Corrugated Fibreboard Pin Adhesion Test Attachment China Manufacturer

Pin Adhesion Test Fixture is an indispensable sample holder when measuring the force required to separate corrugated board between the flute tips of corrugated medium and its linerboard facings.

Determination of adhesion of the corrugated medium to its facings plays an essential role in judging the quality of corrugated boards and corrugated cartons. The ply adhesion test provides a means of evaluating the bond’s strength and is used to check some manufacturing defects, such as poor adhesive penetration, spotty adhesion, and containerboard with low internal bond strength.

The pin adhesion test is carried out using a compression testing machine.

AMADE TECH Pin Adhesion Test Fixture is made up of the pressure part and the support part to separate the respective adhered parts of the test piece with an evenly distributed load. Both parts consist of pins and metal base plates. The pins and base plate are separate from each other to facilitate you to mount the specimen and accommodate corrugated boards of more extensive flute distances. The effective lengths of the pressure pin and the support pin are 57.2 mm and 69.8 mm respectively. Seven support pins of specified diameters, including Flute A, B, C, and E, are allowed to rest on the same support seat. Six pressure pins of different diameters come with corresponding pressure base plates based on different pin distances. The pressure pins and support pins are inserted into the flutes of the specimen according to the specified arrangement. The force is exerted downward on the pressure pins during the test until separating the facing from the flute tips occurs.
