IP67 fully sealed waterproof and dustproof hard box

What Does IP67 Mean?

Professional-Grade Environmental Protection Solution
WEISHUO's IP67 fully sealed waterproof and dustproof hard box is designed for users who need to protect important items in extreme environments. The case uses a precise one-piece molding process and multiple sealing technologies, fully meeting and exceeding the IP67 international protection rating standard. Whether for outdoor adventures, industrial sites, underwater operations, or laboratory environments, our protective cases provide the most reliable all-around protection. Each case undergoes a rigorous quality control process in our own factory to ensure stable and reliable sealing performance.

The IP (Ingress Protection) rating is defined by the IEC 60529 standard and is used to quantify the level of protection provided by the enclosure of electrical equipment against the ingress of solid foreign objects and liquid moisture.

IP67 is a combination of two independent tests. The dust protection test (IP6X) takes 8 hours, and the water protection test (IPX7) takes 30 minutes. A device must pass both tests to obtain IP67 certification.
Note: IP67 stands for “protection against brief immersion”—according to the IEC 60529 standard, this refers to immersion in 1 meter of water for 30 minutes. It is not diving-grade protection (which falls under IP68), but rather a reliable seal designed for heavy rain, accidental drops into water, and washing scenarios.

How Do We Test? — Not Just in the Lab, but in Real-World Environments

1. Standard Laboratory Testing

All IP67 fully sealed waterproof and dustproof hard cases have undergone rigorous testing at third-party CNAS/CMA-accredited laboratories.

2. Real-World Field Tracking Tests

Passing laboratory tests is the foundation, but real-world environments are the true test. We conducted continuous, multi-scenario tracking tests on the IP67 fully sealed waterproof and dustproof hard box for 6 months:
• Test Period: 6 months
• Test Scenarios: Coastal salt fog environment, desert exposure to intense sunlight, heavy rain and muddy conditions, industrial dust workshops
• Average Load: 10–15 kg (simulating communication equipment, testing instruments, controllers, etc.)
Results: During six months of real-world use, the protective case endured more than 40 instances of drops, collisions, and exposure to extreme weather conditions of varying severity. The case’s sealing performance remained consistently stable—the interior remained dry after being submerged in heavy rain, no dust penetrated in industrial dust environments, and no rust formed on metal hardware in coastal salt fog environments. During every inspection upon opening the case, the internal equipment was found to be intact.

3. Long-Term Validation of the Sealing System

IP67 is not a “label” obtained through a one-time test, but rather a performance standard that must be maintained throughout the product’s entire lifecycle. WEISHUO’s sealing system ensures long-term reliability through the following design features:
• Wide silicone sealing gaskets: With a temperature range of -30°C to 90°C, they retain their elasticity even under extreme temperatures
• Precision sealing groove design: Ensures even pressure distribution on the gaskets, eliminating weak points
• Metal-reinforced latches: Provide stable locking force, ensuring a tight seal between the lid and the case
• Pressure equalization valve: Regulates internal and external air pressure, suitable for air transport and high-altitude environments

Real-World Scenarios

Scenario 1: Desert Solar Power Plant

A solar power plant located on the edge of a desert experiences strong winds and sandstorms, as well as significant temperature fluctuations between day and night. In the past, equipment frequently malfunctioned due to sand and dust intrusion. After introducing IP67-rated sealed enclosures, equipment operational stability improved significantly, and power generation efficiency increased by approximately 8% as a result of reduced failures.
WEISHUO’s Contribution: The IP6X dust-tight rating ensures that even the finest sand particles cannot penetrate the enclosure; the wide-temperature-range sealing system withstands the extreme temperature fluctuations in the desert, ranging from 60°C during the day to near 0°C at night.

Scenario 2: Coastal Communication Base Stations

The greatest threat to equipment enclosures at coastal base stations is salt fog corrosion. With ordinary enclosures, latches can rust shut and seals can fail within just a few months of exposure to sea winds. WEISHUO enclosures utilize stainless steel hardware and salt-fog-resistant materials, achieving a corrosion rating of ≥9 in a 720-hour salt fog test (in accordance with ISO 9227), ensuring reliable long-term use in coastal environments.

Scenario 3: Industrial Dust-Filled Workshops

In workshops within industries such as cement, chemicals, and grain processing, large amounts of dust are suspended in the air. Standard equipment enclosures become filled with dust inside after just a few months, leading to short circuits on circuit boards and poor heat dissipation. WEISHUO protective enclosures feature an IP6X dust-tight rating, ensuring the interior remains clean at all times.

Scenario 4: Outdoor Operations in Heavy Rain

In scenarios such as outdoor surveys, emergency response, and communications support, equipment is frequently exposed to heavy rain. The IPX7 waterproof rating of WEISHUO protective enclosures ensures no water ingress after 30 minutes of immersion in 1 meter of water—meaning that even if the enclosure accidentally falls into a puddle or is washed by heavy rain, the internal equipment remains safe.

FAQ

Q1: What exactly does the IP67 protection rating mean?
A1: IP67 is defined according to IEC 60529 standard. The first digit "6" means complete dustproof protection (sample under negative pressure, exposed to 2kg/m³ dust concentration for 8 hours, no dust ingress). The second digit "7" means protection against temporary immersion (sample fully submerged in 1 meter of water for 30 minutes, no water ingress). Both tests must be passed to obtain IP67 certification.

Q2: Can Weishuo customize the case size and color?
A2: Yes. We provide OEM/ODM deep customization services including case size, exterior color (Pantone/RAL color matching), logo printing, foam interior layout, pressure balance valve, custom cutouts, and more — all tailored to your specific requirements.

Q3: What equipment and scenarios is this case suitable for?
A3: It is suitable for outdoor power facilities, telecom base stations, industrial sites, emergency rescue, marine and shipping, transportation and other scenarios, accommodating communication equipment, controllers, sensors, testing instruments, electrical components, outdoor monitoring devices, etc.

Q4: Will the sealing performance degrade after long-term use?
A4: No. The case features a wide silicone sealing gasket with a temperature range of -40°C to 90°C, maintaining elasticity even in extreme temperatures. Combined with a precision sealing groove design and metal-reinforced latches, the sealing system ensures uniform pressure distribution on the gasket for long-term reliable sealing performance.

Q5: Can the case accommodate air transport or high-altitude environments?
A5: Yes. The case can be equipped with an automatic pressure balance valve featuring a waterproof breathable membrane. It maintains IP67 sealing while automatically equalizing internal and external pressure differences, effectively solving the issue of case lids being unable to open due to pressure changes during air freight or in high-altitude regions.
