FAQs
Whether it is stainless steel, aluminum, or titanium alloys, high vacuum chambers, and ultra-high vacuum chambers, or one-piece or welded chambers, from regular sizes to oversized products, we can meet any of your vacuum chamber requirements. We are equipped with a super-large CNC gantry machining center with a maximum stroke of 6500*4200*1800mm so that your design and products are no longer limited by processing capabilities and realize your higher pursuit of vacuum chambers.
We have a professional welding team led by former welding engineers from Applied Materials, who are proficient in various welding technologies for vacuum chambers, such as brazing, EBW, laser welding, argon arc welding, vacuum brazing, vacuum diffusion welding, and orbital welding. Different welding types correspond to different materials such as aluminum, stainless steel, and titanium, and your various requirements for vacuum chamber welding.
Friction Stir Welding (FSW) is an innovative and solid-state joining process. This technique is primarily used to join materials that are difficult to weld by traditional fusion methods, especially aluminum and other non-ferrous metals, though it has been successfully applied to steels, titanium, and even thermoplastics. We are proud to introduce to you our Asia-leading friction stir welding capabilities. The welding depth can reach 80-100mm.
Welding is fundamental to the construction, integrity, and functionality of vacuum chambers, ensuring they meet the stringent requirements of their intended applications. Welding plays a crucial role in the manufacturing and maintenance of vacuum chambers for several reasons.
Airtight Seals: The primary function of a vacuum chamber is to maintain a vacuum or a controlled atmosphere inside the chamber. Welding is essential for creating airtight seals that prevent air or gases from leaking into or out of the chamber. This ensures that the vacuum integrity is maintained, which is critical for the processes that the chamber is used for, such as in scientific research, aerospace, and semiconductor manufacturing.
Strength and Durability: Vacuum chambers need to withstand internal pressure differentials without deforming or breaking. Welding provides strong joins that can handle these stresses over the chamber’s operational life. This structural integrity is vital, especially for chambers used in high-pressure, high-temperature, or corrosive environments.
Material Compatibility: Vacuum chambers are often made from metals like stainless steel, aluminum, or titanium, which have low outgassing rates—a critical property for maintaining vacuum integrity. Welding techniques for these materials have been developed to ensure that the welds themselves do not become sources of gas leak or contamination.
Complex Shapes and Customization: Welding allows for the construction of chambers with complex shapes or custom configurations. This is important for scientific experiments or industrial processes that require unique chamber designs to accommodate specific equipment, samples, or processes.
Repair and Modification: Over time, vacuum chambers may require repair due to wear and tear or might need modifications to suit new processes or equipment. Welding is a versatile method that can be used for both repairing damages (like cracks or leaks) and making modifications (like adding new ports or changing the chamber size).
Minimizing Contamination: Proper welding techniques minimize the risk of contamination inside the chamber, which is crucial for processes that require high purity environments, such as semiconductor manufacturing or material science experiments.
Characteristics
Pressure Range:
Material Requirements: Materials used in HV and UHV systems must have low outgassing rates to minimize contamination and pressure increases. Common materials include stainless steel, aluminum, and ceramics. Surfaces are often electropolished to reduce gas absorption and desorption.
Sealing Techniques: Seals must prevent any air leakage into the vacuum. Metal seals are often preferred in UHV systems due to their lower outgassing rates compared to elastomeric seals.
Vacuum Pumps: Different types of vacuum pumps are used, often in combinations, to achieve and maintain the required vacuum levels. Turbomolecular and ion pumps are common in UHV applications, whereas rotary vane and diffusion pumps might be seen in HV setups.
Vacuum Measurement: Accurate measurement is critical. Ionization gauges are typically used in UHV conditions because of their sensitivity to extremely low pressures.
Application Scope
Semiconductor Manufacturing: HV and UHV environments are essential for semiconductor fabrication to prevent contamination that could lead to defects in microchips.
Surface Science: Studies involving the physical and chemical properties of surfaces often require UHV conditions to prevent contamination and to allow for the accurate measurement of surface interactions.
Particle Accelerators: Both HV and UHV are used in the operation of particle accelerators to minimize interactions between the particles and any residual gases, which can affect the quality of the experimental results.
Space Simulation Chambers: HV and UHV chambers are used to simulate the vacuum of space to test spacecraft components and sensors under conditions similar to those they will experience in orbit.
Nanotechnology: The fabrication and study of nanoscale materials and devices often require UHV conditions to ensure surface purity and to enable precise manipulation of atoms and molecules.
Electron Microscopy: UHV is crucial in some types of electron microscopes, which require vacuum conditions to prevent air molecules from interfering with the electron beam used to image samples.
Synchrotron Radiation Facilities: UHV conditions are necessary in these facilities to prevent the absorption or scattering of the generated synchrotron radiation by air molecules.

Deposition (e.g., physical vapor deposition, chemical vapor deposition), etching, and lithography. These processes require controlled environments to ensure high purity and precision in the layering and patterning of materials on silicon wafers.
In pharmaceutical manufacturing, vacuum chambers are used for freeze-drying (lyophilization) to remove moisture from substances, improving the stability and shelf life of pharmaceutical products without using heat, which could degrade the product.
Researchers use vacuum chambers to study the properties of materials under low-pressure conditions, which can reveal different behaviors and properties than at atmospheric pressure.
Simulate the vacuum of space to test spacecraft components and satellites, ensuring they can withstand the conditions they will face in orbit, including extreme temperatures and the absence of atmospheric pressure.
Used for applying thin films of materials onto substrates through techniques like sputtering or evaporation(PVD, CVD, FPD). This is critical in creating coatings for optics, electronics, and wear-resistant materials.
Vacuum chambers are used to remove gases from materials like plastics and resins used in automotive parts. This process helps in reducing defects and improving the quality and strength of the materials.
Vacuum chambers are typically constructed from materials that are non-outgassing and have low vapor pressures to maintain a stable vacuum environment. Common materials include:
