The invention relates to a tip plate for a bushing for receiving a high temperature melt, which tip plate comprises several sections of different type, while the invention further includes a corresponding bushing to produce glass fibres.

The present invention is a bushing for manufacturing a glass fiber that includes a base plate, a plurality of nozzles for discharging molten glass, and a nozzle group in which the plurality of nozzles are arranged in lines, being bonded to the base plate, wherein nozzles constituting at least one nozzle array among nozzle arrays of outermost layers of the nozzle group are plugged to a half or more of a nozzle length from a tip in depth. The glass-fiber-production bushing plate makes long-term, stable discharge of a uniform glass flow possible.

The present invention relates to a bushing for producing glass fibers, including: a base plate; and multiple nozzles from which molten glass is discharged, in which a nozzle group formed with the alignment of the multiple nozzles is joined to the base plate. In the present invention, a coating layer made of ceramics is formed on each of the nozzles forming at least a row of the outermost layer of the nozzle group. The coating layer does not cover the entire nozzle, that is, the nozzle is covered so as to be in a state of no coating layer in the vicinity of the nozzle tip. The present invention is a bushing plate for producing glass fibers, with which the occurrence of irregular phenomena is suppressed and a uniform glass flow can be obtained stably over a long period of time.

A spinner for use in manufacturing glass fibers includes a body having an upper wall with an opening therethrough, a lower wall, and a side wall extending between the upper wall and the lower wall. The side wall comprises a plurality of orifices, and the body comprises a metal alloy material and is formed using a localized welding method, such as a directed energy deposition (DED) method.

A method for producing glass fiber nozzles, comprising the steps of: A) providing or producing a base plate comprising a first material, being chemically resistant to the glass melt and dispersion strengthened, B) printing at least one tube made of a second material being chemically resistant to the glass melt onto one side of the base plate, wherein the at least one tube each comprise at least one feedthrough, C) generating at least one passage in the base plate, the passage is connected to at least one of the at least one feedthrough in such a way that each of the at least one passage through the base plate forms a common line permeable to the glass melt, with at least one of the at least one feedthrough of an associated tube leads through the base plate and through the associated tube.

The present one embodiment provides a method for manufacturing a bushing utilizing Cubic Boron Nitride (CBN) discs. The initial fabrication of the CBN discs involves selecting a suitable grain size of CBN powder, compacting the powder into a preliminary bushing shape, and sintering it at a sufficient temperature to bond the grains securely. Post-sintering, the CBN form is machined into the final bushing shape with precise tolerances. This method further includes forming holes in the CBN disc, assembling the discs into an array with the desired number of fibers, and creating a carrier to hold this array.
