Pin 90 rubber tube extruder

Model XJ-75 XJ-90 XJ-120 Screw Diameter (mm) 75 90 120 Length-to-Diameter Ratio 14:1 14:1 14:1 Motor Power (kW) 37 55 110 Screw Speed 55 50 45 Output (kg/h) 80–120 100–300 300–600 Applications: The pin-type cold-feed rubber extruder is suitable for extruding hoses, inner tubes, tapes, sealing products, and other rubber goods. This type of extruder features pins mounted on the barrel, which engage with corresponding grooves in the screw. Thanks to these pins, the pin-type cold-feed extruder offers advantages such as high output, low temperature, reduced energy consumption, superior product uniformity, stable discharge, and minimal residual rubber left in the screw after shutdown. Overview of the Pin-Type Cold-Feed Extruder: Pin-type cold-feed extruders are increasingly widely used in the rubber industry. They differ significantly from conventional extruders and hot-feed extruders in both design and performance. By installing a number of pins along the barrel and incorporating annular grooves into the screw, this extruder ensures that the rubber material moves in multiple directions under the action of the pins. As a result, the material avoids forming lumps during cutting, leading to markedly improved quality compared to traditionally extruded rubber. The pin-type cold-feed extruder enhances the quality of rubber extrusion while reducing equipment investment and saving energy, delivering substantial economic benefits. With continuous technological advancements, innovative machine designs have been gradually introduced into the rubber manufacturing sector. For instance, pin-type cold-feed extruders are now commonly employed in tread extrusion and various types of rubber processing. Their application scope is extremely broad, and their adoption rate is rapidly increasing; they are also widely utilized in hose production. Increasingly, pin-type cold-feed rubber extruders are replacing hot-feed extruders, effectively improving product quality while conserving resources.

Purpose:

The pin‑type cold‑feed rubber extruder is well suited for extruding hoses, inner tubes, tapes, sealing products, and other rubber goods. This type of extruder features pins mounted on the barrel, which engage with corresponding grooves in the screw. Thanks to the action of these pins, the pin‑type cold‑feed extruder offers advantages such as high output, low processing temperatures, reduced energy consumption, superior product uniformity, stable discharge, and minimal residual rubber remaining in the screw after shutdown.

Overview of the pin-type cold-feed extruder:

Pin‑type cold‑feed extruders are increasingly widely used in the rubber industry. Compared with conventional extruders and hot‑feed extruders, they differ significantly in both their structural features and operational performance. Because this type of extruder is equipped with a certain number of pins within the barrel and incorporates annular grooves in the corresponding screw section, the rubber compound, as it is extruded, is directed in multiple directions under the action of these pins. Moreover, after being sheared, the compound does not form lumps. Consequently, the quality of the extrudate produced by this method is markedly superior to that obtained using traditional extrusion techniques.

The pin-type cold-feed extruder enhances the extrusion quality of rubber, reduces capital investment in equipment, and achieves significant energy savings, delivering substantial economic benefits.

With the continuous advancement of technology, the rubber manufacturing industry has gradually adopted innovative machine designs. For instance, pin‑type cold‑feed extruders are now widely used in tread extrusion and for virtually all types of rubber compounds. These extruders boast an exceptionally broad range of applications and have experienced rapid growth; they are also commonly employed in hose production. Increasingly, pin‑type cold‑feed rubber extruders are replacing hot‑feed extruders, not only enhancing product quality but also conserving resources.
