Abstract
A plastic optical fiber dual extrusion die is disclosed. A core extrusion die is arranged in the hull extrusion die. The core material of the plastic optical fiber is input from the material inlet of core extrusion die and the hull material is input from the material inlet of the hull material extrusion die. The core material is extruded from the core extrusion die and the hull material is extruded from the hull extrusion die. After the core material and the hull material are extruded together, the hull material is glued onto the outskirt of the core material. The molding process is finished at one time and there is no need to dry. The utility model is simple in structure, simple in production technology, short in production period, low in cost of the raw material, low in production costs and stable in product quality. The utility model can be widely used for the polymerization reactor of the plastic optical fiber dual extrusion die.
