Sealing with pressure is a common technology in industrial production to ensure the sealing performance of products. In the production process, we often need to test and quality control the pressure sealing to ensure the quality of the product. Below I will introduce the detection and quality control methods of pressure sealing in detail:

1. Visual inspection: First of all, the worker can confirm whether there are obvious defects or problems in the pressure sealing through visual inspection, such as cracks, deformation, etc., and whether the seal is completely close. This is a simple and commonly used method to quickly spot obvious quality problems.

2. Air tightness test: air tightness test is a common pressure sealing detection method, by applying a certain gas pressure at the sealing place, and then observing the pressure change to detect the sealing performance of the sealing. If the pressure changes greatly or continues to drop, it indicates that there is a leakage problem in the plugging and further treatment is needed.

3. Pressure testing: For some products that need to withstand high pressure environments, pressure testing is an indispensable step. By applying high pressure to the sealing place, observe the deformation of the sealing and whether there is leakage to ensure the stability of the product in the high pressure environment.

4. X-ray testing: For some high-demand products, such as medical devices or aerospace components, X-ray testing technology can be used for non-destructive testing of the plugging to ensure that its internal structure and sealing performance meet the requirements.

5. Quality recording and tracking: For each sealing process, quality recording and tracking should be done, including the sealing material, process parameters, test results and other information, so as to be able to trace and locate the problem in time when quality problems occur, and take corresponding improvement measures.

In the production process of pressure sealing, strict implementation of the above detection and quality control methods can effectively ensure the sealing performance and quality stability of the product, and improve the reliability and stability of the product.
