Product Description
Specifications and Dimensions Inner Diameter Range: It can be customized in various inner diameter sizes according to customer requirements, ranging from a few tenths of a millimeter to several meters. For example, non - standard O - rings with an inner diameter of about 1 millimeter may be used in precision instruments, while those with an inner diameter of several meters may be required in large - scale industrial equipment. Wire Diameter Size: The wire diameter is also customizable. Common wire diameters include 0.2 mm, 0.3 mm, 0.4 mm, etc. There are also thicker wire diameters for applications that require higher pressure resistance and larger sealing surfaces. Material Selection Nitrile Rubber: It has good oil resistance, wear resistance, and aging resistance. It is suitable for petroleum - based fuel systems and lubrication systems. The working temperature is generally between - 40ºC and 120ºC. Silicone Rubber: It has excellent high - temperature and low - temperature resistance. It can be used in the temperature range of - 60ºC to 200ºC. It also has good insulation and physiological inertness, and is often used in the electronic and electrical, food and medical industries. Fluororubber: It has excellent chemical corrosion resistance, high - temperature resistance, and oil resistance. It can maintain good performance at high temperatures above 200ºC. It is suitable for fields with high sealing requirements, such as aerospace and petrochemical. Performance Characteristics Good Sealing Performance: Relying on the elastic deformation of the rubber, it can closely adhere to the sealing surface to effectively prevent the leakage of liquids, gases, and other media. It can play an excellent sealing role in both static and dynamic sealing applications. Wear - Resistant: It has high hardness and strength, and can withstand a certain degree of friction and wear. It is not easy to be damaged during long - term use, ensuring the reliability of the seal. Chemical - Corrosion Resistant: According to different rubber materials, it can resist the erosion of various chemical media, such as acids, alkalis, salts, and organic solvents, and is suitable for different working environments. Application Areas Automotive Industry: It is used for the sealing of components such as the oil pan, cylinder head, transmission, and shock absorber of automobile engines to prevent the leakage of media such as oil, fuel, and refrigerant. Electronics and Electrical Industry: In electronic products such as mobile phones, tablets, and cameras, it is used for the waterproof, dust - proof, and shock - proof sealing of parts such as charging interfaces, headphone interfaces, and battery compartments. In the sealing of the shells of some electronic equipment, it can also play a role in shock absorption and buffering. Mechanical Industry: Non - standard O - rings are required for the sealing of parts such as hydraulic systems, pneumatic systems, and gearboxes of various mechanical equipment to ensure the normal operation and working efficiency of the systems. Production Process Mold Design and Manufacturing: According to the dimensions and requirements provided by customers, high - precision molds are designed and manufactured. The accuracy of the mold directly affects the dimensional accuracy and quality of non - standard O - rings. Rubber Mixing: The selected rubber raw materials and various additives are mixed and refined according to a certain formula to obtain the required properties, such as hardness, tensile strength, and aging resistance. Molding and Vulcanization: The mixed rubber is placed in the mold, and through high - temperature...
