In the contemporary industrial ecosystem, the durability of materials against atmospheric corrosion is not just a quality metric—it is a critical safety and longevity requirement. As a premier OEM Salt Spray Machine Manufacturer, Dongguan Huanyi Instruments is at the forefront of providing simulated accelerated corrosion environments that mimic decades of exposure in a matter of weeks. The global market for salt spray (fog) testing is experiencing a paradigm shift, driven by the rapid expansion of the Electric Vehicle (EV) industry, aerospace advancements, and marine infrastructure development.
From the coastal humidity of Southeast Asia to the industrial chemical exposures in Central Europe, the demand for high-precision salt spray chambers is surging. Modern manufacturers are no longer satisfied with basic "pass/fail" results; they require cyclic corrosion testing (CCT) that integrates humidity, drying, and temperature fluctuations to reflect real-world localized application scenarios.
With the rise of EVs, battery casings and electronic control units (ECUs) must withstand rigorous salt mist tests to ensure zero-fail reliability in winter-salted road conditions.
ISO 9227VDA 621-415High-altitude components face extreme thermal cycles. Our OEM solutions provide combined TVAC and salt spray environments for comprehensive component validation.
MIL-STD-810HASTM B117Simulating offshore environments requires high-concentration salt fog and persistent high humidity, testing the limits of specialized marine coatings.
NSS/CASS TestsCorrosion RatesDongguan Huanyi Instruments Technology Co., Ltd. was established on March 20, 2007, covering an area of 6,022 square meters. As a high-tech enterprise integrating R&D, production, and sales, we have reached a milestone where our expertise is sought by national regulatory bodies. We participated in the drafting of national standards and industry standards for environmental simulation test equipment, a testament to our profound professional knowledge and authority in the field.
Our philosophy is "customer-centric, quality-guaranteed, honesty-based, and innovation-oriented". Through unremitting efforts, Huanyi has cultivated a high-quality team with rich production, R&D and management experience.
The future of salt spray machine manufacturing lies in the fusion of Digital Twins and AI-driven Predictive Analytics. Huanyi is currently developing next-generation testing units that don't just record data but analyze the morphology of corrosion in real-time through high-definition visual sensors.
Implementation of IoT-based remote monitoring systems, allowing engineers to manage tests from any global location with millisecond accuracy in salt concentration control.
Developing closed-loop salt solution recycling systems to reduce environmental impact and lower operational costs for large-scale industrial labs.
AI algorithms to predict the "Time-to-Failure" based on early-stage microscopic corrosion patterns, significantly shortening R&D cycles.
High Quality Control from every aspect of raw material, production, installation, and commission. We use internationally renowned brand components to ensure performance stability.
With more than 20 years of experience, we have professional production and R&D personnel. We use an ERP system to monitor the production process, ensuring timely delivery.
Modern equipment including laser cutting panels, automated production lines, and ERP control systems help us reduce waste and maximize precision.
Our products have been selling to Southeast Asia, Europe, the United States, and the Middle East, receiving exceptional feedback from over 2,500 customers.
The company has strong independent innovation capabilities. In recent years, it has fully realized product upgrades and launched new domestically advanced test instruments, which have been widely praised by users at home and abroad. Our 2016 establishment of the Digital Sheet Metal Center and our ISO9001:2015 certification underscore our commitment to excellence.
For large-scale manufacturers, we don't just sell a salt spray machine; we design integrated laboratory ecosystems. This includes the integration of Temperature/Humidity/Vibration systems (as seen in our product line) with salt spray modules, providing a holistic stress-test environment that matches the complexity of modern engineering.
NSS (Neutral Salt Spray) uses a pH-neutral solution for metals and alloys. AASS (Acetic Acid Salt Spray) and CASS (Copper Accelerated Acetic Acid Salt Spray) add acidity and copper chloride to accelerate the corrosion process, typically for decorative coatings like chrome plating.
We utilize precision-engineered quartz nozzles and a heated saturation barrel system. The internal geometry of our chambers is designed to prevent salt droplets from falling directly onto the samples, ensuring a consistent mist distribution according to ASTM B117.
Yes. Our Digital Sheet Metal Center allows us to manufacture bespoke chambers ranging from compact 100L benchtop models to walk-in chambers exceeding 20 cubic meters for entire vehicle testing.
