Bonded Plate Seals

At Micro-Tronics, Inc. (MTI), we specialize in the application engineering of precision rubber components. Armed with extensive manufacturing experience, highly skilled engineering and manufacturing experts, state-of-art manufacturing equipment, and a broad selection of rubber materials, we have what it takes to produce high-quality molded rubber parts and products for a range of industries and applications. One of our core competencies is rubber molding, which enables us to make rubber-to-metal bonded seals.

Rubber-to-metal bonded plate seals are used to separate and isolate sections of fluid assemblies. They consist of metal rings, plates, or other geometries with molded, elastomer seals around their circumferences. The metal structure provides support and ensures pressure is evenly distributed along the seal surface, which increases the reliability and decreases the risk of damage. The elastomer allows for the creation of a strong seal under pressure, which protects systems against the egress of fluids and the ingress of contaminants. These qualities make elastomer seals ideal for use in various industrial and mechanical systems. 

Below, we provide an overview of our bonded seal capabilities. 

Our Bonded Plate Seal Capabilities

The team at MTI offers turnkey solutions for our customers; our in-house machine shop and full scope of services reduces lead time for our customers’ components, prevents handling issues, and allows us to hold tighter flatness tolerances. 

We offer rubber-to-metal bonding services for components in a variety of shapes and sizes. We can create seal plates, valves, and other metal components with seal beads as well as vibration isolators, gaskets, and other fully or partially encapsulated components. We can also mold solid elastomer parts and products, such as boots, bumpers, isolators, grommets, and more. We can also repurpose pre-existing plates; we can remove old elastomers and adhesive from the plates and replace them with new rubber and adhesive.

Our facility houses rubber molding equipment with pressure capacities ranging from 30 to 400 tons and platen sizes up to 24 inches by 24 inches. While the work envelope depends on the configuration of the part or product, the equipment has the capabilities to process most elastomer components. As a result, we can create bonded seals suitable for closing fluid systems used in virtually any industry or application. 

Our application engineering team can work with your pre-existing or conceptual designs to ensure they are designed for manufacturing. This assistance can include confirming the right manufacturing processes, tooling, and materials for your components. We can also assist with choosing the right adhesive and process for bonding your desired elastomers and metal components.

Bonded Plate Seal Materials

Both the metal ring component and the rubber component of bonded seals can be made from a variety of materials to suit different sealing applications. For example, the ring can be made from aluminum, brass, or stainless steel, while the elastomer seal can be made from EPDM, nitrile, silicone, or Viton. We can also accommodate non-metallic plates, such as plastic substrates. 

At MTI, we can utilize our proprietary rubber formulations and many of these formulations meet AMS, MIL and NSF specifications. These formulations can consist of combinations of the following materials:

  • Silicone
  • Nitrile
  • EPDM
  • Fluorocarbon aka Viton
  • Fluorosilicone
  • Neoprene
  • Kapton
