The Ring And Edge Crush Tester is an essential instrument for evaluating the strength of corrugated boards and paper materials. When paired with the appropriate fixtures, this single machine can perform six major tests:
- Ring Crush Test (RCT)
- Edge Crush Test (ECT)
- Flat Crush Test (FCT)
- Concora Medium Test (CMT)
- Corrugated Crush Test (CCT)
- Pin Adhesive Test (PAT)
The tester integrates a high-precision load cell, digital controller, and rigid compression frame to ensure stable, repeatable results—ideal for packaging manufacturers, carton converters, and QC laboratories.
