- Glass fiber bushings
- with TIG-welded tips
- with laser-welded tips
- Basalt fiber bushings
Bushings for extreme thermal and corrosive conditions, such as those encountered for example in processing molten basalt, S-glass and mineral glasses.
Individual design for the perfect process
The first glass fibers were manufactured in Hamburg by W. von Paczinsky in 1908 using a bushing. Industrial production started in the USA in 1930 and in Germany in 1939, initially using 51-, 102- and 204-tip bushings. Heraeus has been producing glass fiber bushings since 1970. The designs have been continually optimized and, by reducing the spacing, the number of tips has been increased to 4000 and more. To meet customer requirements, bushings can be made both for the two-step process, in which glass pellets are melted on a perforated sheet and subsequently drawn to fibers, and for the single-step process, in which pre-melted glass is fed into the bushing. We would be pleased to assist you in continually optimizing your system.
