Side Feeders
A Side Feeder Barrel is used in rubber extrusion machines to introduce additional materials directly into the processing zone without disturbing main flow or pressure. Typically installed between the feed zone and compression zone, it allows controlled feeding of rubber compounds, fillers, carbon black, silica, additives, recycled material, or other processing enhancers. Designed to handle high viscosity rubber materials, the barrel ensures uniform mixing, consistent pressure, and improved output stability. With precision-machined grooves and high-strength alloy or bimetallic construction, it is engineered to withstand high torque, abrasive fillers, and elevated processing temperatures.
