Silicone O-Ring Seal
Silicone O-ring seals are widely used sealing components in various types of machinery, mainly designed to prevent the leakage of liquids or gases. Common applications include providing sealing and leak-proof functions in water pipes, automotive parts, electronic devices, household appliances, and food machinery.
The primary material used for these O-ring seals is silicone, also known as silicone rubber. Silicone is a special type of rubber with excellent resistance to high and low temperatures, weathering, radiation, and features superior electrical insulation properties. Additionally, silicone offers good biocompatibility and will not cause harm to the human body, making it ideal for use in medical equipment and food machinery.
Silicone O-rings are typically manufactured through compression molding or injection molding processes. In compression molding, silicone material is placed into a pre-made mold, then cured under heat and pressure. Injection molding involves injecting silicone material into a mold under high pressure, then curing and demolding to produce more precise and complex shapes.
