base depth split, and the carton data that lets you plan a pallet. Everything else — colour, latch style, division — follows from those.
- [Foam Inserts For Protective Cases: Types, Layers And Selection](https://kexincases.com/knowledge-center/foam-insert-guide-for-protective-cases/)
  - Quick answer: A foam insert is chosen by three independent decisions: how it is made (pluck, die-cut or CNC-cut), what it is made of (EVA, cross-linked PE, EPE, EPS), and how it is layered (a firm carrier under a soft contact layer). Precision, flexibility and cleanability trade against each other, so the correct answer depends on who reconfigures the interior and how often.
- [How Foam Thickness And Density Are Chosen](https://kexincases.com/knowledge-center/how-foam-thickness-is-chosen/)
  - Quick answer: Thickness sets the stopping distance and therefore the peak force transmitted during an impact. Density and grade set how much the foam recovers under a sustained load. A case can have plenty of thickness and still fail if the foam creeps under the equipment mass over months, and it can have the perfect density and fail because there was only 20 mm of it.
- [How Waterproof Cases Actually Work](https://kexincases.com/knowledge-center/how-waterproof-cases-work/)
  - Quick answer: A waterproof case compresses a gasket between the lid and the base along a continuous, uninterrupted rim, using enough latches that the compression in the middle of the longest edge is close to the compression at the corners. If either half of that sentence is missing, the case will leak at the weakest point regardless of the quality of the rubber.
- [What An IP Rating Does Not Tell You](https://kexincases.com/knowledge-center/what-ip-rating-does-not-tell-you/)
  - Quick answer: An IP code is the result of one test protocol on one assembly under laboratory conditions. It tells you that a specific sample passed a specific procedure. It does not tell you how the case behaves after a year of field handling, whether the seal survives grit, or whether the same result will be obtained on a different production batch.
- [PP vs ABS Protective Cases](https://kexincases.com/knowledge-center/pp-vs-abs-protective-cases/)
  - Quick answer: PP wins on chemical resistance, low-temperature toughness and cost per unit of impact performance, which is why it accounts for the majority of the KeXin range. ABS wins on panel stiffness, surface finish and print quality, which is why it is preferred where a case is a brand-facing product.
- [Protective Case Procurement Checklist](https://kexincases.com/knowledge-center/protective-case-procurement-checklist/)
  - Quick answer: A quotable protective case enquiry contains eleven items: equipment length, width, height and mass; quantity; annual estimate; application; required protection; interior preference; logo and colour; target market; and delivery terms. Anything less produces a price range rather than a price.
- [MOQ, Tooling And Unit Cost: How They Interact](https://kexincases.com/knowledge-center/moq-tooling-and-unit-cost/)
  - Quick answer: Three different MOQs apply to one case. A stocked shell accepts a single unit. A custom colour, logo or interior normally starts around 300 units because a fixture or a colour batch has to be set up. A bespoke shell geometry starts around 3,000 units per moulded component, because the mould is a capital cost that has to be recovered.
- [Internal Versus External Dimensions](https://kexincases.com/knowledge-center/internal-vs-external-dimensions/)
  - Quick answer: Internal dimensions decide whether the equipment fits. External dimensions decide whether the case fits a pallet, a rack, a vehicle or an airline limit. The difference between the two is the wall, the rim, the latch profile and the handle, and on a thick-walled case it can be 20-40 mm per axis.
- [Container Loading For Protective Cases](https://kexincases.com/knowledge-center/container-loading-for-protective-cases/)
  - Quick answer: Work from the carton, not the case. Take carton length, width and height and pieces per carton, build a pallet footprint that divides into 1,200 x 1,000 mm or 1,200 x 800 mm without an overhang, set a stack height within the pallet and product limits, then divide the usable container volume by the pallet volume and check the door height.
- [Protective Case Factory Versus Trading Company](https://kexincases.com/knowledge-center/factory-versus-trading-company/)
  - Quick answer: A manufacturer can show you a mould number for the case you are buying, a machine list with clamping tonnages matched to the case size, a dimensional report measured on a production unit, and serviceable spare parts for the hardware. A reseller can usually show you photographs.
- [How To Measure Equipment For A Case](https://kexincases.com/knowledge-center/how-to-measure-equipment-for-a-case/)
  - Quick answer: Measure the equipment as it will actually be packed, not as it is on the bench. Record the maximum extent in each of the three axes including anything that stays attached, weigh the complete packed kit, measure the accessory set separately, and add 20 mm of clearance per axis before you look at a catalogue.
- [Engineering Plastics In Protective Cases](https://kexincases.com/knowledge-center/engineering-plastics-in-cases/)
  - Quick answer: Engineering-grade PP is a polypropylene formulation modified for predictable mechanical behaviour — typically a copolymer with rubber phase, a nucleating agent or a mineral filler — so that stiffness, low-temperature toughness and creep resistance are held within a stated range rather than left to a general-purpose grade.
- [How a Protective Case Matching Engine Works](https://kexincases.com/knowledge-center/how-a-case-matching-engine-works/)
  - Quick answer: A case matching engine filters a product database on internal length, width and height against the equipment envelope plus a clearance allowance, then removes candidates that fail weight, feature and application constraints, then ranks what remains by unused volume, evenness of clearance, empty mass and feature bonuses, and finally returns three tiers rather than one answer.
- [OEM vs ODM vs Private Label Protective Cases](https://kexincases.com/knowledge-center/oem-vs-odm-vs-private-label/)
  - Quick answer: OEM means you supply the design and the factory builds it. ODM means the factory starts from its own shell and engineers the interior, hardware and finish to your requirement. Private label means an ODM relationship plus your brand, colour, logo and retail packing on a repeatable replenishment schedule. Only OEM with a new exterior geometry needs a mould.
- [How To Read A Protective Case Datasheet](https://kexincases.com/knowledge-center/how-to-read-a-protective-case-datasheet/)
  - Quick answer: A protective case datasheet has four groups of numbers: the envelope (internal and external dimensions, narrow internal width, lid and base depth split), the structure (wall thickness, material, hardware), the mass (net and gross) and the logistics block (carton dimensions, pieces per carton, pallet and container figures). Read the internal envelope first and the marketing copy last.
- [Stacking and Palletising Protective Cases](https://kexincases.com/knowledge-center/stacking-and-palletising-protective-cases/)
  - Quick answer: 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.
- [Pressure Equalisation Valves Explained](https://kexincases.com/knowledge-center/pressure-equalisation-valves-explained/)
  - Quick answer: A pressure equalisation valve lets air move in and out of a sealed case so the internal and external pressure equalise. It solves vacuum lock — a warm case cooled quickly develops a partial vacuum that makes the lid hard to open and pulls outside air, with its dust, through the seal the moment you crack it open. It is not a waterproofing device.
- [Case Hardware: Latches, Hinges, Handles and Wheels](https://kexincases.com/knowledge-center/case-hardware-latches-hinges-wheels/)
  - Quick answer: Hardware is the part of a protective case that wears out, and it is also the part that decides whether the seal stays compressed and whether the case can be opened with gloves in the dark. Specify hardware by count, by load path and by replaceability, and order a spares kit with the production batch.
- [Military Case vs Industrial Case: What Actually Differs](https://kexincases.com/knowledge-center/military-case-vs-industrial-case/)
  - Quick answer: The difference is not the plastic. A military case is specified for a handling chain it does not control — dropped from a tailgate, stacked in a hold, opened with gloves in the dark, and audited for contents. An industrial case is specified for a controlled workshop or a technician call-out, where tool control and calibration traceability matter more than survivability.
