Waterproof Power Supply Enclosure

Cangzhou Mengqi Hardware Products Co., Ltd. is one of the leading manufacturers and suppliers of waterproof power supply enclosure in China. Please feel free to buy cheap waterproof power supply enclosure made in China here from our factory. All customized products are with high quality and low price.

Waterproof power supply enclosures are robust electrical housings built with waterproof, dustproof and anti-corrosion performance. They effectively block moisture, dirt and contaminants from the outside, maintaining stable operation of power units under harsh working conditions. These enclosures are widely deployed for outdoor facilities, especially humid locations, including LED street lamps, landscape garden lighting and tunnel lighting. The casings withstand long-term exposure to sunlight, rain and dramatic temperature fluctuations, protecting internal power equipment reliably. Mengqi provides full customization solutions. We adjust overall dimensions, surface color and installation layouts as requested. Internal structures can also be reworked according to your power module specifications, such as adding divider plates and mounting studs to satisfy personalized assembly demands

Well-thought-out structural design is fundamental for qualified waterproof power supply housings. Material selection needs to balance ingress protection, heat dissipation and practical working environments. Metal materials remain the mainstream option, thanks to outstanding heat conduction, mechanical rigidity and EMI shielding performance, perfectly suited for demanding outdoor conditions

Aluminum Alloy： Light weight paired with superior heat dissipation capability. Proper surface finishing greatly improves corrosion resistance, ideal for high-power outdoor equipment operating under high ambient temperatures;

Stainless Steel： Excellent salt spray resistance. Available surface treatments include wire drawing, polishing and powder coating. It delivers exceptional mechanical strength and wear resistance, the top choice for coastal, marine and chemical corrosive environments;

Cold Rolled Steel Sheet： Cost-effective material with solid structural strength. Usually finished with electrostatic powder spraying, mostly recommended for indoor installation scenarios

Strict precision standards mean most waterproof power supply enclosures are made to custom specifications. We oversee every stage of production, starting from raw material inspection, precision machining, performance testing through to final shipment, to ensure finished housings fully match your technical requirements

Structural Customization

For high-power power modules, we design dense heat dissipation fins or internal ventilation openings. Cutouts can be customized to match terminal layouts, and reserved mounting positions for cable fixing brackets are available;

Material Customization

We select materials according to operating conditions. Aluminum alloy is preferred for lightweight, heat-critical projects such as charging pile power modules; stainless steel is offered for marine platforms and heavily corrosive environments;

Sealing System Customization

We adopt dual sealing solutions combining sealing gaskets and engineered housing structures. Silicone gaskets are standard for general environments, while fluorine rubber gaskets are used for chemical exposure. We supply single-groove embedded sealing or double-groove sealing structures to stop water penetration along assembly gaps

We support 48-hour rush sampling for small-batch custom projects. Our customization service focuses on accurate technical matching, stable production lead time and complete after-sales support, making sure each custom enclosure works reliably in its target application

The lead time of custom waterproof power supply enclosures depends on design complexity, order volume and testing standards. Reference production cycles are listed below：

Basic Prototyping： Simple structures without complex machining can finish sampling within 48 hours; regular prototype delivery takes 3–5 working days;

Small Batch Production： Orders ranging from 1 to 50 units normally take 7–10 working days after sampling confirmation. Complex designs will require extended lead time;

Mass Bulk Orders： Orders above 500 units will be arranged on automated stamping production lines, with standard lead time of 15 working days;

Rush arrangement is available for urgent projects. We suggest overseas buyers arrange orders in advance to avoid delays to your project schedule
