Fully automatic sponge compression deformation testing machine-As a precision equipment used to test the compression performance of soft materials such as sponges and foam, it is widely used in many fields such as material research and development, product quality inspection, etc.

1、 Equipment usage

1. Quality control: In the production process, the test chamber can be used to detect the deformation of sponge products after repeated compression or long-term compression, ensuring that the product elasticity meets relevant standards and actual usage needs. For example, for sponges used in furniture such as mattresses and sofas, testing can ensure that they will not be excessively deformed during daily use, which will affect comfort and service life.

2. Performance evaluation: Verify the mechanical stability of sponge materials. By simulating the compression conditions in actual usage scenarios, the deformation trend of sponges after periodic compression is detected to avoid product functional failure caused by material deformation, such as preventing channel blockage of filter materials and negative pressure failure of negative pressure drainage products caused by sponge deformation.

3. R&D optimization: Assist material R&D personnel in improving material formulas. The data provided by the test chamber can help R&D personnel understand material properties, optimize formulations, and improve key performance indicators such as sponge resilience and durability.

2、 Working principle

The test chamber mainly works in conjunction with the loading system, temperature control system, and data acquisition and processing system. The loading system adopts a stable and adjustable pressure application method, such as the hydraulic loading system, which is composed of hydraulic pumps, hydraulic cylinders, hydraulic valves and other components, and can accurately simulate actual compression loads of different degrees. During testing, place the sponge sample cut to standard size between the fixture and the positioning block. The fixture plate is usually made of metal material, with a flat and smooth surface, ensuring that the specimen is uniformly stressed during the compression process. Positioning blocks are based on different compression ratios.

3、 Core functions

1. Compression deformation test: According to relevant standards, the sponge is compressed under specified pressure, temperature, and time conditions. After the test is completed, the residual deformation after unloading is measured. This data intuitively reflects the ability of the sponge to maintain its shape under specific working conditions and is one of the important indicators for evaluating the quality of sponge materials.

2. Elastic recovery rate test: Accurately evaluate the elastic properties of materials by measuring the proportion of sponge that recovers to its original thickness after being compressed. A high elastic recovery rate means that the sponge can better restore its original state and maintain good performance after multiple uses.

3. Cyclic compression fatigue test: Simulate multiple compression scenarios of sponge in actual use, and detect its deformation trend after periodic compression. Through long-term cyclic testing, it is possible to predict the reliability and durability of sponge materials during long-term use, providing data support for the design life of products.

4、 Application Fields

1. Furniture manufacturing industry: Mattresses, sofas, seats and other furniture products extensively use sponge materials. The test chamber can be used to test the compressive strength, resilience, and durability of sponges, ensuring that furniture products can maintain good comfort and support performance during long-term use, improving product quality and user satisfaction, and enhancing the competitiveness of enterprises in the market.

2. Packaging materials industry: For products that use sponge as a cushioning packaging material, such as electronic products, precision instruments, etc., testing the compression deformation performance of sponge under different pressures can optimize packaging design, ensure effective protection of products during transportation and storage, and reduce the risk of product damage caused by poor packaging material performance.

3. Material research and development institutions: In the process of developing new sponge materials, the detailed testing data provided by the test chamber can help researchers gain a deeper understanding of material properties, provide scientific basis for material formula optimization and process improvement, accelerate the research and development process of new materials, and promote the innovative development of material science.
