High and Low Temperature Relaxation Creep Tester: Advanced Analysis for Material Performance Under Extreme Conditions
The High and Low Temperature Relaxation Creep Tester is a cutting-edge instrument engineered to evaluate the relaxation and creep properties of diverse materials—including plastics, rubbers, leathers, and fabrics—under a wide range of temperature extremes. Its core testing principle involves subjecting specimens to controlled stretching or compression to a specified displacement or force, then maintaining these conditions over prolonged periods while monitoring changes in force or displacement. By simulating both high and low temperature environments, the tester reveals how materials respond to sustained stress in real-world scenarios, from freezing cold to intense heat, providing critical data for product development, quality control, and material selection across industries.
The tester adheres to rigorous international and regional standards, ensuring its results are credible, consistent, and globally recognized:
- GB/T 1685 (Method A): A Chinese national standard specifying methods for testing rubber’s compression stress relaxation, with relevance to other elastic materials like plastics and fabrics.
- GB/T 11546.1: Another key Chinese standard focusing on plastic and rubber performance under temperature-induced stress, emphasizing relaxation characteristics in extreme thermal conditions.
Compliance with these standards guarantees that test data aligns with industry benchmarks, making the tester an essential tool for manufacturers, laboratories, and regulatory bodies seeking to validate material reliability.
Precision Sensing Technology
Equipped with a high-resolution force sensor, the tester captures real-time changes in force with exceptional accuracy. This sensor records even the smallest fluctuations in stress as materials relax or creep over time, ensuring that subtle performance shifts—critical for applications like automotive gaskets or aerospace seals—are not overlooked. The sensor’s sensitivity, combined with advanced data logging, provides a detailed timeline of material behavior, enabling in-depth analysis of relaxation rates and creep tendencies.
Accurate Deformation Control
A servo motor-driven electric cylinder powers the tester’s deformation system, maintaining constant compression or stretch deformation throughout the test duration. This technology eliminates drift or variability in displacement, ensuring that specimens remain under precisely controlled conditions—whether stretched to a fixed length or compressed to a specific thickness. Such stability is vital for long-term tests, where even minor deviations can skew results, particularly when evaluating materials like rubber, which may exhibit gradual relaxation under sustained strain.
Multi-Station Efficiency
Featuring 3 independent test stations (with expandable configurations available), the tester enables parallel testing of multiple specimens. Each station operates with separate temperature and stress controls, allowing simultaneous evaluation of different materials or the same material under varying conditions (e.g., comparing a rubber specimen at -40℃ to another at 150℃). This multi-station design significantly reduces testing time, making it ideal for high-throughput quality control checks or comparative studies between material formulations.
Reliability and Safety Features
- Power Failure Protection: In the event of a power outage, the tester automatically saves test parameters and resumes operation once power is restored, preventing data loss and minimizing downtime—especially critical for long-duration tests that may span days or weeks.
- Comprehensive Electrical Safeguards: Built-in protections against over-current, over-voltage, under-current, and under-voltage conditions shield both the equipment and specimens from damage, ensuring uninterrupted operation and extending the tester’s lifespan.
- Temperature Stability: The tester’s thermal control system maintains precise temperatures within the -60℃～200℃ range (with customizable options for broader extremes), preventing thermal fluctuations that could affect material behavior. This stability is achieved through advanced insulation, uniform air circulation, and a high-precision temperature sensor with 0.1℃ resolution.
The High and Low Temperature Relaxation Creep Tester is indispensable for evaluating materials across a diverse range of industries:
- Automotive: Testing rubber seals, plastic components, and fabric gaskets to ensure they withstand temperature extremes in engines, cabins, and undercarriages.
- Aerospace: Evaluating materials for aircraft interiors and exteriors, which must resist creep and relaxation at high altitudes (cold) and during engine operation (heat).
- Textiles and Apparel: Assessing fabrics and leathers used in outdoor gear, ensuring they maintain shape and strength in freezing or hot environments.
- Consumer Goods: Validating plastics in appliances (e.g., refrigerators, ovens) to prevent deformation under sustained use at extreme temperatures.
- Construction: Analyzing plastic and rubber materials in building seals and insulation, ensuring they perform reliably in climates ranging from arctic to desert.
- Versatile Temperature Range: From -60℃ to 200℃ (with customization options), the tester simulates nearly any environmental condition, making it suitable for global applications.
- Unmatched Precision: With 0.001mm displacement resolution and full-range automatic force measurement, it captures even the most subtle material changes, critical for high-performance applications.
- User-Centric Design: The compact footprint (1030×800×1650mm) fits into most laboratory spaces, while intuitive controls (via a PLC and HMI interface) simplify operation, reducing training time for technicians.
In summary, the High and Low Temperature Relaxation Creep Tester combines advanced thermal control, precision sensing, and multi-station efficiency to deliver actionable insights into material behavior under extreme conditions. Whether used in research and development or quality assurance, it empowers industries to engineer products that stand the test of time—even in the harshest environments.
