Two-die assembly for the extrusion of glasses with dissimilar thermal properties for fibre optic preforms
Two-die assembly for the extrusion of glasses with dissimilar thermal properties for fibre optic preforms
Extrusion of a preform based on core and cladding glasses with different thermal properties is demonstrated. The core glass (50BaO-8B) exhibits refractive index of 1.594 and softening temperature of 650 °C. Due to the softer nature of the core glass compared to the cladding glass, a novel two-die assembly method is employed for extrusion. The results show that the core glass flows through the cladding glass and be extruded first before stabilising to enable the extrusion of a cane of core and cladding glasses.

Abstract
Extrusion of a preform based on core and cladding glasses with different thermal properties is demonstrated. The core glass (50BaO-8B) exhibits refractive index of 1.594 and softening temperature of 650 °C. Due to the softer nature of the core glass compared to the cladding glass, a novel two-die assembly method is employed for extrusion. The results show that the core glass flows through the cladding glass and be extruded first before stabilising to enable the extrusion of a cane of core and cladding glasses.
