  • Salt spray test

    Test the rust proof capacity

    The purpose of salt spray testing is to determine the corrosion resistance and longevity of materials, which plays an important role in product development, quality control and material selection. The test is performed in a laboratory environment where the specimen is exposed to a salt water mist to simulate conditions in a marine environment or other corrosive environment.

    In a salt spray test, the specimen is usually a metal or other material with an anti-corrosion coating. The specimen is placed in a salt spray test chamber in which a salt water mist is generated by a spray device. The specimen is exposed to high humidity and salt water mist for 48 hours.

    By observing the corrosion of the specimen, the corrosion resistance of the material or coating can be assessed. The test results are rated according to the degree of corrosion on the surface of the specimen, and all of our products pass the 48-hour medium-sized salt spray test at level 9.

    However, it is important to note that the salt spray test only simulates a specific corrosive environment and other factors such as the effects of climate, humidity, temperature and other chemicals need to be taken into account for practical applications.

  • Hardness test

    Test the hardness of product

    Hardness testing is a common method in materials science used to measure the hardness or resistance to deformation of a material. For hinge metal hardness testing, here are a few things to keep in mind:

    There are different hardness test methods and test equipment for different hinge metal materials and testing needs. For example, the commonly used hardness test methods include Brinell hardness, Rockwell hardness and Vickers hardness, while the test equipment includes Brinell hardness tester, Rockwell hardness tester and Vickers hardness tester.
    According to the specimen material and the standard requirements of the relevant products, to determine the appropriate range of hardness index: different materials of hinge metal has different hardness range, need to determine the appropriate range of hardness index according to the specific standards and requirements.

    The hardness test results should be recorded and compared with the standard requirements in time, and the production parameters should be adjusted in time: by comparing the hardness test results with the standard requirements, it can be judged whether the hardness of the hinge metal meets the requirements. At the same time, adjusting the production parameters according to the test results can optimise the production process and improve product quality.

  • Life cycling test

    Test the life cycling of product

    Different hinge products have different life test standards. We adopt ISO 9001:2008 which is the standard of quality management system, applicable to all types of products, including products using hinges. 50,000 times is a basic index of life test in our company, but the specific number of times and standard of test still need to be determined according to the specific application scenario of hinges and the environment of use.

    The instrument is used to record the performance indicators of the hinge during continuous use, such as the number of times it opens and closes, and its movement trajectory. Determine the number of tests to ensure that the hinge will not suffer from fatigue fracture and other phenomena during use. Generally speaking, the number of tests is determined according to specific application scenarios and use environments. Statistics and analysis of test data are carried out to determine the life and reliability of hinges.

  • Plating thickness test

    Test the plating thickncess of surface treatment

    Plating thickness testing is an inspection method used to assess the thickness of a thin film layer applied to the surface of a metallic or non-metallic object. Common methods of plating thickness testing include: Measuring the microstructure of the plating by observing the plating on the surface of a sample to assess the thickness. The thickness of the coating is an important parameter for evaluating the quality of the coating, and is one of the most important factors influencing the reliability as well as the service life of the product. Therefore, accurate measurement of plating thickness is very important for product manufacturing and use.

    Surface nickel plating refers to the coating of a nickel metal layer on the surface of a metal in order to improve the corrosion resistance, surface smoothness and hardness of the material. The nickel plating layer can effectively isolate the substrate from the external environment, thus reducing the interaction between the material and the corrosive medium and improving the corrosion resistance of the material. Nickel plating can make the metal surface bright, flawless, with a good sense of metal texture, improve the appearance of the aesthetic degree. Nickel plating can make the metal surface hardness increase, increase the anti-wear performance and wear resistance.
