1. Brief introduction

Opal glass is a kind of glass material formed by opactifying effection produced from tiny particle in fluoride via light scatting effect.

At present, the opal glass is a regularly used glass product in daily life.

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.

Glass melting is a very complex process, it includes physical, chemical and physicochemical phenomena and reaction. These phenomena and reaction lead the mechanical mixed raw materials to complex melting glass liquid.

• Characteristic of raw materials
• Chemical component of batched materials
• Material feeding method
• Melting temperature

2. Advantage

• Increase the strength and thermal impacting property of the glass product.
• Increase the decoration apperance of the glass product.

3. Materials of opal glass

Stable chemical components in the raw materials are very important, especially the content of fluor and sodium fluosilicated, which will affect the opacifying effect.

To produce high quality product of opal glass, a high quality of silica sand shall be reqruied. The main materials to produce opal glass are below,

Designed components

4. Main equipment of forming device

• Gob Feeder / Serve Gob Feeder

Shear angle:adjustable between RH30°- LH 90°
Available for S.G, D.G and T.G.

• Press machine

Use continue cam in different section.
Pneumatic mold clamping, usually use 5 bar compressor air for stronger clamping the mold.

• Transfer ware

Transfer ware is designed for conveying the glass product from press machine to cross conveyor in front of the annealing lehr quickly and stably, which is especially applicable to high-speed glass production line.

• Cross Conveyor

Cross conveyor is installed in front of annealing lehr for cross conveying the glass product and works with stacker to push them into annealing lehr.

• Stacker

Stacker is used for pushing the glass product from the cross conveyor into annealing lehr.

• Annealing lehr

Annealing lehr can be continuous annealing of tableware, bottles, cans, and other glass products.

• Packing devices

Different kinds of packing devices could meet different packing types of different kinds of domestic glass products.
