This series of machines is suitable for the wear resistance test of keys, plastic casings, and coating surfaces. That is, apply the specified load and rub alcohol on the surface of the test piece back and forth. After reaching the set test times, check if there are obvious wear marks, such as the wear of the coating on the mobile phone casing and the printed characters on the surface.
The maximum load capacity is 7.5kg
The reciprocating stroke for wiping is 50mm
The test speed range is adjustable from 10 to 120 times per minute
Two samples each with load capacities of 100g, 200g, 300g and 500g
The machine dimensions are 600×450×300mm
The net weight of the machine is 38 kilograms
