The shock testing system of SKT series are mainly applicable to shock resistance tests in such fields as electronic products, aerospace, shipping, military industry, automotive parts and transportation. Shock tests in form of half sine wave, final peak saw tooth wave or trapezoidal wave shock tests can be carried out by selecting different waveform generators.
Features :
a. Free drop type shock tester using hydraulic lifting and HP fluid braking.
b. Use of pneumatic-hydraulic boosting and strong friction brake to prevent secondary shock braking.
c. Shock measurement device: single-channel data acquisition, simultaneous acceleration data
measurement, storage, report printing, data callback, database management of two channels.
d. Use of rubber module, producing a wide range of half sine pulse with arbitrary action time.
e. Availability for equivalent drop test of packing boxes.
Applications
1. Fragility test of products.
2. Shock standard test of products.
3. Fragility test for digital cameras, smart phones, tablets, mobiles, displays, small household appliances, cosmetics, electronic parts, large-sized office machine, refrigerator and etc.
4. Shock standard test for digital cameras, smart phones, tablets, mobiles, displays, small household
appliances, cosmetics, electronic parts large-sized office machine, refrigerator and etc.
5. Free drop equivalent test packaged freights.
