Conical Mandrel Bending Tester
Model No. :
Model No. : 1605
Brand : BEVS
The BEVS 1605 is a robust, dedicated mechanical tester designed to quantitatively assess the flexibility, adhesion, and elongation properties of dry paint and organic coatings applied to metal sheet substrates. Unlike cylindrical models, the conical geometry subjects the specimen to a continuously decreasing radius of curvature, providing a detailed, single-test failure profile across a wide range of strain.
- Measures coating crack resistance
- Wide strain range in one test
- Compact and highly durable structure
− Features
- Conical Mandrel Geometry: Utilizes a precision conical axis ranging from a large end of Ø38 mm down to a small end of Ø3.1 mm over a 203 mm length, providing a continuous gradient of curvature in a single operation.
- Wide Strain Profile: The varying diameter allows for the simultaneous assessment of coating flexibility across a full spectrum of stress, from minor bending to extreme deformation, yielding comprehensive data.
- Robust Mechanical Construction: Built from high-quality steel to ensure exceptional durability and stability, guaranteeing repeatable test results under consistent operating conditions.
- Optimized Sample Handling: Capable of accommodating large coated specimens with a maximum size of 200 mm x 100 mm, suitable for standard industrial test panels.
- Benchtop Form Factor: Designed with a compact size of 280 x 280 x 95 mm (L×W×H) and a gross weight of 8 kg, making it suitable for stable desktop use in quality control laboratories.

FAQs
How does the Conical Mandrel test differ from the Cylindrical Mandrel test?
The Cylindrical test evaluates flexibility at a single, uniform radius per test. The Conical test uses a continuous range of radii (3.1 mm to 38 mm) in a single test, allowing technicians to find the exact point on the mandrel where the first crack appears, corresponding to the critical flexibility limit.
What is the main advantage of testing across a continuous radius?
The continuous radius eliminates the need for multiple test runs using different mandrel diameters, streamlining the testing process and providing a more precise, quantifiable result of the coating’s failure point and elongation percentage in one operation.
What determines the “failure point” in a Conical Mandrel test?
The failure point is determined by measuring the distance from the small end (3.1 mm diameter) to the first visible crack in the coating film after the panel has been bent.
Which industries primarily use this type of flexibility tester?
This instrument is critical for industries where coated materials are subjected to forming or deformation, including Coil Coatings, Automotive, Aerospace, Appliance manufacturing, and General Industrial Paint applications.
What is the maximum sample thickness recommended for this tester?
While the official specification is not provided on the partner page, Conical Mandrel Testers are typically designed for thin, flexible sheet metal substrates up to approximately 0.8 mm (0.032 inches) in thickness.
