Product Overview

The KR‑205 floor‑standing PC‑controlled universal material tester adopts high‑stiffness double‑column gantry frame and Panasonic AC servo drive system. This versatile electromechanical test unit executes tensile, compression, bending, shear, peel, tear and two‑point extension assessments for metallic and non‑metallic specimens up to 50 kN force capacity. It delivers stable velocity regulation and high‑fidelity acquisition of force and displacement signals, supporting constant‑rate loading and constant‑rate displacement test modes.

Compatible with GB, ASTM, DIN, JIS and BS international test standards, this equipment is widely deployed for incoming‑goods inspection, new‑material formulation research and finished‑product reliability verification. Typical test samples cover rubber, elastomers, plastic profiles, wire‑and‑cable assemblies, safety‑belt webbing, composite fabrics, waterproof sheets, copper‑steel profiles, spring steel, bearing steel, stainless‑steel workpieces, castings, metal strips and non‑ferrous metal wire. It is commonly seen in polymer factories, metallurgical workshops, automotive component suppliers, university material‑science labs and third‑party accredited‑testing‑institutes.

Core Product Competitive Advantages

1. Reinforced Double‑Column Gantry Mechanical Frame Heavy‑duty alloy‑aluminum columns plus solid‑iron cross‑beam minimize frame deflection under intermediate‑high‑load conditions. The cross‑head supports jog fine‑tuning, fast‑slow speed switching and automatic high‑speed return after test completion. Multiple effective tensile‑stroke options are offered; custom‑widened test width and extended travel can be ordered for oversized specimens. Four leveling feet ensure stable installation on uneven lab floors.
2. High‑Precision Measurement & Data‑Acquisition Architecture High‑resolution photoelectric encoder captures displacement data. Embedded micro‑controller integrates measurement, closed‑loop control, arithmetic and local‑data‑storage functions. Load‑cell provides constant resolution of 1/200 000 full‑scale. An external contact‑type extensometer can be attached for precise elongation and elastic‑modulus calculation for high‑accuracy material‑characteristic evaluation. Two accuracy grades (Class 1 / Class 0.5) are selectable to satisfy different‑level lab metrology requirements.
3. Feature‑Rich Multilingual Windows Test Software Pre‑installed standard test templates match major global material‑testing specifications. Operators store custom‑material parameter profiles for repeated batch‑test execution. Fully‑editable report templates support native Excel export. Multiple real‑time plotting options include force‑displacement, force‑time, displacement‑time and stress‑strain graphs. Post‑test tools enable curve zoom‑in, overlay and comparative analysis. The program automatically computes tensile strength, upper/lower yield strength, non‑proportional extension strength, breaking elongation, elastic modulus, peel‑force statistics and total absorbed‑energy. Force‑and‑length measurement units are fully interchangeable: N, kg, lb, ton, mm, cm, inch. All datasets can be saved to local disk directories for later traceability review.
4. Multi‑Layer Hardware‑Software Safety Interlock Electronic upper‑and‑lower travel limit sensors prevent mechanical collision of moving cross‑head. When load exceeds 110 % of rated sensor capacity, automatic overload‑protection immediately halts movement to protect the precision load‑cell. Operators can toggle between manual‑triggered or automatic home‑return after finishing each test sequence.
5. Highly Expandable Fixture & Sensor Ecosystem Standard delivery includes baseline tensile‑grip assembly. A huge library of interchangeable optional jigs is available: wire‑wrapping clamps, metal tensile jaws, compression platens, 90°/180° peel fixtures, 3‑point /4‑point bending jigs, tear clamps and extensometer sets. Multiple interchangeable load‑cells can be fitted 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.
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. Install extensometer (if required) onto specimen gauge‑length zone.
3. Zero‑Calibration Procedure Perform force‑value and displacement 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.

The software description of computer servo-type universal testing machine

1. The function of standard modular is to provide users with the necessary applications to the test, covering GB, ASTM, DIN, JIS, BS, and other testing standard specifications.
2. Tested product information: provide users with the data to set about the products, one time to input and re-use permanently. To improve accuracy, the data can be corrected by the formula automatically.
3. Dual-Report Editor: provide users with the reported format that users choose (testing program add EXCEL reported format, Extend the previous single pattern of statements)
4. the data’s unit of length and force can be exchanged; a unit of force is T, Kg, N, KN, g, lb, and the unit of length in mm, cm, and inch.
5. Auto-optimization of graphic scale displays the best measurement of graphics. It can test the moving exchange in graphics. It has load displacement, load time, displacement time, stress-strain load -2 points extending maps, and many graphs compared.
6. Test results can be output in EXCEL format.
   G. testing results can be automatically preserved or manually preserved. After the test, it can automatically calculate the most strength, up and down yield strength, loop method, best method, non-proportional extended strength, tensile strength, compressive strength, tensile strength at any point, constant load extension, elastic modulus, rate of elongation, peel range of maximum force, minimum force, average force, total energy, bending modulus, x% load in break displacement, load X% in break displacement, and so on . the test data can be stored in any disk.
7. The software can output the previous data.
