Project Description

corrugated fibreboard compressive strength tester

Crush Tester for Paper, Board and Corrugated Fibreboard

Compression Testing Machine is the most commonly used crush tester used to determine the compressive strength of paper, board and fibreboard.

It is a piece of multi-purpose paper and packaging testing equipment. Different test items can be conducted as long as this machine is configured with corresponding auxiliary equipment. This instrument has many other different names, such as Ring Crush Tester, Flat Crush Tester, Edge Crush Tester or Edgewise Crush Tester, Pin Adhesion Tester, Corrugating Medium Tester, Corrugated Crush Tester.

Test Items

RCT: Ring Crush Test Sampling Device and Test Piece Holder need to be equipped.

ECT: Edge Crush Test Sampling Cutter & Guide Blocks need to be equipped.

FCT: Flat Crush Test Sampling Device needs to be equipped.

PAT: Pin Adhesion Test Fixture needs to be equipped.

CMT: Corrugating Medium Fluter & Rack and Comb needs to be equipped.

CCT: Corrugating Medium Fluter & Edge Crush Specimen Holder need to be equipped.

Feel free to contact AMADE for consulting more details on sampling devices and auxiliary equipment.


The core components of this equipment acting on the test piece are two platens: An upper and a lower platen. Each is large enough to accommodate the test piece completely and sufficiently rigid to withstand significant deformation by the compressive forces. The platens are mounted to have not more than 0.05 relative movement in the horizontal plane, and their surfaces are parallel and flat to each other.

The lower platen is movable towards the other at a constant speed. A precision load cell in the upper platen starts detecting and collecting the compressive force once the lower platen contacts the upper platen via the sample assembly. The real-time values are transmitted to the machine’s control center for analysis and presentation, along with the increasing force exerted on the specimen by the moving platen. The maximum force per unit length that a test piece can support until the onset of failure when a compressive force is applied can be measured.
