65 Butyl Extruder

Today, cold-feed rubber extruders are widely used for extrusion molding, with many rubber products manufactured using this technology. Common types of rubber products include those made from EPDM (ethylene propylene diene monomer), silicone, and natural rubber. During extrusion, these materials are typically fed into the machine via a forced‑feed roller system, which pushes the compound into the extruder’s screw barrel where it is processed before being discharged through the die to form the final shape. However, certain rubbers—such as butyl rubber—are notably soft and highly adhesive. With conventional feeding methods, the material can easily break or tear during extrusion, preventing continuous feeding. To address this issue, we have developed a dual‑arm feeding extruder, which is particularly suited for processing butyl rubber. This type of extruder employs a dual‑arm, interlocking feed mechanism to forcibly convey the soft butyl rubber into the screw barrel, making it an ideal solution for producing butyl‑based products. For example, automotive vibration dampers are commonly manufactured using a dual‑arm‑fed butyl rubber extruder. Since different rubber compounds exhibit distinct properties, selecting the appropriate extruder based on the specific characteristics of your product is essential to achieving optimal results.

65 Butyl Extruder

Today, cold-feed rubber extruders are widely used for extrusion molding, and many rubber products are manufactured using this type of equipment. Common types of rubber products include: EPDM Products made from EPDM rubber, silicone rubber, and natural rubber all rely on a forced‑feed roller system during extrusion to ensure continuous material delivery. The rubber is fed through the feed block into the extruder’s screw barrel, where it is processed before being extruded and shaped at the die head. However, certain rubbers—such as butyl rubber—are notably soft and highly adhesive. With conventional feeding methods, this can easily cause the rubber sheet to break during extrusion, preventing uninterrupted material supply. To address this, we have developed a dual‑arm feeding extruder, which is particularly well suited for producing butyl rubber products. During operation, this machine employs a dual‑arm, interlocking feeding mechanism to forcibly feed the soft butyl rubber into the screw barrel, a method that is ideally tailored to butyl rubber processing. A common example is automotive vibration dampers, which are manufactured using a dual‑arm‑fed butyl rubber extruder. Given the varying properties of different rubber types, it is essential to select an extruder that matches your specific product requirements to achieve optimal results.
