High and Low Temperature Spring Tension and Compression Fatigue Testing Machine
Category：Torsion Testing Machine
Introduction
The High and Low Temperature Spring Tension and Compression Fatigue Testing Machine is designed for fatigue life testing of various elastic components, including springs, tension and compression springs, shock absorbers, locomotive springs, valve springs, gas springs, air springs, wave springs, disc springs, and other metal components.The machine can perform fatigue tests under specified environmental conditions and evaluate the performance, durability, and service behavior of products after environmental exposure. It is equipped with dedicated testing software integrating test control, data acquisition, and data processing functions.The equipment can simulate the actual vertical working conditions of specimens and perform millions of fatigue cycles as well as tension and compression tests. It is widely used in automotive, railway, machinery, spring manufacturing, aerospace, and research laboratories for product development, reliability verification, and quality inspection.
Applications
Used for fatigue life testing of various springs and elastic components, including compression springs, tension springs, shock absorber springs, locomotive springs, valve springs, gas springs, air springs, wave springs, and disc springs under high or low temperature conditions. It is widely applied in automotive, railway, machinery, spring manufacturing, and research laboratories.

Main Features
Adjusts spring amplitude and test frequency according to spring technical requirements.
Equipped with LCD Chinese character display; test cycles and frequency can be preset through the program for automatic operation.
Automatically stops when the preset number of test cycles is reached.
The motor and reducer drive a cam mechanism, which moves the connecting rod reciprocally to achieve repeated compression and extension of the spring.
Simple operation, stable running, and reliable performance.
Supports automatic control, data acquisition, and analysis through dedicated testing software.
Capable of long-term fatigue testing with more than one million cycles.
Suitable for fatigue life evaluation under high and low temperature environmental conditions.
