1. Productmajor function

The air-cooled series electric vibration testing system has many advantages such as wide frequency, excellent indicators, high reliability, small footprint, easy mobility, and simple operation. Currently, there are multiple types of vibration tables available for selection in this series. The range of excitation force is from 1kN to 70kN, and the maximum load is from 70kg to 1000kg. Widely used in aviation, aerospace, weapons, ships, communications, automotive, electronics, electrical engineering, home appliances and other fields. We can provide comprehensive testing equipment for multiple environments such as climate and mechanics.
The vibration testing system is mainly used for conducting vibration and impact environment tests, environmental stress screening tests, reliability tests, and fatigue tests on products to assess their lifespan.
