Product Overview

The KR‑401 BCT carton compression‑strength analyser is dedicated laboratory equipment for evaluating load‑bearing and stacking‑performance of corrugated shipping containers and various packaging boxes. It utilises precision load‑cell sensing and servo‑driven loading architecture to replicate real‑world vertical stacking stress during warehouse storage and cargo transit. The unit captures peak collapse‑load, compression deformation and full force‑displacement curve, delivering objective BCT (Box Compression Test) data as critical reference for carton structural optimisation and safe stacking‑height calculation.

Two variants are available: standard computer‑controlled KR‑401 and touch‑screen upgraded KR‑401B. This test rig complies with GB/T 4857.4, GB/T 4857.16, ISO 2872, ASTM‑D642, GB/T 16491, TAPPI‑T804 and JIS‑Z0212. Widely adopted by carton‑manufacturing plants, consumer‑goods factories, packaging‑R&D institutions and accredited third‑party QC laboratories for finished‑container validation and incoming‑packaging assessment.

Core Product Competitive Advantages

1. Robust Gantry‑Style Frame & High‑Efficiency Transmission System Extruded‑aluminium alloy frame finished with durable paint coating. Adopts zero‑clearance double‑precision ball‑screw drive mechanism. Low‑friction motion guarantees outstanding structural rigidity under heavy‑load conditions, minimising frame deflection throughout long‑duration compression and stacking‑hold tests.
2. High‑Performance Servo‑Motor Closed‑Loop Control High‑precision AC servo‑motor with digital driver enables stepless adjustable test‑speed ranging from 12 mm/min up to 350 mm/min. Speed‑control accuracy holds within ±0.2 %. Low‑noise stable drive adapts to diverse international‑standard test‑velocity requirements.
3. High‑Resolution Multi‑Unit Force‑Measurement System Load‑cell delivers 1/50000 resolution with ±1 % full‑scale accuracy. Supports quick unit‑switching: N, kN, kgf, lbf, kPa, MPa. Multiple‑capacity selections: 500 kg, 1 ton, 2 ton, 5 ton, to match light‑weight colour‑boxes through heavy‑duty large‑size shipping cartons.
4. Powerful Data‑Acquisition & Analysis Software Suite Connects with industrial PC for full‑featured test management. Operators configure test parameters, monitor real‑time force‑deformation curves, store historical batches, compute statistical values and export formatted test‑reports. Supports data‑export for further office‑software processing. Touch‑screen standalone version (KR‑401B) is available for PC‑free workflow.
5. Multi‑Layer Integrated Safety‑Protection Mechanism Equipped with leakage‑current protection, overload auto‑stop function and upper‑lower travel‑limit interlock. Emergency‑stop button is readily accessible. These safety features protect sensor, mechanical assembly and operators during heavy‑load destructive‑testing cycles.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation Place machine on level rigid factory floor. Secure ground connection. Power‑on equipment and PC‑software system. Inspect platen parallelism and mechanical travel range. Condition carton specimens under standard temperature‑humidity environment. Select suitable force‑capacity and configure test‑speed / stop‑conditions in software interface.
2. Specimen Placement Position conditioned carton sample centrally on lower platen. Ensure top‑and‑bottom faces keep full flat contact with platens; avoid eccentric offset which would generate false test‑readings.
3. Start Compression‑Strength / Stacking‑Hold Test Trigger test‑run command. Servo‑system drives upper platen downwards at set constant velocity. System continuously records load‑force and displacement data. For destructive‑BCT test, machine auto‑captures peak‑crush‑load at carton collapse. For stacking‑simulation test, system maintains preset constant‑pressure for defined holding duration. Press emergency‑stop button if abnormal situation occurs.
4. Data Review & Report Export After test completion, review force‑deformation curve, maximum‑load and deformation‑value on software interface. Batch‑test data can be saved locally, statistically processed and exported or printed for lab‑archiving and product‑certification documentation.
5. Post‑Test Tidying Platen automatically returns to home‑position. Remove deformed carton specimen. Clear debris from platen surfaces. Shut‑down software and main power‑supply after finishing all test batches. Perform periodic load‑cell calibration.
