ABSTRACT:
A die (40) for extrusion of optical grade fibers has its hard insert (42) placed under compression within a sleeve (44). Sleeve (44) is provided with a tapered interior surface (50) which matches the tapered exterior surface (48) of the insert (42). A metal lubricating layer (60) is provided between the tapered surfaces. The insert is pressed in to obtain compressive prestressing thereof, and the lubricating metal diffuses at the tapered surfaces to lock the insert in the sleeve.
