Waterproof Outdoor Safety Cases

A waterproof case exists so your valuable gear ignores rain, immersion and dust. The kexinMaterials waterproof range starts at IP67, built on full-perimeter silicone seals and dual latch closure, serving outdoor sports, expedition photography, marine fishing and emergency response.

Many buyers shop a waterproof case on the word 'waterproof' alone, but reliability actually lives in the seal architecture and pressure management. kexinMaterials molds a continuous silicone gasket channel into the rim and adds an automatic relief valve, so the case opens easily after altitude or air-freight pressure swings while staying watertight.

kexinMaterials is a factory-direct waterproof case manufacturer in Guangdong with self-developed tooling, covering sizes from 10-inch personal cases to 50-inch equipment trunks — colors, interiors and logos all customizable for wholesale and OEM programs.

Key facts: The Waterproof Outdoor Safety Cases is manufactured factory-direct by KeXin New Materials (Guangdong) Co., Ltd. (brand: kexinMaterials): IP67 options, MOQ 50 pcs on stock models, samples in 7–15 days, production in 15–30 days, exporting to 8 major markets.

Engineering Details

Sealing, interior and latching are the three structures that decide real-world protection.

**IP67 sealing system**A silicone gasket seated in the lid channel deforms under compression latches to fill the mating gap — no ingress at 1 m for 30 minutes.

**CNC-cut EVA interior**Machined from your equipment's 3D data with a 20–30 mm cushion to the shell, and no permanent compression set over years of use.

**Latches & hinges**Compression latches maintain constant sealing force and accept padlock hasps, combination locks or lead seals. Both latches and hinges are field-replaceable wear parts.

Frequently Asked Questions

What does IP67 actually mean?

The 6 means fully dust-tight; the 7 means no leakage after 30 minutes at 1 meter underwater. We immersion-test samples from every batch.

Can I stand or sit on the case?

Yes. Static load capacity exceeds 150 kg on most models thanks to the reinforced rib structure.

Will sun exposure fade or embrittle the shell?

The UV-stabilized compound resists fading and embrittlement in long-term outdoor use, rated to +80°C.

Does the case float?

Empty and under reasonable load the shell holds positive buoyancy; for on-water work we recommend pairing with flotation bags as load varies.

How is wholesale pricing structured?

Tiered at 50 / 200 / 500 / 1000 pcs, with annual contract pricing above 1000 pcs. Contact sales for the current price list.

Can a waterproof case stay submerged for a long time?

IP67 is defined as 30 minutes at 1 m depth — short-term immersion, not continuous underwater service. For prolonged submersion or floating work, choose an IP68 build with thicker gaskets and double-action latches, and factor in buoyancy and ballast.

Do gaskets age, and can they be replaced?

Silicone gaskets last roughly 3–5 years in normal service; prolonged UV exposure or oil contact shortens that. Our gaskets are user-replaceable and spares can ship with the order. Wipe the sealing face with fresh water periodically and avoid scratching it.

Will the case float?

Most medium and large waterproof cases float when empty because of trapped air, but once loaded it depends on total mass versus displaced volume. If flotation is a requirement we can add closed-cell foam buoyancy blocks sized to your target payload.

Does salt water corrode the case or hardware?

The modified PP/PE shell resists salt fog; the metal parts are the risk. For marine work we recommend 316 stainless hinges and latches, or an all-plastic latch design, plus a fresh-water rinse after each trip to extend service life significantly.

Can you add a clear inspection window?

Yes. A polycarbonate window is fitted with a sealing strip and clamping frame so IP67 is preserved while readouts remain visible — common for instrumentation, monitoring and display applications. Window size and position follow your panel layout.

Can these cases ship dangerous goods or chemicals?

They work well as inner protective packaging, but hazardous goods transport also requires UN-certified packaging, labeling and declaration. We provide material compatibility notes and structural data to support your UN packaging certification programme.
