Test Method of Flex Resistance Tester

1. Working Principle

The technical principle of the Flex Resistance Tester is based on a closed-loop control system integrating mechanical transmission and sensor feedback. The instrument typically uses a PLC (Programmable Logic Controller) as the core control unit. Test parameters, such as flexing speed and cycle count, can be set through buttons or a touchscreen interface. The system then drives stainless steel clamps to apply reciprocating motion to the test specimen.

During the flexing process, the digital display system continuously records changes in force values and deformation data, generating visual test reports for analysis.

For example, textile materials used in garments are frequently subjected to repeated bending and folding movements at areas such as elbows and knees during daily wear. The tester can simulate these repeated mechanical actions to evaluate performance indicators such as fiber breaking strength, coating peeling rate, and material durability, helping manufacturers optimize production processes and improve product quality.

2. Testing Procedure

The testing process of the Flex Resistance Tester mainly consists of the following steps:

Step 1: Test Specimen Preparation

According to the relevant testing requirements, specimens with appropriate dimensions are cut from the packaging material to be tested. Necessary pretreatment procedures, such as cleaning and drying, are carried out to ensure consistent test conditions.

Step 2: Specimen Installation

The prepared specimen is securely mounted onto the Flex Resistance Tester. Proper fixation ensures that the specimen remains stable during the test without displacement, slipping, or unintended deformation.

Step 3: Setting Test Parameters

According to the specified test requirements, the operator sets the required testing parameters, including:

Flexing force

Flexing frequency

Test duration

Number of cycles

The instrument then performs the test according to the preset conditions.

Step 4: Start Testing

After all parameters are confirmed, the tester is started to perform the flexing test. During the testing process, the instrument continuously monitors and records changes in the specimen’s performance, providing real-time data on material behavior under repeated mechanical stress.

Step 5: Result Analysis

After completion of the test, the collected data is analyzed to evaluate the flex resistance performance of the packaging material.

The final results are used to determine whether the material meets relevant quality standards and performance requirements, providing reliable data support for material selection, quality control, and product improvement.
