KJ-3091 Electronic Box Compression Testing Machine 20×12×10cm with 40% 30% 25% 20% Compression Ratios
The KJ-3091 Electronic Box Compression Testing Machine is designed for conducting static compression tests on rubber materials. This 20×12×10cm testing instrument features multiple compression ratios and precise panel thickness options for accurate material analysis.
This machine performs rubber static compression testing by compressing standard samples to specified ratios, followed by oven heating and post-test measurements to determine compression deformation characteristics.
- Place standard sample between panels and tighten screws
- Compress to specified ratio (40%, 30%, 25%, or 20%)
- Transfer to oven for regulated heating period
- Remove sample after specified time and cool for 30 minutes
- Measure thickness and calculate compression deformation
