Overview
The TQC Conical Mandrel Tester SP1831, a simplified version of the TQC Conical Bend Test Pro (SP1830), is a laboratory device used to bend coating test plates on conical mandrels to assess the resilience or resistance of coatings. The device tests metal test plates for cracking, elongation, or separation when bent, in accordance with ISO 6860 and ASTM D522 standards.
Features
1. Simplified design and easy operation
2. Sturdy construction, composed of anodic oxidation of aluminum and stainless steel
3. The bending arm is equipped with a large knob for easy bending operation
4. conical mandrel design allows evaluation of coating resilience in a single test from 3.1 to 38mm diameter
5. Fix the test board with two clamping knobs, turn clockwise or counterclockwise to tighten or release
Principle
The tester uses a bending arm to apply force by fixing the coating test plate to a conical mandrel. The shape of the conical mandrel allows the test plate to deform at different diameter positions, thus checking the resilience of the coating in a single test in the 3.1mm to 38mm diameter range and evaluating the cracking, elongation or separation of the coating.
Applications
Automotive, Coatings Industry, Laboratory, Coatings
Standards
ASTM D522、ISO 6860
Steps
1. Place the test board on the conical mandrel
2. Use two clamping knobs to fix the test plate and turn it clockwise to tighten it
3. Operate the large knob on the bending arm to apply the bending force
4. Observe the performance of the coating during bending
5. After the test is completed, turn the clamping knob counterclockwise to release the test plate
Notice
• The thickness of the test plate should not exceed 0.8mm.
• When operating the clamping knob, pay attention to the direction of rotation. Tighten clockwise and release counterclockwise.
Equipment should be placed on a stable workbench for use
• Regularly check whether all parts of the equipment are in good condition
• Make sure the surface of the test board is clean and free of contamination before testing
