Sharing example for product application fields
1. Rubber automotive connector O rings and seals
The critical to achieve the airtight performance of automotive connectors lies in sealing O rings and Seals. It is not only for O-rings seals to fix different hole positions, but also deliver exceptional sealing effectiveness—thus ensuring the stable operation of automotive equipment and maintaining excellent waterproof performance. The primary material for manufacturing sealing O rings and seals is silicone rubber, which is formed through a chemical reaction between liquid silicone and solid silicone.
Silicone rubber as the core material for sealing rings with a variety of outstanding properties. Its excellent weather resistance, oil resistance and chemical resistance highly suitable for application in automotive power systems. In addition, silicone rubber features superior elasticity and temperature resistance, enabling it to adapt to the diverse and complex operating environments of automobiles, and ensuring the stability and reliability of automotive connectors under extreme conditions.
2. Kitchen and Bathroom supplies food-grade silicone rubber O rings and seals
A pressure cooker’s O-rings and seals have the important functions including airtight sealing protection, leak protection, explosion protection and safe pressure relief.
Airtight sealing protection: O-rings and seals are the key components of a pressure cooker; their primary function is to prevent water vapor from leaking out of the pressure cooker, maintaining high-pressure environment inside. The airtight performance directly affects cooking efficiency and safety. If O rings and seals become deteriorated, damaged or go missing, it will lead to steam leakage, insufficient internal pressure, failure to operate normally, and even a complete loss of usability.
Leak Protection: Sealing O-rings and seals maintain a high pressure environment inside a pressure cooker, effectively locking the juices and nutrients of the food, preventing moisture loss during the cooking process. Meanwhile, it prevents water vapor from leaking into the kitchen, reducing the cleaning workload and keeping the cooking place neat and tidy.
Explosion Protection: When a pressure cooker is in operation, the pressure generated by water vapor inside is extremely high, if sealing O rings and seals become deteriorated or damaged, their airtight performance will be compromised, which lead explosion risks. In the event of an explosion, high-pressure steam and hot water will erupt violently and splash everywhere. This poses a severe threat to people safety. Therefore, the integrity of sealing O rings and seals are one of the critical factors for ensuring the safe operation of a pressure cooker.
Safe pressure relief: Sealing O-rings and seals are generally designed with a specific gap for the purpose of safe pressure relief. When the internal pressure exceeds safety valve’s preset value, water vapor will be discharged through the gap, preventing pressure buildup that lead to an explosion, This design works with safety valve form a dual safety system, which enhances the overall safety performance of the pressure cooker. For instance, if the safety valve malfunctions, sealing O rings and seals pressure relief gap still perform its critical function and prevent accidents from occurring.
Through the synergistic operation of their multiple functions, sealing O rings and seals not only ensure pressure cooking efficiency, but also guarantee safety during operation. For daily use, it is necessary to conduct routine inspections of sealing components. Deteriorated or damaged parts should be replaced promptly to maintain the normal functionality of the pressure cooker.
