Glass processing - Import export

Finest quality surface polishing is vital in plane optic production. At Befort, this has top priority from production all the way to final inspection. Thanks to sophisticated CNC technology, we are able to produce single planeoptic components as well as multifunctional systems. We process optical glass, filter glass, quartz glass and float glass up to a size of 600 mm diameter. We make filters, groundglass screens, plane mirrors, windows with a plane parallel surface contour and realize customized solutions for specific applications. In our test laboratory we measure machined surfaces with an interferometer to be able to guarantee top optical quality! No lens element leaves our factory before it meets the exact specifications and requirements of the customer

The cross-sections of multi-channel capillaries consist of a large number of single holes, which are either in a random order or neatly arranged. Depending on the application in which these capillaries are used they can fulfill several tasks. Materials Soda-lime glass (AR, I860, PH360 etc.) Borosilicate glass (DURAN©, PYREX©, SIMAX© etc.) Aluminum silicate glass (Schott 8252/8253) Process of Production Two different production methods are used to manufacture multi-channel capillaries: 1. Production from a preform Prior to drawing the capillary several performs are mounted and joined together. During this process the channels are created from a single capillary. Hollow spaces are then filled with glass rods and are evacuated with heat. All unintended side channels and hollow spaces between the capillaries are sealed during this process and result in a closed cross-section, which is only punctuated with the inner geometry of the single capillaries. Reproducible profile sizes,...

This compact micro torch is ideally suited for melting the ends of sample tubes precisely and safely. As a very small flame can be adjusted, it is possible to melt the capillary precisely at a defined point without excessively heating the remaining capillary, as is the case with standard torches. The torch is operated with a hydrogen/oxygen or a propane/oxygen mixture, both of which provide a very hot flame that even permits quartz glass to be processed. This torch is an extremely versatile tool with which practically all types of glass can be processed – from simple flaming to highly complex tasks. Features of the micro torch Fine, concentrated needle-point flame High heating capacity Mixed-gas operation Two separate needle valves Complete with fine nozzles Torch length >130 mm (without nozzle) Operating principle The torch consists of a gas mixing chamber and two gas inlets, which are also suitable for aggressive media such as hydrogen and oxygen. Two needle valves at the...

Our patented Spear nozzles with thermal-sealing via the separate tip-heater open up new possibilities in injection molding, especially when processing glass fiber or carbon fiber reinforced resins.
