Environmental Testing Solutions for Global Industries

Danble designs and manufactures advanced environmental test chambers for automotive, battery, electronics, aerospace, solar and industrial manufacturers to validate product reliability under extreme conditions.

High-Temperature Stability Testing for Lithium-Ion Battery Packs.
Application: A energy storage company required validation of lithium-ion battery performance under extreme conditions.

Testing Protocol:
​Temp Cycling: -20°C to +70°C (10 cycles) to simulate day-night fluctuations.
​Humidity Control: 30–90% RH to mimic arid environments.
​Cycle Life Assessment: 2,000+ charge-discharge cycles under thermal stress.

Key Results:
​Capacity Retention: 92% after 2,000 cycles at +50°C.
​Safety : No thermal runaway events detected via built-in thermal imaging.
​Benefit: Extended warranty period from 1 to 3 years for long-term deployments.

Humidity & Thermal Stress Testing for EV Charging Infrastructure
Application: A EV charger manufacturer sought to enhance resistance of charging ports.

Test Protocal:
Salt Spray Test: 5% NaCi mist at +35℃ for 2,000hours
Temperature Cycling: -10℃ to +55 ℃ with 95%RH
Electrical Safey: Arc flash detection under humidity stress

Key Results:
Corrosion Resistance: 0% rust formation on treated connectors.
IP Rating: Maintained IP67 standards post-testing.
Client Benefit: Reduced warranty claims by 55% in humid regions.

Background: A 3C manufacturer developed industrial LCD monitors for outdoor surveillance systems in tropical cliamtes ( 85℃/85% RH continuour exposure)

Solution:
Danble Instruments deployed its Constant Thermo-humidity Chamber, features:
Environmental Simulation: 85℃±2℃， 85%RH±5%， 1000hrs accelerated aging.
Visual Inspection: Mura dectection & warpage measurement.
Electrical Validation: Monitor piexl response time and color accuracy post-test

Key Results:
Zero Mura Defects: Achieved 98% uniformity across 1000h testing.
Warpage ＜ 0.05mm: Polarizer modules optimization reduced stress concentration
MTBF Improvement: Field data showed 40% reduction in warranty claims.

Background: A semi-conductor manufacturer faced recurring failures in IC chips during high-altitude deployment.

Solution:
Danble Instruments deployed its Dual-Zone Thermo-Humidity Chamber, featuring:
Temperature Range: -70℃ to + 150℃ with ±0.5℃ stability.
Humidity Control: 10-98% RH at 25 ℃,rapid humidity cycling(≤5% RH/min)
