Glass Tube Forming
At Accu-Glass tubing and rod are formed by a very unique Direct Draw process. The material is continuously "pulled" from a vessel of molten glass. The advantage of this process over conventional "tank drawn" tubing is that a wide range of geometric shapes and very precise tolerances are achieved. Additional advantages are the ability to manufacture lower volume runs more economically, and a very short turn around time from order to shipment. The unique tooling utilized is designed and fabricated on site by Accu-Glass personnel to meet specific customer needs.
In addition to a broad array of shapes, permanent opal colors can be add ed to the glass to provide reflection backgrounds and identification striping. The process is controlled using SPC techniques and Windows-based software data collection is utilized to retain product history. AG is capable of producing OD's up to 6.00 mm with wall thicknesses as small as 7% of the nominal OD. Internal diameters can be as small as 25 microns with tolerances down to +/- 1 micron. The measurement methods used to achieve these extremely tight tolerances are diverse depending on the product application. These methods employ laser, optical, volumetric, and mass flow measurement technologies, many of which were developed by Accu-Glass. Dimensional tolerances of +/- 1 micron for internal diameters for small tubing can be achieved.
