Extruded rubber shapes are continuous profiles manufactured by forcing uncured rubber compounds through specially designed dies. The profiles are then cured to stabilize their dimensions and develop the required physical properties. Unlike molded rubber parts, which are produced as individual components, extrusions maintain the same cross-section along their length. This makes extrusion suitable for seals, […]
Choosing an extruded rubber manufacturer involves more than comparing unit prices. The supplier must translate a drawing or application requirement into a stable compound, workable die and repeatable production process. For standard cords or strips, sourcing may be relatively straightforward. Custom profiles introduce more variables: material formulation, die swell, curing, dimensional tolerances, splicing, cutting and […]
What Are Extruded Rubber Gaskets? Extruded rubber gaskets serve as continuous sealing solutions with a uniform cross-section. The extrusion process pushes uncured rubber through a die. This method produces long, uninterrupted lengths. These gaskets function as static seals between flat surfaces. They also work in dynamic settings. Engine parts and rotating shafts rely on them […]
Getting an accurate quote for custom rubber extrusions requires detailed specifications. Manufacturers need clear dimensions, proper tolerances, the correct material, and the exact quantity. Any special requirements also matter. Having this information ready streamlines the quoting process. It prevents delays and unexpected costs. Use this checklist as a guide before contacting a manufacturer. Collect each […]
Silicone rubber extrusions can be much more complex than simple tubes, cords, or rectangular strips. A custom profile may combine hollow chambers, sealing lips, mounting channels, ribs, grooves, compression bulbs, and locating features within a single continuous cross-section. The practical limit, however, is not determined by how complicated the CAD drawing looks. A profile must […]
EPDM rubber extrusion is a manufacturing process used to produce continuous rubber profiles for sealing, cushioning, insulation, weather protection, and edge protection. Because EPDM offers strong resistance to sunlight, ozone, water, and changing temperatures, it is widely used for both indoor and outdoor applications. The extrusion process allows manufacturers to create profiles with consistent cross-sectional […]
Rubber extrusion tolerances describe the acceptable range of variation in the size and shape of extruded rubber parts. These tolerances matter because even small changes can affect sealing, product fit, and overall quality. Tolerance requirements change based on the rubber material, the profile design, the extrusion process, and industry standards. Definition of Rubber Extrusion […]
Sponge rubber extrusions are flexible profiles made by shaping sponge-like rubber materials into continuous lengths. These products often use EPDM, Neoprene, or Silicone because these materials resist weather, moisture, and chemicals. Sponge rubber extrusions provide excellent sealing, cushioning, and insulation in many industries. Their soft structure allows them to compress and recover, which makes them […]
Choosing the correct rubber hardness is essential to the performance of extruded rubber seals. If the material is too soft, the seal may deform excessively, wear quickly, or fail to remain securely in place. If it is too hard, it may not compress enough to fill gaps or irregular surfaces. For most extruded rubber seals, […]
Self-adhesive rubber strips provide a convenient way to seal gaps, protect surfaces, reduce vibration, and prevent dust, air, or moisture from entering an enclosure. They combine a flexible rubber layer with pressure-sensitive adhesive, allowing them to be installed without separate glue or mechanical fasteners. These sealing strips are widely used on doors, windows, cabinets, vehicles, […]
