Product Overview

The KR‑416 pendulum‑style puncture‑resistance tester measures dynamic puncture‑resistant performance for corrugated fibre‑board and solid paper‑board. Based on pendulum potential‑energy conversion principle, a standard triangular‑pyramid piercing head strikes and penetrates fixed board specimen. The system calculates total energy consumed during piercing, tearing and bending deformation, with final results displayed in Joules (J).

This bench‑top lab device complies strictly with ISO 3036 and GB/T 2679.7‑2005 standards. It evaluates the ability of carton‑board to resist sharp‑object impact during logistics handling and transit. Widely deployed by corrugated‑carton factories, paper‑board manufacturers, packaging‑R&D centres and accredited third‑party testing laboratories for incoming‑raw‑material inspection and finished‑packaging quality assessment.

Core Product Competitive Advantages

1. Multi‑Range Four‑Gear Measuring System, Broad Test Coverage Four‑switchable measuring gears cover the full 1‑48 J testing scope. Each gear maintains tight tolerance within the valid 20‑80 % upper‑limit reading interval, delivering accurate readings for both light‑weight thin board and heavy‑duty thick corrugated‑board samples.
2. Robust Pendulum Mechanical Assembly with Low Friction Loss Precision‑machined pendulum‑shaft structure minimises pointer friction and shaft‑rotational resistance. Long free‑swing cycle guarantees minimal energy loss caused by mechanical friction and air drag, securing authentic and repeatable puncture‑energy test outcomes. The standard triangular‑pyramid piercing head fully matches ISO‑specified dimensional requirements.
3. Fast‑Clamping Specimen Fixture & Automatic‑Reset Handle Spring‑loaded upper‑lower clamping platens achieve rapid and firm specimen fixing to prevent sample slippage upon impact. The operating handle features automatic‑return mechanism after pendulum release, streamlining repeated batch‑specimen operations and lowering manual‑operation workload for QC‑lab staff.
4. Micro‑Computer Control with Built‑In Statistical & Print Functions LCD graphic display shows real‑time puncture‑energy values. On‑board processor automatically computes maximum, minimum and average values from multi‑sample groups. Integrated thermal printer outputs hard‑copy inspection reports directly on‑site without external auxiliary equipment.
5. Safe Open‑Structure Cabinet‑Type Layout Open‑frame mechanical layout allows easy visual inspection and component maintenance. Multiple built‑in safety interlock features prevent accidental pendulum release. Adjustable levelling feet stabilise the whole machine to counteract table‑surface unevenness and isolate external vibration interference.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation Place instrument on vibration‑free horizontal laboratory bench, adjust levelling feet for level status. Power‑on and complete system self‑check. Cut board specimens to standard dimensions and condition them under standard temperature‑humidity environment. Select suitable measuring gear according to expected puncture‑energy magnitude.
2. Specimen Mounting Open the spring‑actuated clamping platens, lay flat the corrugated‑board sample. Lock platens tightly to hold specimen firmly and eliminate any slack which may shift under pendulum impact.
3. Pendulum Release & Puncture Test Lift and lock pendulum to initial standby position. Trigger release handle. The pendulum swings downwards; standard pyramid‑head pierces, tears and bends through paper‑board specimen. Remaining swing energy is captured by the measuring mechanism.
4. Data Reading & Batch Statistics Read puncture‑strength energy value from LCD screen. Conduct repeated tests for multiple parallel specimens. Review auto‑calculated batch‑average and deviation statistics. Print inspection‑report via built‑in thermal printer if needed.
5. Post‑Test Tidying Pendulum handle automatically returns to home‑position. Remove pierced sample fragments. Clear debris from clamping‑platen zone. Shut‑down main power‑supply after finishing all test batches. Perform periodic pendulum‑system calibration.
