Publication number: 20200109078Abstract: A method of producing a capillary tube from glass includes zonally softening a tubular preform having an outer diameter DOD, an inner diameter DID and a diameter ratio Drel—with Drel=DOD/DID—in a heating zone heated to a draw temperature Tdraw and drawing off continuously from the softened region a capillary strand having an outer diameter dAD, an inner diameter dID and a diameter ratio drel—with drel=dOD/dID—at a draw speed vdraw and cutting the capillary to length therefrom. For cost-effective production of a thick-walled capillary by drawing from a preform without strict requirements for the geometry and dimensional accuracy of the preform, the capillary bore is subjected in the heating zone to a shrinkage process based on the action of draw temperature Tdraw and surface tension, such that the diameter ratio drel of the capillary strand is adjusted to a value greater than the diameter ratio Drel of the preform by at least a factor of 5.Type: ApplicationFiled: October 9, 2019Publication date: April 9, 2020Applicant: Heraeus Quarzglas GmbH & Co.
