Finger simulation wear tester

Finger simulation wear tester

Applicable scope:

When human fingers, skin, teeth, and other media come into contact with various products, they will cause wear on their material surfaces, which seriously affects the quality of the products. This finger friction testing machine can simulate the process of almost all products and finger/skin wear, and can truly simulate liquid environments such as human sweat, hand moisturizer, sunscreen, cleaning agents, toothpaste, and other liquid media. This device can simulate the process of wear, including finger wear, nail scratches, tooth wear, sole wear, and industrial scratches.

Specific application areas include:

Car (exterior paint, interior parts)

Aviation and Shipbuilding Engineering (Interior, Instrument Testing)

Electronics industry (mobile phones, keyboards, touch screens)

Household/industrial appliances (exterior coating, armrest)

Paper industry (writing, printing, currency, safety paper, special paper, credit cards, passports, documents)

Medical equipment (dental coating, scale)

Printing industry

jewellery

Compliant with standards:

International standard IEC 68-2-70, German/European standard DIN EN 60068-2-70, BMW GS 97034/GS 97045, Daimler DBL 7384, Ford WSS-M2P188-A1, EWIMA Specification, Sony Ericsson 45/152 41-FEA 202 8139 Uen, etc

Working principle:

The main working principle of this device is to use a testing head, apply a certain amount of pressure, and carry a standard testing cloth to automatically cycle friction on the surface/coating of various materials at the specified angle according to the standard. Test conditions can be customized, including dry and liquid conditions (sweat, lotion).
