Cylindrical Mandrel Tester

Bending coated sheet metal over a defined radius

is an indicator of the elongation and adhesion of a paint film at bending stress.

Pushen offers two types of mandrel bending testers,cylindrical mandrel and conical mandrel.

This is used for simple and quick testing of the flexibility of a coating by bending a coated panel

over a rod of known diameter and then examining the coating for caracking,flaking,or other damage.

● 12 mandrels of stainless steel

● Panels up to 50mm width can be tested

● Rod dia sizes：2，3，4，5，6，8，10，12，16，20，25，36mm

Procedure

– Apply the paint film on sheet metal strips

– Coat and dry film carefully to ensure reproducible results
