What is the difference between a rubber sealing strip extruder and a rubber hose extruder?

Extruders commonly used for rubber tube extrusion are pin‑type rubber extruders, which feature a screw barrel equipped with pins. These pin‑type extruders can thoroughly mix and pressurize the rubber within a relatively short screw length, effectively plasticizing and extruding it. The pin‑structured screw design gives the resulting rubber tubes distinct advantages, both in terms of surface quality and production efficiency. In contrast to pin‑type extruders, conventional vented cold‑feed rubber extruders have longer screws, making them well suited for producing rubber products—such as sealing strips or round rubber profiles—that demand stricter control over rubber properties. This is because vented extruders can evacuate air from the barrel, effectively addressing issues within the screw barrel…
Typically, the extruders used for rubber hose extrusion are pin‑type rubber extruders featuring a screw barrel with pins. These pin‑type extruders can thoroughly mix and pressurize the rubber within a relatively short screw length, effectively plasticizing and extruding it. The pin‑configured screw design gives the resulting hoses distinct advantages, both in terms of surface quality and production efficiency.
In contrast to pin‑type extruders, conventional vented cold‑feed rubber extruders feature longer screws, making them well suited for producing rubber products with relatively stringent material‑property requirements, such as sealing strips or round rubber profiles. This is because vented rubber extruders can evacuate air, effectively mitigating the adverse effects of residual gases trapped within the barrel on the final product.
Whether it’s a pin‑type rubber extruder or a conventional vented rubber extruder, the choice should be based on the characteristics of the product being manufactured—avoid selecting equipment indiscriminately.
