Sealing ring low-temperature retraction testing machine

The sealing ring low-temperature shrinkage testing machine is suitable for low-temperature shrinkage cold resistance and dry resistance testing and research and development of vulcanized rubber components, plastics, special composite materials, and related products, as well as testing specifications for quality management engineering. Measure the temperature value of rubber and other materials when the deformation reaches the specified value with the gradual increase of temperature after being frozen at low temperature for a period of time through mechanical devices and displacement sensors.
