Amber Glass Tube, Glass Processing Plant, Pharmacal Tube Making

1. Brief introduction

Glass is a special amorphous inorganic nonmetallic material. The main component is silicate, a non-crystalline solid with an irregular structure.

Glass melting is the most important process in glass production, it is a forming process where the batched materials form a qualified liquid evenly with no bubbles under high temperature heating.

At present, most of the tube glass production line mainly adopts horizontal stretching Danner process and Vello process.

The melting process is divided into five stages as following, each section has its inner connection, affecting each other. If one stage has imperfect performance, it will influence the next stage, and ultimately affect the quality of glass.

2. Forming process

• Danner process

The glass liquid flows out from the furnace through the throat, goes into the rotating cylinder, the glass liquid will form a tubular type under a rotating speed of the cylinder. The tubular shape will be stretched and form a glass tube via graphite guide roller by Danner machine.

• Vello process

The glass liquid flows out from the throat, and goes into a heat-resistance alloy pipe, the glass liquid will form into a tube under the function of compressed air.

3. Application of tube glass

The optimal choice used for pharmaceutical glass tube must be neutral borosilicate glass tubes.

General paramter of borosilicate glass tube:

Main material componsition:

• SiO2
• B2O3
• Al2O3
• Na2O
• K2O
