Upper Leather Flexing Tester ISO 4643
Meet the standard
GB/T20991-2007. EN ISO. SATRA TM25. ISO 4643 and other standards.
Main uses
VAMP VAMP leather extension testing machine with a certain frequency of zigzag test, observe the change of the surface of the test piece, whether the surface of the wrinkle and crack and its severity to evaluate the zigzag resistance of the test material.
Product Advantages
Measures Key Durability: Evaluates the flexing endurance and resistance to cracking of shoe upper materials, a crucial factor for footwear lifespan and appearance.
Standard Compliant: Designed to meet relevant national and international standards (SATRA TM25. ISO 4643. GB/T 20991. EN ISO 20344 sections on upper flexing) for testing upper material flexing resistance.
Simulates Wear on Upper Materials: Replicates the bending and stretching stresses experienced by the shoe vamp during walking.
Evaluates Resistance to Wrinkles/Cracks: Provides a method to assess the material's propensity to develop surface damage from flexing.
Provides Objective Visual Assessment Criteria: Evaluation is based on observing and assessing the severity of wrinkles and cracks according to standard criteria after testing.
Multiple Testing Stations: Available with options for testing multiple samples simultaneously (4 or 12), increasing testing throughput.
Controllable Test Parameters: Allows for precise control of flexing speed, stroke, and clamping angle.
Quantitative Result: Results are based on the number of flexing cycles performed until a specified damage level or after a fixed number of cycles.
