Conical-Type Bending Tester

The conical bending tester applies pressure to the specimen through a conical indenter, causing the material to bend and deform until it cracks, while recording the indentation depth at the moment of cracking. It is used to detect the flexibility and crack resistance of materials such as coatings and plastics. In the coatings, inks, and plastics industries, it is employed for quality control purposes.
Selection
When selecting, consider the type and thickness of the test material, and match the indenter size and load range. Verify the instrument's accuracy and calibration certificate, and check its ease of operation. Refer to relevant testing standard requirements, and evaluate the equipment's durability and maintenance costs.
