Product Overview

The KR‑204D integrated environmental‑simulation universal testing unit combines a heavy‑duty double‑column servo‑driven test frame with a slide‑out temperature‑controlled cabinet. This all‑in‑one solution evaluates mechanical performance of materials under extreme hot‑and‑cold operating conditions. Users can slide the whole chamber away to carry out regular ambient‑temperature tensile, compression, bending, peel, tear, shear and fatigue tests without extra equipment modification.

Supporting a broad temperature spectrum, the system reproduces real‑world service environments for rubber, polymer films, foam, leather, wire‑cable materials, textiles, non‑woven fabrics and light‑metal specimens. Fully compliant with GB, ISO, ASTM, DIN and JIS global testing specifications, this machine is widely deployed in automotive‑material R&D labs, new‑energy component factories, polymer modification workshops and accredited third‑party test institutes.

Core Product Competitive Advantages

1. Slide‑Out Removable Environmental Cabinet The temperature chamber runs on heavy‑duty linear guide rails, enabling full horizontal withdrawal in seconds. Operators can swiftly access specimens or switch over to room‑temperature testing workflows. Inner cavity is constructed from corrosion‑resistant SUS304 stainless steel, fitted with double‑layer insulated observation window for real‑time visual inspection of sample deformation during testing. Well‑sealed door structure minimizes cold‑heat leakage to stabilize internal temperature field.
2. Precise PID Air‑Circulation Temperature Control System Adopts forced hot‑cold air convection circulation plus self‑tuning PID algorithm. Internal cavity temperature uniformity reaches ±1 ℃. Multiple configurable temperature ranges are available including ‑40 ℃~+150 ℃ and extended‑range ‑70 ℃~+150 ℃. Built‑in multi‑level safety interlocks cover overheat protection, compressor overload alarm and door‑open safety cut‑off to prevent hardware damage during abnormal operation.
3. High‑Stability Servo‑Mechanical Test Frame Equipped high‑performance AC servo motor paired with precision ground ball‑screw transmission. Test speed is adjustable from 0.05‑250 mm/min with tight speed tolerance. 0.5‑grade high‑precision interchangeable load‑cell options cover 1 kN‑300 kN capacity range, offering constant force resolution up to 1/250 000 full‑scale to capture subtle force changes of flexible and brittle test samples.
4. Powerful Multilingual Windows‑Based Test Software Pre‑configured test templates match major international material‑testing standards. Operators may edit and save custom test workflows, termination thresholds and report layouts. Multiple real‑time plotting functions render force‑displacement, stress‑strain and force‑time curves simultaneously. After each test run, the software auto‑calculates tensile strength, yield value, breaking elongation, compression modulus, peel‑force statistics and other critical indicators. Test datasets and graphs support local storage, overlay comparison, Excel export and A4‑format report printing. Multi‑level user‑permission management prevents unintended parameter alteration.
5. Rich Expandable Fixture Ecosystem Standard supply includes baseline tensile‑grip assembly. A comprehensive selection of optional attachments can be fitted inside the temperature cavity: compression platens, 3‑point /4‑point bending jigs, tear clamps, peel fixtures and high‑temperature compatible extensometer assemblies. Internal usable test width can be widened on request to accommodate oversized sheet‑shaped work‑pieces.
6. Multi‑Layer Hardware‑Software Safety Architecture Electronic upper‑lower travel limit sensors plus mechanical hard stops block cross‑head over‑travel impact. 110 % overload protection automatically halts movement to safeguard load‑cell. Emergency‑stop button is accessible on the machine console. Chamber heating/cooling function will suspend once the cabinet door is opened to protect operators from frost‑burn or scald hazards.

Standard Complete Test Operating Workflow

1. Equipment Inspection & Parameter Setup Check hydraulic‑free servo frame condition, chamber sealing status and interlock function. Launch dedicated test software; configure target temperature, holding‑soaking duration, test velocity and termination criteria, save custom recipe for batch‑repeated testing.
2. Chamber Pre‑Conditioning Close chamber door, activate heating or refrigeration cycle, wait until internal cavity temperature stabilizes fully before specimen loading.
3. Specimen Mounting & Thermal Soaking Slide out the environmental cabinet, secure test sample into corresponding fixture assembly, push cabinet back into locked position. Maintain preset temperature for required soaking period so the whole specimen reaches target test temperature.
4. Automatic Mechanical Test Execution Initiate test run. Servo‑driven cross‑head travels at predefined speed to finish tensile / compression / bending / peel assessment; system continuously logs force, displacement and deformation signals while generating real‑time test curves.
5. Post‑Test Data Review & Report Export Upon specimen fracture or meeting stop conditions, testing terminates automatically. Analyze characteristic‑point data, overlay multiple groups of curves for comparative study, export editable datasets and formal inspection reports.
6. Post‑Test Shutdown Process Stop temperature control program; wait for chamber interior to cool down to near ambient temperature. Slide out cabinet to retrieve tested samples, wipe fixtures clean, exit software and cut main power supply.
