With the popularity of cars, more and more people have higher and higher requirements for the long-term reliability, stability and appearance of cars. The inspection of automobile parts is an important process in the process of automobile overhaul, which will directly affect the repair quality and cost of automobile. When testing these auto parts, X-ray testing equipment must be used. As one of the five conventional nondestructive testing methods, X-ray testing technology has been widely used in industry.

X-ray testing is a non-destructive testing method that uses the characteristics that X-ray can penetrate the material and attenuate in the material to find the defects. X-ray air holes and wire clamps can check the internal defects of metal and non-metallic materials and their products.

After the external environment is detected manually, the internal environment detection requires X-ray ray ray penetration, because the internal pores, cracks, shrinkage cavities and porosity cannot be observed with the naked eye. Using X-ray nondestructive testing, the X-ray wave is short, the energy is strong, and the density and thickness of the tested articles are different. Therefore, after the X-ray released by the X-ray testing equipment penetrates the tested articles, the absorption degree of the objects to the rays is also different, Finally, the number of X-rays reaching the fluorescent screen is also different. Through the imaging principle, different black-and-white images will be formed on the fluorescent screen. Next, we need to collect the image with the help of professional equipment, analyze and process the image, and finally get a clearer image.

Scope of auto parts testing products:

Automobile interior test, automobile exterior decoration test, automobile electronic product test, automobile VOC / ELV test, automobile pipeline system test, automobile lamp test, automobile harness connector.

Inspection items of auto parts:

Durability test, operability test, comfort test, strength and regulatory test, dimension measurement, stiffness test, clearance test, disassembly force, operation force, opening force, vibration resistance function durability test.

Appearance inspection of auto parts

1. Measure the size of automobile parts, and analyze and judge according to the product outline provided by the enterprise.

2. Appearance defect detection: such as obvious scratches, scratches and missing on the product. According to the image, we can judge whether the product has defects. However, it also depends on the pixel level of industrial cameras. Generally, the higher the pixel is, the more obvious the defect is.

3. If the surface is contaminated, the product can be identified.

4. Check the integrity of technical products, regardless of whether there is crack or leakage treatment in the product design of the enterprise.

In the process of automobile manufacturing, the production and casting process of automobile parts is very important. As the foundation of automobile industry, automobile parts are a necessary factor to support the sustainable and healthy development of automobile industry. Most enterprises are vigorously developing and innovating. As the basis of automobile, the independent innovation of parts and components must not be careless.
