Mandrel Bend Testing

Mandrel Bend Testers are specialized devices used to evaluate the flexibility, ductility, and adhesion of paint or coating films. They help determine whether a material can endure bending stresses without cracking or detaching from its substrate. These tests are crucial in industries where coatings must maintain performance under mechanical stress, such as automotive, construction, and manufacturing.

Conical Mandrel Tester: Used to measure resistance to cracking by bending the coating over a conical shape, providing results based on the gradation of stress.

Cylindrical Mandrel Tester: Evaluate coating flexibility and resistance with precision cylindrical mandrel testers, designed for reliable testing of paint and varnish applications.

Hinge-Type Mandrel Bend Tester: Equipped with multiple hinges of different diameters, these allow for quick and efficient testing, offering both “pass/fail” assessments and progressive testing with decreasing diameters.

T-Bend Tester: A T-Bend Tester evaluates the flexibility and adhesion of coatings on metal substrates by bending panels into a “T” shape, identifying cracks or failures.

These instruments adhere to International Standards such as ISO, ASTM, and DIN, ensuring accuracy and compliance with global testing benchmarks. Common applications include quality control in paint manufacturing and product durability assessments.
