Automotive endoscopes used in surface defect detection of aluminum castings

Sep 8,2020
After more than 100 years of development, cars have become inseparable from the lives of modern people. Among the various parts of the automobile, castings are an important part of the automobile, from the chassis of the automobile to the engine, structural parts and safety parts, which are closely related to the production of die casting technology. Automobile castings contain very important engine blocks and cylinder heads, which gives the casting molding process a great advantage.

However, due to different processes and materials, temperature, gas, water vapor, environment or other factors in the manufacturing process may cause shrinkage, porosity, cracks, pores, sand holes, slag inclusions, etc. These defects may adversely affect the product, thereby affecting its service life, such as possible defects.

In the process of quality inspection of automobile castings, industrial endoscopes need to observe the internal conditions of some small holes or possible defects in the inner cavity of the casting, especially the internal curved channels. Common methods are difficult to implement.
The electronic video endoscope that uses a small image sensor for photoelectric conversion has high reliability and long life. Industrial endoscopes can be used to detect defects on the inner surface of castings. As a visual non-destructive inspection tool, it has intuitive visibility, clear images, omni-directional manipulation, light weight and portability, and can effectively expand the observation distance of the human eye. Inaccessible it is widely used in the manufacture and manufacture of automotive parts, such as internal inspection of exhaust pipes and internal defect detection of various castings.

Automobile endoscopes are mainly used to detect the condition of small-diameter channels in certain automobile castings. Small-diameter endoscopes with probe diameters of 2mm and 2.8mm have excellent imaging effects and relatively high light intensity. You can directly inspect the fine surface defects inside aluminum castings.

Our automotive endoscope camera can be used to regularly check the internal parts of the car parts for cracks or pigmentation. The measured holes are bent and the minimum diameter is 4MM, which cannot be directly observed by ordinary tests.
