Conical Mandrel Bend Tester

NEURTEK mandrels, both conical and cylindrical, are designed to perform bending tests on coatings applied to metal substrates. These tests help assess the flexibility, adhesion, and mechanical resistance of coatings when subjected to deformation.

Manufactured by NEURTEK, these devices stand out for their precision, durability, and full compliance with leading international standards.

What is a bending mandrel used for?

Bending tests are commonly used in coating quality control. The test involves flexing a coated panel to determine the point at which the coating begins to crack or delaminate. It helps evaluate:

• Coating elasticity.
• Adhesion to the substrate.
• Performance under mechanical stress.

Conical Mandrel

Designed according to UNE EN ISO 6860 and ASTM D 522-93ª standards, the conical mandrel features a 200 mm long metal cone with a gradually decreasing diameter from 37 mm to 3 mm.

The test is performed by bending the coated sample over the cone to determine the minimum diameter at which cracks begin to appear.

Key features of the conical mandrel:

• Diameter range: 37 to 3 mm.
• Total length: 200 mm.
• Continuous visual assessment in a single operation.
• Rugged, deformation-resistant design.
• No calibration required (certification not available).

Advantages of NEURTEK Mandrels

• Robust construction for long-term use.
• Easy operation thanks to ergonomic lever design.
• Clear results in one step.
• Compatible with major international standards.
• Ideal for quality control and R&D labs.

What tests can you perform?

NEURTEK bending mandrels are ideal for evaluating:

• Industrial coatings.
• Paints and lacquers on metal surfaces.
• Products subject to bending or mechanical stress.
• Development of new materials in laboratory environments.

Both conical and cylindrical mandrels are essential tools for assessing coating adhesion and mechanical strength. They play a key role in ensuring durable, high-performance products in real-world applications.
