The difference between a rubber extruder and a weatherstrip extruder

Extruders commonly used for rubber hose 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 hoses distinct advantages, both in terms of surface quality and production efficiency. In contrast, conventional vented cold‑feed rubber extruders have longer screws, making them better suited for producing rubber products with more stringent material‑property requirements, such as sealing strips or round rubber profiles. 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‑structured screw design gives the resulting hoses distinct advantages, both in terms of surface quality and production efficiency.
Compared with pin‑type extruders, conventional vented cold‑feed rubber extruders feature longer screws, making them well suited for producing rubber products—such as sealing strips or round rubber profiles—that demand relatively stringent control over rubber properties. 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 equipment should be selected based on the characteristics of the product being manufactured—avoid making a choice without careful consideration.
