The ring crush tester can cooperate with a variety of materials to do a full range of tests, and conduct a variety of paper quality tests on paper packaging materials. The RCT ring crush tester is mainly used to test corrugated core paper, box board (kraft liner paper), and corrugated board. The machine combines multiple functions in one. There are 5 types of test tests that can be performed: ring crush test (RCT), flat crush test (FCT), edge crush test or edgewise crush test (ECT), pin adhesion test (PAT) and corrugating medium test (CMT)
The optional jigs for Wewon’s crush tester: Optional configuration: parallel sampler; ring pressure sampler, ring pressure clamp, flat pressing fixture, gluing strength clamp. This machine is equipped with various fixture accessories to test the ring compressive strength of the base paper, the flat/side compressive strength of the cardboard, and the bonding strength, so that the paper manufacturer can control the production cost and improve the product quality. Ring crush tester from Wewon Tech will comply with the test standard such as TAPPI T472, TAPPI T808, TAPPI T810, TAPPI T811, TAPPI T818, JIS P8126, GB/T 2679.6, GB/T 2679.8, GB/T 2679.17, GB/T 6546, GB/T 6544, GB/T 6548

Caution should be used when testing linerboard less or greater than the specified thickness as the results may be less reliable. For papers thinner than 0.28 mm (0.011 in.), test values may result from a combination of both buckling failure and pure compression. For papers thicker than specified, strain within the sample arising from bending the specimens into a cylinder may impact test results｜Ring Crush Tester
