In the modern industrial landscape, corrosion is more than a maintenance nuisance—it is a trillion-dollar challenge. According to the World Corrosion Organization, the global cost of corrosion is estimated at $2.5 trillion USD, or roughly 3.4% of the global GDP. For industries spanning from automotive to aerospace and offshore energy, the ability to predict and mitigate corrosive failure is paramount.
As a leading OEM Salt Spray Corrosion Chamber Supplier, Dongguan Huanyi Instruments Technology provides the critical infrastructure needed to validate material integrity. Our chambers are engineered to simulate years of harsh coastal and industrial atmospheric exposure in a matter of days, providing manufacturers with the data necessary to innovate with confidence.
The transition toward Electric Vehicles (EVs) and renewable energy infrastructure has shifted demand toward Cyclic Corrosion Testing (CCT). Unlike traditional continuous salt spray, CCT mimics real-world conditions by cycling through salt fog, drying, and humidity phases.
Our factory provides end-to-end OEM/ODM services, allowing global brands to customize chamber dimensions, salt concentration control systems, and data logging interfaces to meet specific ASTM B117, ISO 9227, or JIS Z 2371 standards.
Based in Dongguan, the "World's Factory," we leverage a mature ecosystem of precision sheet metal, advanced sensors, and automation components to deliver high-quality instruments with 30% faster lead times than Western competitors.
The future of salt spray testing lies in digitalization and precision. Huanyi Instruments is currently developing the next generation of Smart Corrosion Chambers which feature:
Testing EV battery enclosures and undercarriage components against winter de-icing salts. Essential for the safety of high-voltage systems.
Validating the lifespan of navigation systems and sensors exposed to high-salinity maritime environments.
Assessing the durability of powder coatings, anodized aluminum, and galvanized steel used in coastal architecture.
Our Dongguan Huanyi Instruments factory operates with a vertically integrated model. By maintaining a Digital Sheet Metal Center and an in-house R&D team, we eliminate the delays common in outsourced manufacturing. Our use of ERP systems ensures that from the moment of "Quality Control" in raw materials to the final "After-Sales Service," every step is documented and optimized for speed and reliability.
Dongguan Huanyi Instruments Technology Co., Ltd. - A High-Tech Enterprise
Established on March 20, 2007, Huanyi has grown into a powerhouse of environmental simulation. Our philosophy is "customer-centric, quality-guaranteed, honesty-based, and innovation-oriented". We don't just build chambers; we help draft national and industry standards (such as GB5364 and GBT50325), positioning us as a leader in the Chinese and global testing equipment market.
Company established in Dongguan, specializing in environmental test instruments.
Expansion of reach with Xi'an and Chongqing offices to support inland manufacturing.
Establishment of the Digital Sheet Metal Center, enabling precision OEM customization.
Launch of Guangdong Huance Testing Technology Co., Ltd. – a dedicated laboratory for material validation.
High Quality Control from every aspect of raw material, production, installation, and commission. ISO 9001:2015 certified processes.
With more than 20 years of experience, our R&D personnel ensure that Huanyi meets large-volume production orders with ERP precision.
Modern equipment including laser cutting, automation, and ERP-driven systems to reduce waste and ensure 100% compliance.
While both specify salt spray testing parameters, ISO 9227 includes AASS and CASS tests for decorative coatings, whereas ASTM B117 is the primary standard for continuous neutral salt spray (NSS) used in the USA.
We use a dual-jacketed heating system and high-precision sensors to ensure temperature variance is kept within ±0.5°C, critical for repeatable results.
Yes, our premium OEM models are equipped with automatic cycling controls that transition between salt fog, dry heat, and 98% relative humidity phases.
We provide remote calibration support, modular spare parts that are internationally available (Schneider, Omron components), and full English technical documentation.
