Vulcanization is a process that utilizes time, pressure, and heat to create spliced O rings. The process begins with mating ends of the cord material in a splicing jig. After the ends are mated, the material is heated and subjected to a vulcanization process. The final result is an o-ring. Listed below are the advantages of each process.
Cold spliced o-rings
The process of vulcanizing O-rings uses adhesive, heat, and pressure to form a tight joint. The ends of a piece of cord material are placed in a special splicing jig. The o-ring is then removed from the splicing jig and cleaned of excess rubber before being vulcanized. The process is generally fast and accurate, and o-rings are often ready to use right away.
Cold spliced o-Rings are often made from aerospace-grade materials. They are customized to meet high-performance specifications and are great for smaller O-rings. This method is especially useful for low-durometer elastomers, and silicone sponge is commonly used. The material used in cold spliced o-rings is extruded from a cord.
Vulcanized o-rings
Vulcanized o-rings are ideal for applications that require static sealing. These o-rings are also ideal for low-volume orders and those that need to turn a product around quickly. Hot vulcanized o-rings are made using a variety of synthetic rubbers. They work well with low-volume parts, as well as molded parts, and are fast to provide.
The main application of vulcanized O-Rings is in the gasket, filtration, and storage tank industries. However, these o-rings are also applicable to any other flange sealing application. Whether you need to seal a rectangular container or a circular cylinder, vulcanized o-rings are an ideal solution. They can be made of a variety of materials, and are available in a variety of sizes, shapes, and materials.
Perfluoroelastomer o-rings
The advantages of perfluoroelastomer sliced o-rings over conventional ones are obvious. They offer the same performance characteristics as their corresponding standard materials, and they are available in quantities ranging from a single piece to thousands of pieces. In addition, spliced o-rings do not incur tooling costs, and they are available in a wide variety of rubber compounds. Moreover, they feature a proprietary vulcanizing technology that ensures a leak-free, strong splice.
Vulcanized o-rings can be made in any size and from a wide variety of elastomers. To manufacture these o-rings, a continuous cord is cut to the required diameter. Two ends of the cord are then joined together in a mould at high temperatures. This creates a strong molecular bond between the two cord ends.
