Check seal defects Improve surface quality instructions

Inspection of seal surface defects is important. Seals are a small industry in China's industrial production, and many people do not know much about seals. In fact, the seals are small, but they are used in conjunction with large-scale industrial equipment. The surface processing quality (mainly surface defects) directly determines the sealing and reliability of the equipment. In the industrial engineering production, the rubber seal is easily deformed and easily damaged. In the environment where leakage is not allowed, in order to ensure its quality, it is particularly important to perform quality inspection on the surface before use. Mainly for the detection of the annular surface of the seal, it is required to detect the defects and identify them.
