WE HAVE OUR OWN FACTORY OEM/ODM

Extreme Environment Expertise

Specializing in rugged enclosures, we offer waterproof ratings from IP30 to IP68 (1m submersion) and NEMA 6P for underwater use. Our materials—316L stainless steel (1,000-hour salt spray tested), FRP (pH 2-12 resistance), and EMI-shielded aluminum—excel in harsh conditions. ATEX/IECEx-certified models ensure safety in explosive zones, ideal for oil, gas, and chemical sectors.

7-Day Customization & Digital-first Delivery

Leverage AI-driven tools for 7-day customization (CNC machining, logo printing, Pantone colors), ideal for small batches (≥1 unit). Pre-assembled “Waterproof Packages” with DIN rails and cable glands save 80% installation time. Enjoy global DDP shipping, free standard samples, and refundable custom samples for streamlined international orders.

Global Compliance Made Simple

We eliminate international regulatory barriers with pre-certified enclosures for UL, CE, AS/NZS, and GB standards. Our real-time tariff calculator ensures transparent import costs, while multi-region certifications cut approval delays—ideal for global deployments in the EU, APAC, or North America. No need to juggle vendors or local testing: we deliver fully compliant solutions, so you can launch faster across markets.

Explosion-Proof Junction Boxes

ExEngineered for rugged environments, our IP66 explosion-proof cast aluminum junction boxes ensure secure electrical connections in harsh conditions. Crafted from high-strength cast aluminum with an anti-corrosion anodized finish, these boxes combine durability with safety.


Core Advantages:​

Superior Protection​:

With an IP66 rating, these boxes resist dust ingress and high-pressure water jets. Their explosion-proof design meets strict safety standards, preventing ignition in hazardous areas.​

Robust Build​:

The cast aluminum construction offers excellent impact resistance, enduring rough handling. The anodized surface enhances corrosion resistance, ideal for coastal, chemical, or industrial settings. This ensures a long lifespan and low maintenance.​

Flexible Configuration​:

Choose from TB, TBC, UK, and flame-retardant U-shaped terminals, handling 10A/600V - 32A/800V. PG9/PG11 cable glands manage 4 - 10mm cables, with 1 - 6 entry/exit points for varied wiring needs.​

Custom Waterproof Enclosures

Startup Enablement - InnoTech Robotics, Singapore

For InnoTech Robotics, a startup with big dreams, finding a supplier for less than 1,000 units seemed like an impossible task—until they came to us. With our zero MOQ, 500 laser-etched housings, and no tooling fees, we made their launch a reality. They not only achieved 183% of their crowdfunding goal but also secured $80,000 in Seed funding. If you're a startup with innovative ideas, our waterproof enclosures are the gateway to turning your vision into a successful product.

Coastal Infrastructure Solution - UrbanBuild Engineering, Australia

Coastal environments can be brutal, as UrbanBuild Engineering discovered with their coastal sockets suffering 35% annual corrosion. But our 52,000 IP66 surge-protected sockets were up for the challenge. Having passed a grueling 1,000-hr salt spray test, these sockets have stood the test of time, with zero failures over 3 years. They've even withstood Category 4 cyclones, saving UrbanBuild $42,000 per year in maintenance costs. If you're building in harsh coastal conditions, our waterproof enclosures are the reliable shield your infrastructure needs.

FAQ

What waterproof ratings and materials do your enclosures offer?

We offer a full spectrum of ratings from IP30 (basic dust protection) to IP68 (1m submersion for 30 minutes). This covers everything from indoor use to extreme outdoor/underwater environments.

Our materials include stainless steel (304/316L) for high corrosion resistance in marine and heavy industrial use; aluminum that’s lightweight with EMI/RFI shielding for electronics; polycarbonate (PC) and ABS+PC which are impact-resistant, UV-stable, and signal-penetrable for outdoor wireless devices; and fiberglass reinforced plastic (FRP), a chemical-resistant, non-conductive option for harsh environments like agriculture or explosive zones. Whatever your project demands, we have the right combination of protection and material strength.
