Product Overview
The KR‑2902A multi‑mode abrasion resistance tester is multi‑purpose surface‑wear laboratory apparatus. It integrates three mainstream abrasion evaluation workflows: alcohol‑cotton rubbing test, eraser abrasion test and pencil scratch hardness test. Under defined vertical load, the friction head performs controlled reciprocating rubbing cycles on specimen surfaces. It assesses anti‑wear performance of screen‑printed patterns, spray‑paint layers and decorative coatings for consumer‑electronic components.
Typical test samples include TV remote‑control buttons, mobile‑phone housings, ear‑shell parts, keyboard keycaps, battery casings, wire‑marking prints, leather and plastic decorative pieces. Dual‑station parallel‑testing design improves lab‑testing efficiency for incoming‑material QC, new‑coating formulation validation and finished‑product batch inspection.
Core Product Competitive Advantages
- Dual‑station parallel‑testing architecture
Two independent test stations operate simultaneously. Users can run identical or different abrasion‑mode tests on two separate specimens at one time, effectively shortening batch‑sample inspection cycle.
- Broad adjustable load, stroke and speed range
Configurable test load spans 50‑1000 g; reciprocating stroke is manually tunable from 10‑60 mm. Rubbing speed is stepless‑adjustable within 5‑60 cycles per minute via control knob. It satisfies diverse coating‑product‑test‑condition requirements.
- Preset cycle counter with power‑off memory
High‑capacity counter supports preset value up to 99 999 999 cycles. It retains set parameters and accumulated test‑data after power‑loss, eliminating repeated parameter‑input work for continuous‑testing tasks. Real‑time LCD read‑out shows running speed and completed cycles intuitively.
- Complete interchangeable fixture‑kit for three test modes
Full‑set swap‑over jigs are supplied: alcohol‑cotton rubbing fixtures, eraser abrasion fixtures and pencil‑hardness test fixtures. Standard consumables include cotton cloth, eraser and 2B pencils. Quick fixture swap enables fast switching between different test‑procedures.
- Robust anti‑corrosion cabinet construction
Machine cabinet adopts electrostatic baking‑paint finish. Working platform and fixture‑mounting parts are sand‑blasted aluminium alloy, featuring corrosion‑resistance and structural rigidity. Stable mechanical transmission ensures smooth reciprocating motion and consistent test‑reproducibility for long‑term continuous operation.

Standard Complete Test Operating Workflow
- Pre‑Test Preparation
Place tester on level stable lab‑bench. Check reciprocating‑transmission and fixture‑locking condition. Select target abrasion‑mode and install corresponding fixture assembly. Assemble required counter‑weights according to test‑spec. Power‑on unit and confirm LCD display works normally. Prepare finished test‑specimens.
- Specimen Mounting
Secure test‑piece firmly on the work‑platform. Adjust stroke‑travel and friction‑head height, to make rubbing medium fully contact specimen coating‑surface without excessive compression.
- Parameter Configuration
Set target rubbing‑speed and preset termination‑cycle number on control panel. Verify power‑off‑memory function status.
- Launch Reciprocating Abrasion Test
Press start‑key; friction‑head carries out automatic back‑and‑forth rubbing under configured load. System accumulates completed‑cycle count. Equipment auto‑halts upon reaching preset cycles.
- Result Observation & Record
Take‑off specimen, inspect coating / printing‑layer for fading, peeling‑off or exposing base‑material. Document abrasion status for quality‑report filing. Multiple parallel‑specimen tests are recommended for statistically‑valid conclusion. Switch fixtures if you need to run other abrasion‑modes.
- Post‑Test Tidying
Remove tested sample and used consumables (cotton cloth / eraser / pencil). Clean platform and fixture surface of debris. Reset counter‑parameters for next‑batch testing. Periodically inspect transmission‑parts and weight‑pieces.
