Air-filled sealing ring: The air-filled sealing ring has now become an indispensable new type of sealing accessory in industrial sealing. With its unique inflation expansion sealing and pressure relief contraction working principle, as well as numerous advantages such as strong adaptability and high fault tolerance rate, it is widely used in various industries.
Firstly, it is widely used in the pharmaceutical and food industries, mainly for sterilization and disinfection cabinets, drying equipment, sealed and insulated doors, freeze-drying machines, isolators, transfer window door boxes, and food processing sealed boxes. The product can be made of food-grade silicone material, which is non-toxic, odorless, resistant to high temperatures and does not deteriorate easily, and can meet the sterile sealed production environment, preventing dust and bacteria from entering the equipment interior.
Secondly, it is most widely used in the vacuum purification equipment field. Vacuum boxes, negative pressure chambers, dust-free clean rooms, and soundproof sealed chambers all commonly use air-filled sealing components. Ordinary sealing strips cannot meet the requirements of negative pressure airtightness, while air-filled sealing rings can fill uneven gaps, providing a stronger sealing effect, and ensuring the stability of the equipment's vacuum degree.
Chemical dust removal and metallurgical mechanical equipment are also major application scenarios. Dust-proof sealed gates, pipe flanges, high-temperature furnace doors, and anti-corrosion reaction vessels are often in acidic and alkaline corrosive, large dust volume, and high-temperature harsh environments. The selected anti-corrosion rubber material can effectively resist chemical corrosion, be resistant to high temperatures and aging, and reduce equipment leakage and dust problems over the long term.
In addition, there are also cold chain storage, rail transit, special protective equipment, cold storage doors, protective and explosion-proof cabin doors, and large box inspection openings. The products have minimal switch wear and are suitable for long-term use in equipment with frequent opening and closing.
At the same time, our factory offers various special-shaped sealing frames and non-standard customized air bladder rubber strips, which can be adapted to various non-standard special mechanical equipment. The overall product has a wide range of application scope, strong versatility, and can solve different sealing problems in various industries. With excellent performance, it is gradually replacing traditional old sealing accessories and has a very broad future in industrial use.
Specialized customized types: The conventional standard sealing parts have limited specifications and cannot meet the needs of complex equipment usage. Specialized customized air-filled sealing components have emerged and are now widely used in various non-standard industrial equipment, with a very wide applicable range.
Specialized sealing products are mainly designed for special-shaped, irregular edges, and unconventional square or circular sealed equipment. The overall is molded integrally, without joint gaps, and the airtightness is more stable, eliminating the problem of air leakage and water seepage at the joint position.
In purification and dust-free equipment, various specialized isolation cabins, non-standard test boxes, special purification sealed doors and windows are widely used for maintaining negative pressure environments, blocking air circulation, and ensuring workshop cleanliness standards.
In the industrial chemical machinery field, special reaction tanks, special pipe interfaces, irregular inspection cabin doors, dust-proof special shells, etc., have complex working conditions and structures. Ordinary rubber strips cannot be installed and fit properly. Customized special-shaped sealing rings can be processed according to the equipment's curvature, corner dimensions, and perfectly fit the special installation slots, with excellent dust-proof, anti-corrosion, and sealing effects.
At the same time, it is also widely used in medical special equipment, experimental detection instruments, special protective devices, military sealed cabins, and automated non-standard machinery. The equipment has a unique shape and different sizes, all can be customized and processed according to the drawings and samples.
The manufacturer can match different rubber materials according to the customer's on-site conditions, gap size, and usage temperature, and the style and shape are not restricted. It can solve all difficult sealing problems and make up for the limitations of ordinary sealing accessories. Specialized customized sealing accessories are also the preferred sealing products for most high-end mechanical equipment at present.
Air bladder and oil bladder types: Rubber air bladders and rubber oil bladders belong to multi-functional rubber and plastic pressure-bearing products. Different from sealing products, they have high flexibility and strong airtight sealing performance. With excellent expansion and rebound performance, they are widely used in various industrial fields.
Rubber oil bladders are mainly used in hydraulic equipment, oil pressure storage, equipment oil storage buffering, and fluid storage compensation equipment. It can store various media such as oil and water for a long time. The rubber raw materials are resistant to oil and corrosion, and are not easily eroded or aged by liquids. It can balance the internal pressure of the cavity and buffer hydraulic fluctuations, ensuring the normal operation of mechanical equipment.
Various inflatable cushion airbags are widely used in mining machinery, metallurgical equipment, and automated extrusion devices. By using inflation expansion to generate compressive force, they can achieve functions such as material compression, buffering and vibration reduction, and gap support. They can also buffer the vibration losses generated by equipment operation and reduce mechanical wear.
At the same time, airbag products are also widely used in dust removal sealing, pipeline sealing, ship protection, bridge buffering and vibration reduction scenarios. They are tough and resistant to pulling, have excellent pressure-bearing capacity, are resistant to wear and do not rupture easily, and can adapt to harsh outdoor and complex industrial conditions.
All our airbag and oil bag products can support non-standard special-shaped customization. Multiple rubber materials are available for selection. The overall is formed by one-step vulcanization, without air leakage or liquid seepage. The product specifications are complete, the workmanship is solid and durable, and they are suitable for many industries such as hydraulic equipment, heavy machinery, chemical transportation, road and bridge engineering, etc. They have wide applications and strong practicality, and can meet customers' various pressure-bearing, liquid storage and buffering usage needs.
