In the fields of high-end manufacturing and scientific research, precious materials require the most reliable "protective shield". Kinding vacuum storage tank is such an intelligent storage device specially designed for sensitive materials. It provides the highest level of protection for your products by creating an internal vacuum environment.
Outstanding sealing performance: In high-end manufacturing and scientific research fields, any minor contamination or quality fluctuation can cause incalculable losses. We adopt a unique double-sided welding technology and special sealing materials to ensure that the tank is completely sealed. The core mission of Kinding vacuum storage tank is to create an absolutely pure and stable vacuum environment for your precious materials. Our vacuum storage tank can maintain a vacuum state for a long time, effectively preventing outside air from entering and ensuring the purity of the materials. Each storage tank has been strictly inspected by precision instruments to ensure zero leakage.
A wide range of material options: In addition to high-quality conventional stainless steel, we also offer special materials such as 316L ultra-low carbon steel and Hastelloy. For special materials such as electronic-grade chemicals, we have developed a special inner lining technology to ensure that no impurities are generated during storage.
Convenient system connection: All interfaces adopt international common standards to ensure perfect integration with your other devices. We have also reserved multiple expansion interfaces to facilitate your functional upgrades based on future needs.

To ensure that we provide you with an absolutely reliable and zero-leakage vacuum environment, every Kinding vacuum storage tank follows a strict manufacturing process. We simplify the complex and explain its core process to you as follows:
Material precision milling and pretreatment: We control from the source. The selected plates will first undergo surface "milling" processing to ensure that the welding area is absolutely flat and smooth, laying a solid foundation for achieving a perfect seal.
| Precision laser cutting: | Utilizing high-precision laser cutting, it ensures that the dimensions of each component are exactly the same, guaranteeing a seamless fit from the very first step. |
| Numerical control plate rolling and forming: | Through a digitally controlled plate rolling machine, flat plates are precisely rolled into cylinders. We pursue extremely high roundness, which is not only for aesthetic purposes but also to evenly distribute stress and ensure structural stability. |
| Automated welding: | We use fully automatic welding equipment (such as TIG welding) for the main weld seam welding, which is precisely executed by the mechanical arm. This eliminates human fluctuations, ensuring that every inch of the weld seam is uniform, dense and aesthetically pleasing, fundamentally eliminating the risk of leakage. |
| Stress relief treatment: | Welding can generate internal stress. Through a dedicated annealing process, we gently release these "internal stresses", which greatly enhances the dimensional stability and long-term reliability of the equipment. |
| Inner surface mirror polishing: | The inner wall is polished to a high grade by a combination of mechanical and electrochemical methods, achieving a mirror-like effect with the highest Ra≤0.4μm. The smooth surface greatly reduces residue, precipitation and adsorption, making the cleaning extremely thorough and perfectly safeguarding the purity of the materials. |
| Ultimate helium mass spectrometry leak detection: | This is the ultimate test of our commitment to "zero leakage". In a dedicated vacuum chamber, the most sensitive helium mass spectrometry leak detector is used to conduct 100% inspection of the finished products. It can detect extremely tiny leaks, ensuring that your storage tank has excellent vacuum retention. |
| Clean packaging before leaving the factory: | Finally, after thorough cleaning, the storage tanks will be fully sealed with special dust-proof and moisture-proof materials to ensure that they can still arrive at your workshop in the cleanest state after transportation. |
| When using stainless steel vacuum storage tanks, please follow professional operation norms: |
Conduct a leakage test before use Operate strictly in accordance with the temperature rise and fall curve Regularly check the condition of the seals Establish a record file of vacuum degree changes |
Q: What is the maintenance time of the vacuum degree?
Under standard working conditions, the working vacuum degree can be maintained for more than 720 hours, and the specific duration depends on the usage conditions.
Q: Is the online cleaning function supported?
A: We can configure a dedicated vacuum CIP system to achieve online cleaning without disrupting the vacuum environment.
Q: How to verify vacuum performance?
A: Before leaving the factory, each device is provided with a complete vacuum performance test report, including the pumping curve and leakage rate detection data.
We understand that every industry has unique demands, and thus offer professional customization services to ensure that the equipment perfectly meets your process requirements.
