MACHINES FOR GLASS PRODUCTS DRAWING FROM A GLASS BLOCK

Our company fabricates machines designated for drawing of glass tubes and rods of any cross section (circle, ellipse, polygon) from a melted glass block. The tube diameter and wall thickness are determined by the drawing die dimensions.

Glass products high accuracy is provided by the use of cylindrical chambers with independent heating elements (heating zones), designated for creation of the desired temperature distribution along the whole length and angular coordinates of the cylinder and high accuracy electric motors providing for the specified drawing rate.
Automatic adjustment is performed on the basis of results of measurements made by a two axis laser gage.

The machine may be equipped with a small size glass furnace.

We can fabricate airtight heating chambers in order to perform in vacuum or under pressure conditions.

A constituent part of our equipment is automatic control systems including electronic control systems and personal computers.

The machine technical specifications:

  • a glass block dimensions are:
    • 120x150x400 mm;
    • 150x150x400 mm;
    • 120x120x400 mm;
  • temperature in the furnace is 400-1000°C±1°C;
