In the industrial field, vacuum screws, as key fasteners to ensure stable vacuum environment of equipment, have strict requirements for material properties, production processes, and application scenarios. Shanghai Yaluo Precision Fastener Technology Co., Ltd., as a comprehensive and professional fastener&component enterprise, provides solid support for the high-quality supply of vacuum screws with its profound accumulation in the fields of special materials, multi standard production, and non-standard customization.
1、 Material performance: the "reliable cornerstone" in vacuum environment
Vacuum screws require long-term service in low-pressure and high cleanliness environments, and the choice of material directly determines their performance limit. Shanghai Yaluo Precision meets the requirements of vacuum working conditions and selects a variety of high-quality materials:
-Stainless steel series: Austenitic stainless steel (such as 304, 316L) has excellent corrosion resistance and oxidation resistance, which can effectively prevent metal ion precipitation in vacuum environment; Double phase stainless steel and super double phase stainless steel are superior in strength and corrosion resistance, and are suitable for high-pressure vacuum equipment; High temperature resistant stainless steel can withstand high temperature fluctuations in vacuum environments, ensuring the stability of screw structures.
-Special alloy series: Inconel alloy, Monel alloy, Hastelloy alloy, etc., have extremely strong corrosion resistance and high-temperature oxidation resistance, and can cope with extreme vacuum conditions such as nuclear power and chemical industry.
-Other materials: Titanium alloy materials are lightweight, strong, and have excellent corrosion resistance, and are widely used in aerospace vacuum equipment; Plastic and nylon materials can meet some vacuum scenarios with low load and extremely high cleanliness requirements, such as vacuum components for medical equipment.
These materials have undergone strict screening and performance testing by Shanghai Yaluo Precision, ensuring excellent mechanical properties, corrosion resistance, and airtightness in a vacuum environment, laying a solid foundation for the stable operation of vacuum equipment.
2、 Production Process: The "Craftsmanship of Precision Manufacturing"
The production process of vacuum screws directly affects their accuracy and sealing performance. With strong equipment organization capabilities and rich material production experience, Shanghai Yaluo Precision has created a set of precision production processes:
-Material processing: Customized heat treatment processes are adopted for different material characteristics, such as solid solution treatment of stainless steel and aging treatment of alloy materials, to optimize the internal structure of the material and improve its comprehensive performance.
-Precision machining: relying on advanced CNC machining equipment, high-precision machining is carried out on the threads, heads, and hollow structures of screws (if they are ventilated vacuum screws) to ensure dimensional tolerances are controlled at the micrometer level, ensuring the assembly accuracy and sealing performance of screws.
-Surface treatment: Choose the appropriate surface treatment process according to the application scenario, such as passivation treatment to enhance the corrosion resistance of stainless steel, coating treatment to improve the wear resistance and sealing of screws, ensuring their long-term use in a vacuum environment without failure.
-Quality inspection: Strictly following domestic and international standards such as GB, ISO, ANSI, etc., each batch of vacuum screws is subjected to multidimensional testing such as dimensional accuracy, mechanical properties, and airtightness. For example, helium mass spectrometer leak detector is used to detect the airtightness of screws to ensure their reliability in a vacuum environment.
In addition, Shanghai Yaluo Precision can flexibly adjust production processes, customize non-standard vacuum screws and mechanical components according to customer drawings or requirements, and meet the personalized needs of different industries.
3、 Application areas: Multi industry 'vacuum guarantors'
