Linear array abrasion tester ABREX®

Human fingertip abrasion & hand abrasion tester with true simulation With our 30-year experience and a full study of human physiology, it is concluded that a pneumatic actuation is the best and most efficient way to simulate human finger abarsion & hand abrasion. ABREX® is capable of translating the complex human fingertip and hand motions into a standardized testing machine. Compared with other systems which involve either linear drive, or gear system, only ABREX® can simulate the human fingertip and hand movement. General abrasion is a common mechanical process on surfaces caused by scuffing, rubbing, or scratching under normal operation or under environmental exposure. Additionally, there is a special abrasion which is generated merely between human fingertip & hand and touched product surface. This special abrasion, namely ABREX®-ABRASION leads to distinct patterns of damages on the materials and its surfaces. It widely appears in many types of consumer products. ABREX® -ABRASION, is a soft-chemo-mechanical fingertip abrasion & hand abrasion and 99% simulation of the reality with the same wear pattern. It is a highly complex abrasion process which involves: Firstly a 45° angle impact driven by a dynamic pneumatic cylinder attached with a viscoelastic fingertip under a defined load; Then a friction rubbing or tumbling motion between the sample and a textile containing dirt, dandruff, oil, sweat or various types of testing liquids; Followed by a retraction movement with or without the contact at the surface depending on the application.
