Shanghai Huanjing Test Equipment Factory was contracted by an aerospace organization to conduct a constant temperature and humidity test for an aerospace engine. The existing process required a topcoat drying time of 7 days, which significantly delayed production and shipping schedules. To address this issue, the factory customized a high-low temperature alternating heat and humidity test chamber with precise control parameters.
The equipment selected was the HS-800B model, featuring a temperature range of 0°C to 100°C and a humidity range of 30% to 98% RH. Its internal dimensions are 800×1000×1000 mm, making it suitable for testing large components like engine parts. After initial testing, it was confirmed that the temperature and humidity ranges were well within the required specifications for the aerospace engine.
However, after running the test for three days, it became clear that the current topcoat was not performing as expected under these conditions. This led to delays and inefficiencies in the production line. With guidance from our technical team, the metallurgy department of the aerospace organization collaborated with the coating supplier to introduce a new topcoat solution.
A new primer and topcoat were applied, followed by a series of rigorous tests, including a water-soluble humidity test, adhesion test, solvent resistance test, and scratch test. The results were highly satisfactory, proving that the HS-800B test chamber could effectively simulate real-world conditions and support the development of more durable and reliable aerospace coatings.
This case highlights the importance of custom-built environmental testing solutions in the aerospace industry, where precision and reliability are critical. Shanghai Huanjing Test Equipment Factory continues to provide tailored testing systems to meet the demanding standards of aerospace applications.
