Engineering answers for case buyers
Straight, standards-based answers to the questions OEM buyers ask before specifying a protective case — IP ratings, materials, foam, test standards, lead times and shipping terms. No marketing filler.
DOC KB-IPR-001What Do IP Ratings Actually Mean for Protective Cases?What IP65, IP67 and IP68 are actually tested against — and which one you need.DOC KB-MAT-002PP vs ABS vs Rotomolded PE vs Aluminum: Case Materials ComparedWeight, impact, temperature and cost trade-offs between the four mainstream shell materials.DOC KB-FOM-003Foam Inserts for Protective Cases: EPE vs EVA vs PU vs CNC-CutPick the right interior foam: cushioning, presentation, or field-configurable.DOC KB-SIZ-004How to Choose the Right Protective Case SizeInternal volume, foam allowance, wheels and the 62-inch airline rule.DOC KB-STD-005Drop and Impact Standards for Protective Cases: MIL-STD-810, ATA 300 and ISTAHow to read drop-test claims: which standard, which procedure, what height.DOC KB-HDW-006Why Watertight Cases Need a Pressure Relief ValveAltitude and temperature lock latches and stress gaskets — the valve fixes both.DOC KB-HDW-007Case Gaskets, Latches and Hinges: The Hardware That Decides LifespanShell plastics get the glory; gaskets and latches decide whether it still seals in year five.DOC KB-ENV-008Protective Cases in Heat, Cold and Sunlight: Temperature and UV PerformanceWhat −40 °C to +90 °C really means on a datasheet, and why black cases outlast bright ones outdoors.DOC KB-BUY-009EXW vs FOB: Shipping Terms for Protective Case BuyersWho books what, who pays for what, and where risk changes hands.DOC KB-OEM-010Custom OEM Protective Cases: Realistic Timeline From RFQ to Shipment45 days with an existing mold, roughly 125 days when new tooling is required — here is where the time goes.DOC KB-TRV-011Flying with Equipment Cases: Airline Rules, ATA 300 and Transit PrepThe 62-inch rule, battery fine print, and why your case arrived with a bulging lid.DOC KB-BRD-012Branding a Protective Case: Pad Printing vs Laser vs In-Mold LabelingWhich logo process survives abrasion, UV and solvent — and what each costs in setup.DOC KB-MOQ-013Why Custom Cases Have a Minimum Order Quantity (and What Drives It)What actually sets the MOQ floor: color batches, foam setups and press time.DOC KB-TOL-014Injection Molding vs Rotomolding for Custom Cases: Tooling EconomicsSteel tooling vs cast tooling: where each process pays off by volume and duty.DOC KB-RFQ-015How to Write an RFQ for Custom Protective Cases (Buyer Checklist)The 12 fields that make suppliers quote accurately instead of guessing.DOC KB-QC-016Pre-Shipment Inspection for Protective Cases: What to Check and AQL BasicsAQL sampling, the 8-point functional check, and when third-party inspection pays for itself.DOC KB-LOG-017Export Packing for Protective Cases: Master Cartons, Pallets and Container LoadingFrom single case to sealed container: carton strategy, pallet patterns and cbm math.DOC KB-EMI-018EMI and RFI Shielding Cases: When Plastic Is Not EnoughAluminum shells, conductive coatings and EMI gaskets — the three paths to shielding.DOC KB-MST-019Moisture and Corrosion Control Inside Protective CasesA sealed case is also a humidity box — desiccants, indicator cards and VCI done right.DOC KB-IND-020Which Case for Which Job: Selection by Industry and UseThe same shell serves many trades; the interior, sealing class and wheels change.DOC KB-ECO-021Recyclability of Protective Cases: PP, PE and Designing for End of LifeMono-material shells are widely recyclable; the foam and mixed hardware are the challenge.
