GFT-01 Flex Durability Tester

GFT-01 gelbo flex tester is also known as Tester for fleksibel holdbarhet, assesses how well materials such as films, composites, and coating films endure repetitive strain. It helps to create flex failure on samples so user can identify pinholes and permeation ability change in the sample structure. The importance of achieving strong flex crack resistance lies in reducing the risk of packaging developing holes during distribution. This is crucial for keeping the package intact throughout its journey, ensuring the contents inside remain protected. The tester plays a key role in evaluating the ability of materials to withstand repeated flexing, contributing to the overall durability and reliability of packaging in various industries. Our Gelbo flex tester is designed for accurate Gelbo flex testing, following the standard Gelbo flex test method. This essential equipment, including the Gelbo flex resistance tester, is used to evaluate the durability and flexibility of materials.

2.Why do you need GFT-01 Gelbo Flex Tester?

A critical property of flexible barrier materials is their ability to withstand repetitive strain, known as flex durability or Gelboflex resistance. Strong flex crack resistance is essential as it lowers the risk of package failure during distribution, safeguarding package integrity.

3.Advantages

GFT-01 Gelbo Flex Tester is equipped with PLC control and a user-friendly HMI touch screen interface. It encompasses five standard test modes and incorporates four test stations, allowing users to easily transition between long and short stroke modes by the selectable test conditions A, B, C, D, and E. Additionally, the inclusion of a micro printer ensures convenient and efficient data output. GFT-01 Gelbo Flex Tester offers a sophisticated and intuitive solution for material testing needs.

4.Test Principle  

In GFT-01 Gelbo Flex Tester, a sample measuring 200 by 280 mm is affixed to the mandrels. The flexing process involves a combination of twisting and horizontal compression, repeatedly subjecting the film to both actions. Specifically, the setup initiates a twisting motion spanning 440 degrees within the first 90 mm of the stroke, followed by a linear horizontal motion of 65 mm. The entire cycle occurs at a speed of 45 cycles per minute.

Users have the option to select from five preprogrammed test conditions.

Mode A– Full flex for 1 hour (2,700 cycles),

Mode B– Full flex for 20 minutes (900 cycles),

Mode C– Full flex for 6 minutes (270 cycles),

Mode D– Full flex for 20 cycles,

Mode E– Partial flex for 20 cycles.
