Hebei Shida Seal Group’s line of co-extruded dual durometer rubber extrusions and seals fuses together a dense or rigid material, for strength of the attachment system, with a soft or flexible material, to complete the sealing function. Dual Durometer material capabilities include: EPDM Rubber (Dense & Sponge) and Plastic -Vinyl (Rigid & Flexible).
We are a custom manufacturer of dual durometer extrusions. Various products include channels, connectors, door gaskets, flanges, housings, seals, tubes, tapes and sponges. Capabilities include molding, bonding, engineering, packaging, product development, fabrication, contract manufacturing and designing. Automobile, construction, electrical, medical and transportation industries served.
Dense rubber is harder than sponge rubber and, therefore, most resistant to compression. Most dense rubber profiles range from under 30 duro to 90 duro Shore A, depending on their shape. At 40 duro, dense rubber profiles have the consistency of pencil erasers. At 90 duro, they are hard like hockey pucks. Under low temperature conditions, dense profiles become harder.
Sponge rubber can be shaped into various industrial rubber products, including dual durometer profiles. By combining sponge rubber and solid rubber into a single part (such as bulb trim seals), different areas of hardness are achieved. Typically, sponge profiles are characterized as soft, medium, and firm. Sponge rubber can be open cell or closed cell.
By joining two materials of different physical properties, structural integrity and flexible function can be combined into one part. For example, when a rubber gasket must be attached to a metal part to provide a closure seal, a dual durometer rubber extrusion combines both functions into one piece, which significantly reduces assembly costs while enhancing performance and function.
We always manufacture our dual durometer seals profiles extrusions from the highest quality compounds available. This ensures that our dual durometer seals profiles extrusions are not only suitable for use, but also made to last. Despite offering high strength and tear resistance, our rubber dual durometer seals profiles are also highly flexible. This enables our profiles to fit around a wide variety of curves.
Our facility is fully equipped with the latest equipment and technology, providing us with the capability to manufacture precision extruded dual durometer seals in quantities from short run to full production runs. We have 5 extrusion lines, continuous cure microwave, precision cutting, and splicing machines, and also provide value-added finishing services. In addition, we offer in-house tool, and mold design and manufacturing to ensure that your parts are manufactured to the most exacting requirements.
Hebei Shida Seal Group is uniquely qualified to manufacture EPDM dual durometer seals extrusions for your application. Our quality management system is IATF 16949:2016 accredited. We can provide PPAP Level 3 documents for OEM clients.
