Product Description
Conical Mandrel Bend Tester
Features
- Sturdy construction
- Long service life mandrel
A practical unit to test the elasticity and elongation of various coatings. The sample panel is clamped and bent by rotation of the roller frame onto the 200 mm length x Ø3 ~ 37 mm conical mandrel.
This allows easy identification in a single operation the coating failure at specified diameter, over part or entire mandrel length.
Robust Mandrel ConstructionConstructed from hardened tool steel and finished with a polished surface, the mandrel provides excellent resistance to wear and maintains measurement accuracy. Its tapered shape allows for thorough flexibility testing across a wide diameter range, ensuring precise evaluation of coating performance according to ASTM D522 and ISO 1519 standards.
Manual Inspection for Reliable AssessmentThe tester utilizes manual visual inspection, allowing operators to directly observe the effects of bending on coatings. This approach offers high reliability in determining flexibility and adhesion, and the setup is optimized for laboratory, indoor environments. No power source is required, facilitating easy operation and maintenance.
Versatile Panel CompatibilityWith a capacity for panels up to 150 mm x 100 mm and a broad measurement range, the Conical Mandrel Bend Tester supports a variety of sample types. Stainless steel and hardened steel core components guarantee stability, while the export-quality wooden box ensures the devices protection during transport or trade.
FAQs of Conical Mandrel Bend Tester:
Q: How does the Conical Mandrel Bend Tester evaluate coating flexibility and adhesion?
A: This tester works by manually bending coated metal panels over a tapered mandrel of hardened tool steel. Observers visually inspect the coating for cracks, delamination, or other failures, assessing flexibility and adhesion as per ASTM D522 and ISO 1519 standards.
Q: What benefits does using a hardened tool steel mandrel provide?
A: The hardened tool steel mandrel offers high durability and a polished finish, maintaining precise diameter tolerances (0.1 mm) and resisting wear, which ensures reliable and repeatable test results over extended use.
Q: Where is the Conical Mandrel Bend Tester typically used?
A: This equipment is designed for laboratory, indoor environments and is widely employed by manufacturers, exporters, importers, suppliers, and traders within India for coating evaluation and research.
Q: What types of test samples can be used with this tester?
A: The device accommodates metal panels and coated substrates up to 150 mm x 100 mm in size, making it suitable for testing a broad range of industrial coatings and substrate combinations.
Q: When should manual visual inspection be performed during the testing process?
A: Manual visual inspection is performed immediately after bending the coated panel over the mandrel, examining the test area for signs of coating cracks, peeling, or loss of adhesion, which indicates flexibility and durability.
Q: What is the process for using the Conical Mandrel Bend Tester?
A: Users manually clamp the test panel, select the desired mandrel diameter within the range, and bend the panel over the mandrel. The coating is visually inspected to determine if it meets flexibility and adhesion requirements per industry standards.
Q: How is the tester packaged for export and transport?
A: The Conical Mandrel Bend Tester is securely packed in an export quality wooden box that protects the equipment during shipping, handling, and storage, ensuring the instrument arrives undamaged and ready for use.
