Laboratory Car Wash Simulation Tester
The Laboratory Car Wash Simulation Tester is a dedicated testing system designed for you to simulate automatic car wash tunnel conditions under controlled laboratory environments. By combining rotating brushes, programmable specimen movement, and spraying of cleaning media containing synthetic dirt, you can accurately evaluate the mechanical durability and surface appearance changes of automotive coatings, paint protection films, and plastic components after repeated wash cycles.
Application
You can use this tester for laboratory-scale simulation of automatic car wash processes, covering a wide range of automotive materials and surface systems, including:
(1) Wash-brush resistance testing of organic coatings used on complete vehicles and automotive components
(2) Scratch resistance and surface durability evaluation of automotive clear coats, base coats, and multi-layer coating systems
(3) Durability and appearance retention testing of paint protection films (PPF) under simulated car wash conditions
(4) Abrasion resistance testing of plastic exterior parts such as bumpers, trims, decorative strips, and covers
(5) Performance assessment of functional coatings applied to metal or plastic substrates
(6) R&D validation and quality control testing of surface materials exposed to simulated automatic car wash tunnel environments
