Conical Mandrel Bend Tester for Paint Flexibility

Bench-mounted conical mandrel with a lever for bending coated metal panels over a tapering diameter to find the point of film cracking. Used by paint labs for flexibility and elongation checks of coil and general industrial coatings.

Specification

A coated panel is clamped against the cone and bent through about 135 degrees in 15 seconds. The distance from the small end of the cone to the crack in the film is measured. The test is a quick and objective flexibility measure.

Features

• Cone from 3.1 mm to 38 mm diameter
• Hardened chrome plated mandrel and lever
• Clamp and bending roller for uniform pressure
• Panel size up to 100 x 150 mm
• Provided with scale and magnifier
