What is a bending testing machine?
In the fields of industrial production, materials research and quality control, bending testing machines are important testing equipment used to evaluate the durability and performance of materials under repeated bending or bending conditions. This article will introduce in detail the definition, working principle, application scenarios of the bending testing machine, as well as the technical progress related to it in recent hot topics.
1. Definition of bending testing machine
A bending testing machine is a device that tests the fatigue resistance, flexibility and durability of materials or products by simulating the bending forces they experience in actual use. It is widely used in metal, plastic, rubber, textiles, electronic components (such as flexible screens) and other fields.
2. Working principle
The bending testing machine completes the test through the following steps:
| steps | Description |
|---|---|
| 1. Sample fixation | Fix the material to be tested on the fixture to ensure its position is stable. |
| 2. Set parameters | Input parameters such as bending angle, frequency, number of cycles, etc. |
| 3. Start testing | The machine repeatedly bends the sample according to the settings. |
| 4. Result analysis | Record the number of material breaks or property changes and generate a report. |
3. Application scenarios
The applications of bending testing machines cover many industries. The following are typical scenarios:
| Industry | Application examples |
|---|---|
| Electronic manufacturing | Test the bending resistance of flexible screens and circuit boards. |
| Automobile industry | Evaluate the fatigue life of rubber seals and metal parts. |
| Textile industry | Detect the strength changes of fiber fabrics after repeated folding. |
| packaging materials | Verify the bending resistance of cartons and plastic films. |
4. Recent hot topics and technological progress
In the past 10 days, discussions related to bending testing machines have mainly focused on the following areas:
1.Flexible electronic device testing: With the popularity of foldable screen mobile phones (such as the Samsung Galaxy Z Fold series), manufacturers have increased their requirements for screen bending life to more than 200,000 times, promoting the accuracy upgrade of testing machines.
2.New energy battery materials: The bending performance of lithium battery separators directly affects safety, and testing machines help develop more durable materials.
3.Automation and AI integration: New testing machines are beginning to be equipped with sensors and AI algorithms to predict material failure points in real time and reduce manual intervention.
The following are statistics on some hot topics (data source: public discussion popularity on the entire network):
| topic | Search volume (daily average) | Main discussion platform |
|---|---|---|
| Folding screen bending test | 12,000 times | Weibo, technology forum |
| Lithium battery material testing | 8,500 times | Zhihu, industry websites |
| Intelligent bending testing machine | 5,300 times | Station B, YouTube |
5. Key indicators for selecting a bending testing machine
Please pay attention to the following parameters when purchasing:
| indicator | Description |
|---|---|
| Maximum bending angle | Typically 180° coverage is required to meet most testing needs. |
| Test frequency | High frequency (such as 60 times/minute) can shorten the test time. |
| load capacity | Select according to material strength (such as 0.1N~500N). |
| Data logging function | It would be better to support exporting curve charts and Excel reports. |
Summary
The bending testing machine is one of the core tools for materials science and industrial quality inspection, and its technological development closely follows market demand. From flexible electronics to new energy fields, high-precision and intelligent equipment are becoming industry trends. Enterprises need to consider their own testing needs when purchasing, focusing on the reliability, automation and data support capabilities of the machine.
