The excellent performance of the premium vacuum tin starts with the strict selection and elaborate polishing of each selected material. Different from ordinary vacuum tins, we take "material determines quality and material selection builds high-end" as the core, select top-level raw materials in the industry, and match them with precision processing technology, so that every material detail shows high-end texture, balancing durability, safety and adaptability. It is suitable for high-standard scenarios such as high-end industrial production, precision laboratories and high-end food storage, and becomes the preferred vacuum storage and processing equipment in high-end fields.

　　The core material of the tank body is food-grade 316L stainless steel and aviation-grade corrosion-resistant alloy, which abandons the disadvantages of easy wear and corrosion of ordinary materials. The material purity is more than 99.9%, without any harmful impurities precipitated, and it has both super corrosion resistance and impact resistance. It can withstand complex media such as strong acids and alkalis, and will not rust or deform after long-term use, ensuring the purity and safety of stored materials, and is suitable for fields with high material requirements such as pharmaceuticals, high-end food and precision chemicals.

　　The sealing parts are made of imported fluororubber and silicone rubber composite materials, which are flexible and have extremely strong sealing performance. They have excellent high and low temperature resistance, and can work stably in the environment of -40℃ to 350℃ without aging or leakage. Combined with the precision sealing structure, the vacuum degree can be kept stable for a long time, effectively isolating air, moisture and impurities, and maximizing the retention of the original characteristics of materials. The inner wall of the tank is treated with mirror polishing technology, using food-grade polishing materials, which is smooth without dead corners, easy to clean and not easy to be contaminated, eliminating material residue and secondary pollution.

　　The auxiliary materials are high-strength engineering plastics and rust-proof hardware accessories. Every material has passed strict testing, complying with international environmental protection and safety standards, balancing light weight and load-bearing capacity. It is not only convenient for installation and transportation, but also can improve the overall service life of the equipment, making the premium vacuum tin not only have superior material performance, but also have long-term use value, winning trust with materials and establishing high-end with quality.
