Open-side feeder cylinder

所属分类: Barrel

The side-feed hopper is a specialized design for twin-screw extruders, featuring one or more openings on the barrel wall that allow solid or liquid additives to be introduced into the molten polymer during the extrusion process. This design enhances the flexibility of material addition and enables a wide range of processing functions. The location of the feed openings should be optimized based on the properties of the materials and the process requirements; they are typically positioned in the screw compression zone or the metering zone. The size of the openings must be determined according to the flow rate of the additive and the viscosity of the polymer melt, while ensuring tight sealing at the openings to prevent leakage and maintaining thermal compatibility between the additive and the molten polymer to avoid temperature gradients.
