Shanghai – TOBO GROUP, a leader in advanced corrosion testing technology, is proud to launch the MetaCorr 360 Salt Spray Analyzer—a breakthrough system engineered to solve a critical challenge in corrosion testing: uniform evaluation of complex, irregularly shaped components. Tailored for industries like aerospace, heavy machinery, and custom metal fabrication, this analyzer uses 360-degree sensing and dynamic mist distribution to ensure every surface of a component—from curved engine blades to threaded fasteners—receives equal exposure and precise monitoring.
At the core of the MetaCorr 360 is its 3D sensing array, featuring 24 micro-sensors embedded in a rotating ring that surrounds the test chamber. Unlike traditional testers with fixed sensors (which often miss corrosion on hidden or curved surfaces), these sensors move in sync with a dual-axis specimen turntable (rotating 360° horizontally and tilting 15° vertically), capturing data from every angle. For example, when testing an aerospace turbine blade with intricate airfoils, the sensors detect corrosion initiation on the blade’s trailing edge—an area that would typically be overlooked by static sensors. An aerospace component manufacturer reported that this 360-degree monitoring reduced their "missed defect" rate by 80% compared to their previous tester.
Complementing the sensing array is the analyzer’s dynamic fog delivery system, which uses 12 adjustable nozzles (6 upper, 6 lower) that adapt their spray angle and pressure based on the specimen’s shape. A built-in 3D scanner first maps the component’s geometry, then the system calibrates nozzle settings to eliminate "shadow zones"—areas where mist might be blocked by the component’s structure. For heavy machinery manufacturers testing hydraulic valves with recessed ports, this means the mist reaches deep into the ports, simulating real-world exposure to salt-laden dust or moisture. A construction equipment brand used this feature to test excavator bucket teeth, ensuring even corrosion testing on both the tooth tip and the backside mounting bracket.
Precision meets industry standards with the MetaCorr 360’s environmental control suite, which maintains temperature within ±0.2°C, salt concentration (3-5% NaCl) within ±0.03%, and humidity at 95% RH—compliant with ASTM B117, ISO 9227, and SAE J2334 (automotive/heavy machinery standards). The analyzer also offers customizable test protocols, such as extended cyclic testing (alternating salt spray and dry periods) to mimic seasonal weather changes. A custom metal fabricator used this cyclic mode to test decorative iron railings for coastal homes, simulating 5 years of summer salt fog and winter dryness in just 300 hours.
Data visualization is simplified via the analyzer’s 3D Corrosion Mapping software, which overlays sensor data onto the component’s 3D scan to create a color-coded "corrosion heatmap." Red zones indicate high corrosion activity, while green zones show minimal degradation—making it easy for engineers to identify weak points. A marine equipment manufacturer used this software to optimize the coating on boat propeller shafts, focusing improvements on the shaft’s keyway (a recessed area that showed high corrosion in tests). The software also generates compliance reports with timestamped data, satisfying regulatory requirements for industries like aerospace and medical devices.
Real-world applications demonstrate the analyzer’s impact across sectors. An aircraft engine maker used the MetaCorr 360 to test nickel-alloy turbine disks, detecting micro-corrosion on the disk’s bolt holes—an issue that could have led to fatigue failure in flight. A marine hardware brand tested stainless steel boat cleats, ensuring even corrosion resistance on the cleat’s curved arms and the base mounting plate. In custom fabrication, a luxury automotive restorer used the analyzer to validate vintage car chrome plating, ensuring the plating held up to coastal driving conditions without peeling on complex bumper contours.
“The MetaCorr 360 reimagines corrosion testing for components that don’t fit a box,” said TOBO GROUP’s Chief Technology Officer. “Complex parts need complex testing—and our 360-degree sensing and dynamic fog delivery ensure no surface goes unevaluated. For manufacturers, that means more reliable products, fewer recalls, and greater confidence in real-world performance.”
