Product Overview

The KR‑445 specialised edge‑corner protector tester is purpose‑built for mechanical‑property assessment of paper corner guards, including L‑profile, U‑shaped, laminated and folded paper edge protectors. It reproduces real‑world stress conditions encountered during warehousing, stacking and logistics transit, to quantify compression resistance and bending‑failure performance of these packaging reinforcements.

Designed for packaging material manufacturers, logistics enterprises, in‑house quality‑control labs and accredited certification institutions, this bench‑top unit delivers repeatable measurement data. Test outcomes help reduce packaging breakage risks, optimise raw‑material formulation and verify compliance with BB/T 0023‑2004 and QB/T 1048 industry specifications.

Core Product Competitive Advantages

1. Dual‑Test‑Mode Mechanical Structure Supports both vertical compressive‑load testing and horizontal bending evaluation. One single machine completes two core performance assessments for paper corner samples, eliminating the need for separate pieces of test equipment. Precision‑machined flat platens guarantee high parallelism during sample loading.
2. High‑Accuracy Signal Acquisition System Equipped with high‑sensitivity load‑cell paired with 24‑bit high‑resolution AD conversion module. Force resolution reaches 0.01 N, ensuring stable and consistent readings even for low‑magnitude force changes across repeated batch‑sample runs.
3. Intuitive Touch‑Screen Human‑Machine Interface 7‑inch colour touch panel shows real‑time force‑vs‑deformation curves during testing. Operators configure test modes, travel speed and termination thresholds directly on‑screen. Built‑in thermal printer enables on‑site hard‑copy output of inspection results.
4. Comprehensive Data‑Export & Data‑Preservation Functions Multiple communication interfaces including USB and RS‑232 are provided for data transfer toward external PCs. Historical test datasets can be stored for later review and traceability. Power‑off memory function safeguards recorded data against unexpected power cuts.
5. Multi‑Layer Safety & Standard‑Compliant Design Built‑in electronic overload protection automatically halts drive motion when force exceeds instrument rated capacity. Test workflows fully align with BB/T 0023 and corresponding ISO requirements. Factory‑issued calibration documentation is supplied with each unit upon delivery.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation Position the tester on level workbench. Select matching fixtures, place paper‑corner sample centrally on the platen, adopt vertical or horizontal mounting according to your target test mode.
2. Parameter Configuration Power‑on the instrument, pick compression or bending test mode, set test velocity and termination conditions via touch‑screen panel.
3. Automatic Test Execution Initiate test run. The drive system applies load at preset speed. Real‑time force‑deformation curve is displayed on‑screen. Machine stops automatically once sample fails or preset cut‑off condition is reached.
4. Result Output & Archiving Review peak‑force and deformation data. Operators may print test reports directly on‑device or transmit datasets to computer via USB / RS‑232 for further sorting and filing.
5. Post‑Test Tidying Moving assembly returns to home‑position. Remove damaged specimen, wipe platens and fixture surfaces clean. Shut‑down equipment after finishing all sample batches.
