Shanghai – TOBO GROUP, a leader in material-agnostic testing solutions, is proud to launch the MultiMatix Sync Salt Spray Tester—a groundbreaking system engineered to address the unique challenges of testing mixed-material assemblies (e.g., metal-plastic composites, aluminum-carbon fiber parts) and enabling direct performance comparison across dissimilar materials. Tailored for industries like automotive, aerospace, and consumer electronics—where products increasingly combine metals, polymers, ceramics, and composites—this tester eliminates the need for separate setups for each material, streamlining the validation of multi-component parts while delivering actionable cross-material corrosion data.
At the core of the MultiMatix Sync is its Material-Aware Adaptive System, which uses a built-in material sensor array to identify up to 12 common engineering materials (aluminum, steel, titanium, ABS plastic, carbon fiber, PVC, and more) within a single test batch. Once materials are identified, the system automatically calibrates zone-specific parameters—adjusting salt concentration (2-8% NaCl), temperature (23-55°C), and fog density—to match each material’s testing requirements, all while maintaining a unified test environment. For example, when testing an automotive door assembly that combines steel hinges, aluminum trim, and plastic interior panels, the MultiMatix Sync creates three “micro-zones” within its 1.0 cubic meter chamber: a 5% NaCl zone for steel (to mimic harsh underbody exposure), a 3% NaCl zone for aluminum (optimized for exterior trim durability), and a low-moisture fog zone for plastic (to prevent false degradation from excess humidity). An automotive OEM reported that this capability cut testing time for mixed-material assemblies by 60%, as they no longer needed to run three separate tests for one component.
Complementing its adaptive testing is the tester’s Cross-Material Analytics Platform, which aggregates data from each material zone to generate side-by-side performance comparisons. The platform uses machine learning to normalize corrosion metrics—converting metal rust rates (mg/cm²/day), plastic degradation (crack formation), and composite delamination (layer separation) into a universal “Corrosion Resistance Index (CRI)” score (1-100)—making it easy to identify weak points in mixed assemblies. For an aerospace manufacturer testing a wing leading edge made of titanium ribs and carbon fiber composite skins, the platform revealed that the composite performed better (CRI 92) than titanium (CRI 85) in coastal salt fog, prompting a design tweak to expand composite use. The platform also generates 2D heatmaps overlaying corrosion hotspots on the assembly’s CAD model, helping engineers visualize how material interactions (e.g., galvanic corrosion between steel and aluminum) impact overall durability. A consumer electronics brand used these heatmaps to address a issue with their smartphone frame: the analytics showed that the aluminum-chrome interface corroded 3x faster than either material alone, leading them to add a dielectric coating between the two.
Real-world applications highlight the tester’s versatility across mixed-material use cases: A luxury automotive brand used the MultiMatix Sync to test a convertible top frame combining steel, aluminum, and fiberglass, identifying that the fiberglass-to-steel bond was the corrosion weak point (CRI 68) and adjusting the adhesive to improve durability. An aerospace supplier validated a satellite component with titanium brackets and plastic insulation, using the zone-specific testing to ensure the plastic didn’t degrade in the high-salt environment needed to test titanium. A consumer electronics maker compared corrosion resistance of aluminum vs. magnesium smartphone chassis, using the CRI score to justify switching to magnesium (CRI 88 vs. aluminum’s 82) for a lighter, more durable design.
“The MultiMatix Sync solves a problem that’s only grown as materials innovation accelerates: how to test mixed assemblies as a single system, not a collection of parts,” said TOBO GROUP’s Material Science Director. “Manufacturers no longer have to guess how different materials will perform together—this tester lets them see, compare, and optimize, all in one run. It’s not just a testing tool; it’s a design enabler.”
