Core Product Competitive Advantages

1. Two configurable model variants for different‑throughput requirements KR‑508A six‑station setup allows running up to six specimens simultaneously, ideal for high‑volume batch‑testing laboratories. KR‑508B two‑station version occupies smaller footprint, well‑suited for occasional‑test workshops and small‑scale R‑D projects. Both variants strictly follow Japanese industrial‑standard rubbing kinematics.
2. Stable dead‑weight load‑application system Standard matched counter‑weights deliver constant vertical pressure without spring‑induced force‑drift during long‑duration cyclic rubbing. Friction‑hammer geometry and contact‑arc dimension fully match standard‑specified parameters, securing repeatable test‑results among replicate‑samples.
3. High‑capacity digital preset cycle counter Large‑range LCD counter supports 0‑999 999 cycle preset value. Equipment automatically stops once target rubbing repetitions are reached, eliminating manual stop‑watch counting mistakes for daily QC workflows.
4. Rapid‑lock multi‑purpose specimen‑clamping platform Robust metal test‑bench with quick‑release clamps holds leather, fabric and flexible sheet‑samples flat and wrinkle‑free. It prevents sample shifting during reciprocating friction movement and simplifies specimen‑swap‑over between test‑batches.
5. Solid integrated benchtop mechanical‑frame Heavy‑duty welded cabinet with anti‑vibration rubber feet suppresses operating vibration. Independent separated control‑panel simplifies parameter‑setting and status‑reading, lowering operator‑learning threshold for production‑floor quality‑control personnel.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation Place tester on stable horizontal lab‑bench, adjust anti‑vibration feet. Inspect reciprocating‑drive mechanism and counter‑weight hanging condition. Cut specimens and standard rubbing‑cotton cloth according‑to‑standard dimension. For wet‑rub test, pre‑moisten cotton cloth to specified moisture ratio. Power‑on unit and confirm LCD counter operates normally.
2. Specimen & Rubbing‑Cotton Mounting Secure test‑sample tightly onto bench‑clamps without folds or slack. Attach dry / pre‑wetted white cotton cloth onto friction‑hammer working‑surface. Hang corresponding standard counter‑weights to achieve required vertical test‑load.
3. Parameter Configuration Set target total rubbing‑cycle number via digital‑control panel. Double‑check frequency‑setting matches the selected model specification.
4. Execute Dry / Wet Rub‑Fastness Test Press start‑button. Friction‑hammer assembly performs continuous reciprocating rubbing under constant load. Machine automatically halts upon completing preset cycles.
5. Result Assessment & Record Remove used cotton rubbing‑cloth. Compare staining degree against grey‑scale card, document colour‑fastness rating. Also inspect test‑specimen surface for coating wear‑off. Multiple parallel‑specimen tests are recommended for statistically‑valid evaluation conclusion.
6. Post‑Test Tidying Discard consumed rubbing‑cotton. Clear fibre debris from test‑bench and friction‑hammer parts. Reset counter‑parameters for next‑batch‑testing. Periodically verify counter‑weight mass and mechanical‑linkage smoothness.

Safety‑Operation‑Reminder

Keep hands away from reciprocating friction‑hammer travel‑zone while equipment is running. Confirm specimen and cotton‑cloth are fully secured before initiating‑test‑cycle. Check counter‑weights are stably hung. Reliable equipment‑grounding must be completed before power‑on. Periodically inspect moving‑linkage‑fastening‑bolts.
