Conical Mandrel Bend Tester

conical mandrel tester is used in the determination of elasticity, adhesion and elongation of paint on sheet metal. The specimen can be bent on part of or along the entire length of the mandrel, and the results (cracks) corresponding to different test diameters can be observed in a single operation.

Elasticity and resitance to deformation are part of the key physical properties required in the coatings industry. Essentially there are three different test methods which are used to determine a coating's performance under different deformation conditions.

Bend Test A coated metal sheet is bent over a cylindrical or conical mandrel and the coating observed for cracks and discolouration.

The conical mandrel tester is used in the determination of elasticity, adhesion and elongation of paint on sheet metal. The specimen can be bent on part of or along the entire length of the mandrel, and the results (cracks) corresponding to different test diameters can be observed in a single operation.

Conical Mandrel: The bending of the plate is executed over a cone of 200 mm in length and decreasing diameter from 37 mm to 3 mm. The maximum lecture is used on the diameter on which cracks begin to appear.
