Processes
Most of the equipment
used in producing Garner parts is proprietary. It was developed over years
of use. Our primary process is the redraw. This process starts with glass
tubing which is heated until it softens sufficiently to be pulled or "redrawn."
Careful control of the source tube in-feed and redraw rate 
enables
tight outside diameter (O.D.) tolerances to be held. The O.D. and I.D.
variations are held to tolerances normally associated with machined metal
parts.
The "scribe & break" to length process is utilized when required, but most Garner Glass parts are sawn to length. The speed and accuracy of the diamond saw blade gives the highest accuracy with least labor. This is but one reason Garner parts have earned the reputation of having the highest quality to final cost ratio. Other specialized equipment may be utilized to glaze part ends, grind tight O.D. dimensions, flow one end closed to act as an optical lens or become a preform blank to be used by our customer in their product or process. We feel it important that our customers know that Garner Glass Company has NO interest in developing any product beyond those made from glass tubing, sheet or cane (rod). We make beads for hermetic seals - but make no feed-thrus or headers; we make fuse and reed switch housings but no fuses or switches, flow restrictors but no medical equipment, PC board spacers but no computer products, fiber optic splices but no communication products... ad infinitum. In short, no matter what your end product we will NOT end up being your competition. Your product is safe with Garner Glass Company.
