Abstract
A bushing plate for use in the production of glass fibers has an array of nozzle tips. The bushing plate is formed by successive cold forming operations from a starting plate of precious metal alloy. The starting plate is first indexed through a press which coins embossments raised from one side of the plate. The plate is then indexed through another press in which bores are extruded through the embossments to form the nozzle tips. The ends of the tips are then finished in an operation such as EDM wire finishing.
