Engineering Features & Details
Crush-proof protective case 500kg from Kexin integrates a series of thoughtful design features that facilitate daily professional use. TSA-approved combination locks (Travel Sentry) enable smooth customs checks during international travel without breaking the case. Automatic pressure equalisation valves (Gore-Tex membrane) compensate for altitude differences during air transport and prevent vacuum suction that would jam the case lid. O-ring seals made of NBR or silicone (temperature range -55 to +200 °C) guarantee permanent watertightness even after 5+ years of use.
Practical Details for Daily B2B Use
Ergonomic soft-grip carry handles with steel core prevent breakage under heavy load. Hidden document compartments in the lid accommodate delivery notes, declarations of conformity, and customs documents. Folding carry handles snap flush when not in use and save space in the container. Wheels with polyurethane treads (quiet, abrasion-resistant) and an extendable trolley handle make it easier to transport cases over 15 kg. All external fittings are made of V2A / V4A stainless steel (1.4301 / 1.4404), corrosion-free even in salty marine environments. On request we deliver custom foam inserts (PE, EVA, Pick & Pluck), abrasion-resistant exterior paint in Pantone, and your logo via screen print, laser engraving, or doming stickers.
