Flat and bent tempered glass production

«Siberian Glass Company» produces flat and bent tempered glass. The company is supplied with two glass tempering lines — Tamglass (Finland) and North Glass (Chinese People's Republic). The production is organized on a twenty-four hour basis.

Tamglass horizontal tempering furnace with a cyclic loading is made for flat tempered glass production at the innovative forced convection technology. Tamglass furnace can temper low emissivity glass (Low-E type) with the emissivity coefficient Kə up to 0.04.

Technical capabilities of flat tempered glass production at Tamglass furnace:

• «soft» coated low emissivity glass tempering (Low-E)
• output of products with high optical and mechanical property in accordance with Russian GOSTs, European and worldwide standards
• tempered glass thickness: 3.8—19mm
• Maximum tempered glass sizes: 2 440×4 800mm

Flat and bent tempered glass production is executed at North Glass automatic glass tempering system SM-12B 3610 (Chinese People's Republic), that is the analogue of Tamglass horizontal glass bending and tempering line HTBS (Finland). A distinctive feature of the present equipment is the roller system that allows to curve glass without bending frame usage.

Technical capabilities of tempered glass production at North Glass equipment:

1. Flat glass tempering:

• Maximum glass sizes: 2 440×3 660mm
• Minimum glass sizes: 300×150mm
• Glass thickness: 4 — 19mm
  

2. Bending and bent glass tempering:

• Maximum glass sizes: 2 440×1 000mm
• Minimum glass sizes: 400×300mm
• Glass thickness: 4 — 12mm
• Minimum bent radius: 450mm
  

3. Types of glass to temper:

• Clear glass
• Thermal control glass (K-glass)
• Tinted glass
• Sandblasted glass
• Patterned glass etc.

General information

Tempered glass — the glass subjected to a special thermal processing, which makes it stronger and more resistant to temperature fluctuations.

Glass tempering is held by glass heating up to 650 — 700˚C and its further rapid cooling. Under these processes external glass layers are highly pressed while inside layers come into wide condition forming pressure system inside the glass. As a result glass becomes stronger in a mechanical and thermal sense. When reaching a mechanical strength limit, tempered glass shatters into tiny pieces without blunt edges. That is why apart from mechanical strength and resistance to a thermo shock effect, tempered glass refers to safety glass.

Glass tempering is the last production operation. Glass cutting, grinding, edging and image embossing should precede tempering, because tempered glass can not be treated mechanically.
