The inspiration for this automotive radar housing came from a critical challenge we noticed during a collaboration with a northern Chinese automaker: in winter, their radar modules frequently failed due to brittle cracking of the original plastic housing under -30℃ temperatures, leading to delayed vehicle deliveries and increased after-sales costs. This experience drove our team to rethink radar housing design—not just as a "cover," but as a "protective barrier" for vehicle safety.
Material Selection: Adopts 30% glass fiber-reinforced PA66, a material widely recognized in the automotive industry for its balance of strength and lightness. Compared to ordinary ABS plastic, its impact resistance is increased by 60%, and its tensile strength reaches 85MPa—enough to withstand the collision of small debris during driving without damaging the internal radar components.
Sensory Advantage: The material has a matte texture that doesn’t reflect sunlight, avoiding glare that could interfere with nearby sensors. When tapped lightly, it emits a dull, solid sound (not a hollow rattle), a subtle sign of its structural integrity.
Chemical Resistance: Resists erosion from common automotive fluids (engine oil, brake fluid, rainwater) and industrial cleaning agents. Even if the housing comes into contact with these substances for a long time, it won’t swell or peel—extending the radar’s service life by 3-5 years.
Dustproof & Waterproof: Meets IP6K9K standards—the highest level of protection for automotive components. It can withstand 8 hours of continuous dust exposure (simulating desert conditions) without any dust entering the interior. In high-pressure car washes (80℃ hot water, 10MPa pressure), water won’t seep into the radar module, preventing short circuits.
Salt Spray Resistance: Passes 500-hour neutral salt spray testing (equivalent to 5 years of coastal use). The surface coating forms a protective film that blocks chloride ions in sea breeze, avoiding rust or corrosion of the housing’s internal mounting points.
Sealing Detail: Uses food-grade silicone gaskets (compliant with FDA standards) between the housing and radar module. The gasket is soft to the touch, with good elasticity—ensuring a tight seal even after 10,000 times of vibration (simulating long-distance driving on rough roads).
Extreme Cold Performance: In -40℃ environments (simulating northern winter nights), the housing remains flexible. After 24 hours of low-temperature storage, it can still withstand a 1.5m drop test without cracking—critical for regions with severe cold.
High-Temperature Stability: At 85℃ (simulating summer sun exposure on car bumpers), the housing’s dimensional change rate is less than 0.2%. This ensures the radar’s antenna alignment remains accurate, avoiding signal deviation that could cause ADAS functions (like adaptive cruise control) to fail.
Temperature Cycle Durability: Passes 1,000 cycles of -40℃ to 85℃ temperature shocks. After testing, the housing’s color, strength, and sealing performance remain unchanged—proving its reliability for long-term use.
Broad Compatibility: Fits mainstream radar modules from brands like Bosch, Continental, Huawei, and Desay SV. The internal cavity size covers 50-150mm (length) × 30-80mm (width) × 20-50mm (height), meeting the needs of most L2-L4 autonomous driving systems.
Tight Tolerance Control: Uses precision injection molding (CNC molds with ±0.05mm accuracy), so the housing’s dimensional tolerance is controlled within ±0.1mm. This ensures a perfect fit with the radar module, eliminating gaps that could cause noise or water leakage.
Easy Installation: Designed with 4 pre-threaded mounting holes (M3 size) and 2 positioning pins. Workers can complete installation in 2 minutes with a standard screwdriver—reducing assembly time for automakers and improving production efficiency.
