We aim to provide insights into how these tailored products can address and solve your unique sealing needs.

Vulcanized O-Rings

Vulcanized o-rings are made of cut cord stock with both ends fused together to form a continuous loop. The vulcanization process involves applying a liquid form of uncured rubber to the cord ends, which are then joined in a heated mold. Applying heat and pressure triggers the curing of the material, resulting in a robust and seamless bond. This fusion creates cross-links between the rubber molecules, enhancing the o-ring’s mechanical properties and ensuring its integrity in sealing applications.

Due to their exceptional sealing capabilities in static applications, vulcanized o-rings are ideal for various settings. These include fluid or gas containment in the automotive and manufacturing industries. The strength of the bond and the quality of materials used make these o-rings exceptionally reliable in environments where a secure seal is paramount and a nonstandard size is required.

At Global O-Ring and Seal, customization is critical in our vulcanization process. We offer over 500 combinations of profiles, cross-sections, materials, durometers, and colors. By stocking over 1 million feet of cord stock, we produce vulcanized o-rings tailored to specific industrial needs. This wide selection ensures that regardless of the application’s chemical, thermal, or mechanical demands, we can fabricate an o-ring that meets those requirements. Additionally, there are two cord-cutting methods available to choose from: butt cut for a straight 90º cut angle or bevel cut at a 45º angle, which increases surface area contact and tensile strength, enhancing the seal’s effectiveness and durability.

Each vulcanized o-ring undergoes rigorous inspection before it leaves our facility. Our quality control process includes stretching routine samples to failure and recording tensile strength, breaking force, and ultimate elongation to continuously refine our vulcanization techniques. We ensure that every ring meets and exceeds industry standards for fit, finish, and performance, providing our clients with the highest-quality products possible.

Custom Molded O-Rings

Molding is a fabrication process used to shape rubber into o-rings by applying heat and pressure in a mold. This technique allows for precise control over the shape and size of the o-ring, making it ideal for applications requiring specific dimensional tolerances and geometrical intricacies that are not standard. The advantages of molded o-rings included enhanced uniformity, material efficiency, and the ability to produce complex shapes that are difficult or impossible to achieve with other methods.

At Global O-Ring and Seal, we offer two primary molding techniques for custom o-rings:

Compression Molding: This traditional rubber molding technique involves placing a pre-measured amount of raw material directly into the open mold cavity, which is then closed and heated. Under heat and pressure, the material conforms to the shape of the mold, curing it into a solidified form.
Continuous Molding: Unlike traditional molding processes, which produce individual parts, continuous molding creates long lengths of uniform cross-section products that can be cut to size. This method involves extruding the rubber components through a die and continuously curing them in a heated tunnel or through microwave processing.

The selection of material for custom molded o-rings is pivotal, as it determines the o-ring’s compatibility with the application environment, including exposure to chemicals, extreme temperatures, and mechanical stresses. Options at Global O-Ring and Seal include a variety of rubbers and elastomers, each offering different properties such as resistance to compression set, heat, and chemicals. Proper material selection ensures the o-ring performs optimally throughout its operational lifespan. Further customization options include varying the durometer (hardness), adjusting the material composition for enhanced chemical resistance or temperature tolerances, and selecting specific ID sizes and cross-sectional profiles to match unique sealing needs.

Both compression and continuous molding are suitable for static and dynamic applications. However, the choice between these techniques often depends on the volume and size requirements:

Compression Molding: This method is ideal for high volumes, usually over 750 units, of small to medium non-standard sizes, benefiting from economies of scale. Compression molding is efficient and cost-effective when the demand justifies the initial tooling expense.
Continuous Molding: This process excels for large, non-standard sizes and does not require specific tooling, making it cost-effective for lower volumes (fewer than 100 units). It’s particularly suitable for dynamic applications where flexibility and durability are critical, such as in high-pressure or vacuum environments.

By understanding these distinctions and options, one can make informed decisions about the best custom-molded o-ring solutions for their specific needs.

Custom Rubber Products

Custom rubber products encompass various items specifically tailored to meet unique industrial requirements. These products are not standard stock items but are designed and manufactured based on specific customer specifications. Examples include specialized seals, gaskets, and other molded components that must fit unique machinery or perform under particular conditions.

Creating custom rubber products is highly collaborative and tailored to each customer’s specific needs. It generally involves the following steps:

Initial Request: Customers provide a sample, drawing, or dimensions of the part they need, along with specifications such as material, color, and hardness.
Quotation and Setup: Global O-Ring and Seal evaluates the requirements and provides a quote, which may include a one-time setup fee for new designs.
Prototype Development: We create the first article sample for customer review and approval upon order confirmation.
Production and Delivery: Once the samples are approved, full-scale production begins, with the final products shipped according to the customer’s schedule.

Custom rubber products are essential in numerous industries where standard solutions cannot meet the unique operational demands. Key sectors include:

Automotive: Custom seals and gaskets for engine and transmission systems.
Oil and Gas: Specialized seals that resist harsh chemicals and fluctuating pressures.
Medical: Components that meet strict hygiene and compliance standards.

By providing bespoke solutions through custom rubber products, Global O-Ring and Seal ensures that even the most challenging and specialized requirements are met with precision and quality. This enhances the performance and reliability of customer equipment, simplifies the procurement process, and makes the customization process efficient and customer-friendly.

Custom Sealing Kits
