Product Overview

The KR‑204B high‑precision electromechanical universal testing instrument adopts a rigid double‑column gantry framework, built for room‑temperature mechanical property evaluation of metal specimens as well as highly‑deformable non‑metallic samples such as rubber, polymer, and leather. Supported by dedicated Windows analysis software and an optional large‑deformation extensometer, this unit executes tensile, tear, peel and adhesion‑strength assessments.

Following GB/T 16491‑1996 and other global testing specifications (ISO, ASTM, DIN, JIS), the system delivers consistent measurement of force and displacement under constant‑velocity loading or constant‑velocity displacement modes. Suited for incoming‑batch QC, new‑product validation and laboratory research work, it is widely deployed across metallurgical workshops, polymer manufacturing plants, cable factories, higher‑education institutes and third‑party inspection‑arbitration laboratories.

Core Product Competitive Advantages

1. Robust Double‑Column Mechanical Framework Heavy‑duty welded gantry structure suppresses frame deflection during loading. Movable cross‑head supports jog fine‑adjustment, fast‑slow speed switching and automatic home‑return upon test completion. Multiple tensile‑stroke options (800 mm / 1000 mm / 1200 mm) are offered; test width can be widened on request to accommodate over‑size test pieces. Sturdy leveling feet secure stable placement on uneven lab floors.
2. High‑Resolution Measurement & Acquisition Architecture High‑precision photoelectric encoder captures displacement values. Embedded microcontroller integrates measurement, closed‑loop control, arithmetic and local‑data‑storage functions. Load‑cell supplies constant resolution up to 1/200 000 full‑scale. Two accuracy grades (Class 0.5 / Class 1) are selectable. The optional large‑deformation extensometer precisely records elongation data for high‑stretch flexible materials, eliminating measurement deviation caused by frame elastic deformation.
3. Multifunctional Windows‑Based Test Software Pre‑configured test templates match mainstream international material‑testing standards. Operators may store custom material‑parameter profiles for repeated batch‑test execution. Report layouts are fully editable with native Excel export capability. Multiple real‑time graph types are generated: force‑displacement, force‑time, stress‑strain and elongation‑time curves. Post‑test functions include curve zoom‑in, overlay and comparative analysis. The software auto‑computes tensile strength, upper/lower yield strength, breaking elongation, elastic modulus, peel‑force statistics and many other critical indexes. Force‑and‑length measurement units are freely interchangeable (N, kg, lb, ton, mm, cm, inch). All datasets can be saved locally for traceability review.
4. Complete Multi‑Level Safety Mechanism Electronic upper‑lower travel limit sensors prevent cross‑head mechanical collision. When load exceeds 110 % of rated sensor capacity, automatic overload‑protection instantly halts movement to safeguard the precision load‑cell. Physical emergency‑stop button sits on the front console for rapid manual intervention in unexpected conditions. Users can toggle between manual‑triggered or automatic high‑speed home‑return after finishing each test run.
5. Expandable Fixture Compatibility Standard delivery includes universal tensile‑grip assembly. A full portfolio of interchangeable optional jigs can be added: metal tensile jaws, peel fixtures, tear clamps, compression platens and extensometer kits. Multiple interchangeable load‑cells are supported to broaden effective measuring scope for mixed‑load sample batches.

Standard Complete Test Operating Workflow

1. Pre‑Test Inspection & Parameter Setup Power‑on main unit and supporting desktop computer; launch dedicated test software. Select or create test procedure matching target‑material standard, configure termination thresholds and report‑template settings. Mount extensometer (if required for elongation measurement).
2. Specimen Mounting & Axial Alignment Use jog‑mode to adjust cross‑head position; firmly fasten test‑piece inside corresponding fixture and ensure good coaxial alignment to eliminate eccentric‑loading impact.
3. Zero‑Calibration Procedure Perform force‑value, displacement and extensometer zero‑reset to eliminate initial mechanical offset before formal loading starts.
4. Automatic Test Execution Trigger test start command. Servo‑driven cross‑head travels at preset velocity; system continuously captures force, displacement and deformation data while rendering real‑time test curves.
5. Post‑Test Data Analysis & Report Export Test automatically terminates on specimen fracture or upon reaching preset stop criteria. Review key characteristic‑point data, zoom and overlay curves; export datasets to Excel or print formal inspection reports.
6. Equipment Shutdown Steps Cross‑head returns to home position; remove tested specimen and wipe fixture surfaces clean. Close software application and cut off main power supply.
