Product Overview
Our rubber extruder equipment is engineered for high-performance applications in rubber machinery, specifically designed for extruding tread, inner tubes, rubber tubes, and various rubber strips. The equipment operates with exceptional efficiency, utilizing a screw extruder mechanism that stirs, mixes, and plasticizes rubber materials before directing them toward the machine head for precise product extrusion through the die head.
This rubber extruder is particularly effective for producing rubber seals, featuring vacuum pump capability to eliminate bubble formation during production. It is extensively used in styrofoam strip manufacturing. The Pin rubber extruder variant, designed for hose extrusion, incorporates multiple rows of pin barrel screws that ensure optimal pressure ratios, resulting in superior product quality and enhanced aesthetic appearance.
