Paint Film Cone Bending Tester, Conical Mandrel Tester Tapered Shaft Paint Film Flexibility Bending Instrument

This unit is a special instrument to evaluate the cracking resistance or peeling off from metal plate when the coating of color paint and related products is bent around the cylinder shaft under standard conditions.Working principle:Insert the test plate between the tie rod and the conical shaft, and clamp the lever with a splint, turn the shaft from front to back (to bend the test plate around the conical shaft), and measure it according to the crack position of the coating on the test plate its peeling properties.Standards compliant:Comply with:ISO6860-1984(E),ASTME522-60(1979),BS3900；PartE11:1985GB/T11185-89 execution standards.Parameters:Material: stainless steel + ironTest plate substrate thickness: ≤ 0.03inch (0.8mm)Shaft rod size Shaft small end diameter: 0.1inch (3.2mm)Shaft rod size Shaft big end diameter: 1.5inch (38mm)Taper shaft length: 8inch (203mm)Size:11*5.5*12.4 inch (280*140*315mm)Package Including:1*Paint Film Cone Bending Tester

• 【Parameter】 Material: stainless steel + iron, Test plate substrate thickness: ≤ 0.03inch (0.8mm), Shaft rod size Shaft small end diameter: 0.1inch (3.2mm), Shaft rod size Shaft big end diameter: 1.5inch (38mm), Taper shaft length: 8inch (203mm), Size:11*5.5*12.4 inch (280*140*315mm).
• 【Application】This unit is a special instrument to evaluate the cracking resistance or peeling off from metal plate when the coating of color paint and related products is bent around the cylinder shaft under standard conditions.
• 【Working Principle】 Insert the test plate between the tie rod and the conical shaft, and clamp the lever with a splint, turn the shaft from front to back (to bend the test plate around the conical shaft), and measure it according to the crack position of the coating on the test plate its peeling properties.
• 【Operating Steps】Carefully cover test panel with paper between mandrel and draw bar and clamp the probe.Fold the test panel around the cone by using the manually operated arm.Bend uniformly at 180°within 15 seconds, examine the coating for cracks.
• 【GB/T11185-89 Execution Standard】The varying mandrel diameter 0.1inch- 1.5inch(3.2mm- 38mm) stretches a coating through a gradient of distension, allowing precise determination of adhesion characteristics.
