Rod & Taper Drawing
FTI uses a straight line draw tower to manufacture optical rod, multirod, and image conduit. Set up in 1992, this machine has the capability of producing rod diameters from .060 (1.5mm) to 1" (25mm) in diameter, in continuous lengths up to 92" (2.34M).
Standard glass systems, as well as the black glass system prized for dental curing applications, are produced on this equipment.
Grade of finish, perpendicularity, and length tolerances can be specified by the customer.
If we have the glass system in house, a short run or first release parts are normally shipped within 5 days.
FTI uses a proprietary system to manufacture tapers to close tolerance specifications. Tapers ranging in size from .63/.60 (16/15mm) to .060/.010 (1.5/.25mm) can be consistently manufactured.
Depending on the final application, FTI will slump or mechanically bend tapered rod into simple and compound shapes, with bent angles up to 60°. Bends close to the end of a taper may require special handling to maintain the finish tolerance.
All rod and tapers are ground and polished to finished size. Edges are broken and beveled for safety unless otherwise specified.
