Sealing Rings and Overmolded Rubber Gaskets

In applications where specific sealing is required, metal inserts (e.g., stainless steel) or plastic substrates serve both a structural and practical function, ensuring the necessary structural rigidity required for the end-use application. At New Rubber, we have been active in the rubber molding and overmolding industry for over 45 years. Leveraging this extensive experience, the company has adopted innovative organizational and production processes, distinguishing itself through a commitment to Research and Development. This allows us to offer our customers even more advanced and efficient overmolding services.

Advantages of Rubber-to-Metal Overmolding

• Bonding and Durability: The process ensures a stable and long-lasting bond between rubber and metal, thanks to the chemical and/or mechanical bonding that develops during processing.
• Structural Integrity: The metal provides robustness and structural strength, ensuring dimensional precision and stability under mechanical stress. Meanwhile, the rubber provides elasticity, flexibility, shock and vibration absorption, and effective sealing.
• Design Flexibility: The process allows for the creation of complex geometries, the integration of technical elements, and the use of diverse materials to enhance functional performance.

In general, its adaptability allows for the development of customized solutions suitable for a wide range of industries and operating conditions.

Examples of Applications across Industrial Sectors:

• Railway: Precision valves (such as those used in braking systems), bushings.
• Water Treatment: Valves, membranes, and sealing systems.
• Gravimetric Dosing Systems: Scrapers, stop buffers.
• Food & Pharmaceutical Industry: Grippers for vial/product handling.
