ABSTRACT:
A die (10, 40) for extrusion of optical grade fibers includes an insert (12, 42) placed under compression within a sleeve (14, 44). Tapered surfaces (18, 20 & 48, 50) between the insert and the sleeve enable axial assembly of the components when the insert is forced within the sleeve. Lubrication and interlocking between the components comprise either general lubricant and an interlocking ring (30) residing within grooves (26, 28) in the tapered surfaces, or a metal (60) which provides first a lubrication during assembly of the components and then a metallurgical diffusion bond therebetween.
