Product Description
Cylindrical Mandrel Bend Tester
Features
- Max. panel size: 50 mm width x 1 mm thick
- Robust stainless steel mandrels, easy to install in seconds
- Sturdy pre-drilled frame ready to secure on workbench
The test is carried out by bending the coated sample panel around mandrels of different diameters until damage occurs. Procedures can be based on pass/fail or diameter to failure methods.
Robust Design and Premium MaterialsEngineered with mild steel and finished with a smooth powder coating, the Cylindrical Mandrel Bend Tester is built for durability and consistent performance. Its high-quality, interchangeable steel mandrels offer versatility for testing coatings across various diameters, ensuring reliable results each time.
Versatility and PrecisionWith up to 14 mandrels included per set, the tester provides comprehensive coverage for specimen thicknesses up to 1mm and mandrel diameters from 1mm to 38mm. It accommodates specimen widths up to 200mm, making it suitable for a wide range of coating flexibility tests in paint, varnish, and related industries.
Accurate Results and ComplianceThe bending method strictly follows ASTM and ISO standards for coating flexibility and adhesion testing. The manual display and stable base facilitate precise control, while the robust export packaging ensures safe delivery and longevity, making it ideal for manufacturers, suppliers, and laboratories.
FAQs of Cylindrical Mandrel Bend Tester:
Q: How is the Cylindrical Mandrel Bend Tester used in coating flexibility and adhesion testing?
A: This tester evaluates the flexibility and adhesion of coatings by bending a coated sample over a series of cylindrical mandrels of various diameters. The specimen is manually wrapped around each mandrel, and the coatings behavior is observed for cracks or detachment, according to ASTM/ISO standards.
Q: What types of coatings can be tested with this device?
A: The tester is suitable for assessing paints, varnishes, and other industrial coatings commonly applied to metal and similar substrates, making it ideal for manufacturers and laboratories evaluating coating performance.
Q: When should I use different mandrel sizes in a test?
A: Different mandrel diameters (from 1mm to 38mm) are selected based on coating flexibility requirements and specimen thickness (up to 1mm). Starting with larger diameters and progressing to smaller ones identifies the minimum bend radius the coating can withstand without damage.
Q: Where is the Cylindrical Mandrel Bend Tester typically used?
A: This equipment is widely used in quality control laboratories, manufacturing plants, and by exporters or suppliers in the paint, varnish, and coating industries across India and internationally for certification and product development.
Q: What is the standard process for a typical bend test using this device?
A: A sample is secured and manually bent over different mandrels in succession, observing the surface for cracks or loss of adhesion. Results are recorded as per relevant ASTM or ISO test procedures, providing a reliable measure of coating durability.
Q: How does this tester benefit manufacturing and quality control?
A: By providing a simple, manual, and accurate method for determining coating flexibility and adhesion, the tester helps manufacturers ensure their products meet strict quality standards, reducing failures and improving reliability in real-world applications.
Q: Is any electrical power required to operate the Cylindrical Mandrel Bend Tester?
A: No, the device is completely manual and requires no electricity, making it portable and convenient for use in a variety of work environments.
