Where can I find a factory to customize vacuum box inflatable sealing rings? Look no further than Qingtu Rubber. With 18 years of industry experience, Qingtu Rubber is a leader in the domestic inflatable sealing ring industry, offering professional silicone inflatable rings.
1. The interior of the box is made of mirror stainless steel or brushed steel by argon arc welding, while the exterior shell is coated with high-quality cold-rolled steel plate through electrostatic spraying, featuring an aesthetically pleasing and innovative design.
2. The thermal insulation system uses ultra-fine glass fiber to fill the insulation area, and non-metallic high-temperature-resistant materials are used at the connection points of the inner and outer shells, effectively reducing temperature conduction.
3. The circuit system is equipped with a swing-open door for easy maintenance and inspection.
4. The box door tension is adjustable, utilizing the advanced third-generation inflatable seal technology, ensuring long-lasting and effective high vacuum inside the box.
5. Storage, heating, testing, and drying are all carried out in an oxygen-free environment, hence no oxidation occurs.
6. Rectangular workshop, maximizing the usable volume.
7. Tempered and bulletproof double-glazed doors provide a clear view of the objects within the observation room.

8. Microcomputer temperature controller with timing function, precise and reliable temperature control.

Vacuum Box Core Component - Inflatable Seal Ring Product Performance
Silicone materials offer excellent sealing properties, high-temperature and weather resistance, anti-aging, shockproof, and waterproof capabilities, and can adhere to various smooth surface materials.
2. High strength, long service life, product is environmentally friendly and insulated, withstands extreme temperatures, compression, acid and alkali resistance, anti-aging, and UV radiation.
3. Excellent non-stick surface property.
4. Made from 100% high-quality silicone material, rigorously tested, and meets environmental standards.
5. High Temperature Resistance: -70°C to 300°C
6. Heat Resistance: Silicone rubber boasts superior heat resistance compared to standard rubber, allowing for almost indefinite use without performance degradation at 150 degrees; continuous use for 10,000 hours at 200 degrees; and it can also withstand temperatures up to 350 degrees for a period of time.
7. Weatherability: Normal rubber degrades quickly under the action of ozone produced by corona discharge, whereas silicone rubber is unaffected by ozone. Additionally, its physical properties remain almost unchanged over a long period of time in UV and other weather conditions.
8. Anti-aging, corrosion-resistant, silicone itself has a strong inertness.


Shanghai Qingtu Technology Co., Ltd. is a specialized manufacturer of vacuum box inflatable sealing rings. We can produce large-scale inflatable sealing rings with a circumference of 5 to 10 meters using small molds. This not only significantly reduces the mold investment cost but also makes the serialization development of inflatable sealing products a reality. A single mold can produce inflatable sealing rings (units) with any circumference size while maintaining the same cross-sectional dimensions. The use of inflatable sealing rings greatly saves customers' R&D costs and resolves the issue of poor sealing in large-scale equipment that has plagued the industry for years. With years of experience in producing silicone inflatable sealing rings, our product quality and company strength have been consistently recognized by customers. We are a professional factory for silicone inflatable rings.
