Vertical type freezing tester

HY-769L vertical low-temperature bending test machine
Purpose: This machine adopts a vertical design, so there is no need to bend over when clamping samples, making it easy to operate and occupying a small space. Used to test the bending (twisting) or stretchability of materials such as leather, synthetic leather, rubber, finished shoes (shoe sizes: 20 to 54), upper leather, sole, etc. in low-temperature environments.

Compliant with standards: GB/T8948, QB/T 1471, QB/T2224, GB/T20991-2007, SN1309.2, GB/T15107, etc
