Rubber Vented Extruder
I. Product Description
A rubber vented extruder is an advanced equipment specifically used for producing various foamed or non-foamed rubber products, mainly for manufacturing rubber pipes, sheets, handles, sleeves, profiles, sealing strips, etc.
Core Features: The vented extruder is equipped with a special vent port in the middle of the barrel, which can effectively remove air and volatiles from the processed material, ensuring product quality and stable performance.
Main Components:
Motor System: Provides stable power output
Reducer: Adjusts speed and torque
Feeding Device: Ensures uniform material supply
Barrel and Screw: Core extrusion components
Die Head and Mold: Key components for product shaping
Temperature Control Device: Precisely controls processing temperature
Vacuum Pump System: Achieves efficient venting function
Electrical Control System: Fully automated control
Frame Structure: Stable equipment support
Screw Structure Features:
The vented extruder screw adopts a five-stage design:
Feeding Section: Initial material conveying and preheating
Compression Section: Material compaction and initial plasticization
Throttling Section: Uses shallow, constant pitch, constant depth threads to provide high shear force and stable conveying
Venting Section: Area for volatile and air removal
Extrusion Section: Final plasticization and shaping extrusion
