Glass tube is basic structural components of optical communication devices. It has small size, high precision, high hardness, and excellent environmental resistance. Thin glass tubes are used in optical devices such as optical collimators, isolators, high-power lasers, etc. The main manufacturing method is prefabrication of glass rods. After cleaning, they are clamped above the high-temperature graphite furnace and sent into the heart of the high-temperature graphite furnace protected by inert gas. A series of program operations such as continuous pulling, drawing, and cutting are performed, directly and quickly in large quantities. Producing large-diameter glass tubes with transparent surfaces and high dimensional accuracy is suitable for mass production, which can significantly reduce component costs and improve component quality.
Features of Thin Wall Glass Tubing
Borosilicate Glass, silica (SiO2) content 80%, softening point >800°C, high strength, high hardness, high light transmittance.

The glass rod tube is made of warm melted wire drawing. The surface is transparent, which eliminates local hidden micro-cracks on the surface. It is not easy to crack and break when dispensing and fixing, and the dispensing qualification rate is high.
