Thermal shock testing is not merely about heating and cooling; it is about simulating the violent transition of material expansion and contraction. At Dongguan Huanyi Instruments Technology Co., Ltd., we specialize in high-velocity temperature transitions that expose latent defects in solder joints, hermetic seals, and composite material bonding. Our custom machines are designed to meet the rigorous demands of MIL-STD-883 and IEC 60068 standards.
Unlike off-the-shelf units, our custom solutions address the "Coefficient of Thermal Expansion (CTE)" mismatch specific to your DUT (Device Under Test). We integrate advanced airflow dynamics and liquid-to-liquid transfer mechanisms that ensure temperature recovery times of less than 5 minutes, providing the high-fidelity data required for modern failure mode analysis (FMEA).
Testing Power Electronics and Battery Management Systems (BMS) for sudden environmental shifts during fast charging or extreme climate operation. Our chambers help EV manufacturers ensure 15+ years of operational life.
Base station components endure relentless outdoor cycles. Our thermal shock chambers simulate decades of weathering in weeks, focusing on the integrity of signal processing PCBAs.
In vacuum and sub-orbital environments, temperature transitions are instantaneous. Huanyi provides specialized low-pressure integrated thermal shock solutions for satellite components.
Established on March 20, 2007, Dongguan Huanyi Instruments Technology Co., Ltd. has evolved into a global titan of environmental simulation. As a high-tech enterprise, we didn't just follow standards—we drafted them. Our participation in national and industry standard drafting positions us at the vanguard of the testing instrument industry.
Our philosophy: "Customer-centric, Quality-guaranteed, Honesty-based, and Innovation-oriented."
Leading the shift from reactive testing to predictive reliability.
Focus on basic hot/cold air transfer. Traditional PID control. (Huanyi Legacy 2007-2015)
IoT-enabled monitoring, ERP synchronization, and automated DUT power cycling. (Current Standard)
Digital Twin integration where the chamber predicts failure points before the cycle finishes. (In R&D for 2025+)
High Quality Control from every aspect of raw material, production, installation, and commission. We utilize internationally renowned brand components to ensure longevity.
With more than 20 years of experience, we meet large-volume production orders using ERP systems to monitor every phase, ensuring 100% timely delivery.
Our facility features laser cutting for panels, automated digital sheet metal processing, and ISO 9001:2015 certified workflows to reduce waste and carbon footprint.
