2、 Strict quality control technology system
（1） Material testing technology
Lifei Company has extremely strict control over the quality of raw materials. Advanced material testing technology is used for comprehensive inspection when each batch of raw materials enters the factory. For example, for stainless steel materials, a spectral analyzer is used to accurately analyze their chemical composition to ensure that they meet the corresponding standard requirements. For example, the content of major alloying elements such as chromium and nickel in 304 stainless steel must be within the specified range. At the same time, the hardness of the material is tested using a hardness tester to ensure that the material has appropriate mechanical properties. Observe the microstructure of the material through a metallographic microscope to determine whether there are defects such as inclusions and segregation in the material. Only raw materials that have passed all these strict inspections will be allowed to enter the production process, ensuring product quality from the source.
（2） Quality monitoring technology for production process
During the production and manufacturing process of the product, Lifei Company utilizes a series of advanced quality monitoring technologies. For example, in the mechanical processing stage, high-precision CNC machining equipment is used, which is equipped with advanced tool path monitoring systems that can monitor the running status of the tools in real time to ensure that the machining accuracy meets the design requirements. In terms of welding process, a welding quality monitor is used to monitor and record real-time parameters such as welding current, voltage, and welding speed to ensure the stability of welding quality. At the same time, through non-destructive testing techniques such as ultrasonic testing, radiographic testing, etc., welding joints are comprehensively inspected to promptly detect and eliminate welding defects, ensuring the overall quality of the product.
（3） Product performance testing technology
Every product undergoes strict performance testing before leaving the factory. For filter products, filtration efficiency testing will be conducted on a test bench that simulates actual operating conditions. By injecting a fluid containing a certain concentration of impurity particles into the testing system and detecting the content of impurity particles in the fluid after passing through the filter, the filtration efficiency of the filter can be accurately calculated. For valve products, pressure testing, sealing performance testing, etc. will be conducted. In pressure testing, the valve is installed on specialized pressure testing equipment, gradually increasing the pressure to detect the working state of the valve under different pressure conditions, ensuring that it can withstand the design pressure. In the sealing performance test, high-precision detection equipment such as helium mass spectrometer leak detector is used to detect the sealing part of the valve, ensuring that the valve has no leakage and meets the quality standards of the relevant industry.
