Clear Customized Size Tableware Glass Production Line Wine Goblet for Domestic Glass

Wine Glass Goblet Production Line

1.Brief introduction

Glass tableware is a type of tableware made from glass. It typically includes plates, glasses, mugs, and other items used for eating and drinking. Glass tableware is made from a variety of materials, including soda-lime glass, lead crystal, and borosilicate glass. Glass tableware is typically transparent, allowing for a clear view of the food and drink being served. It is also heat-resistant, making it suitable for hot and cold dishes. Glass tableware is also easy to clean and can be reused, making it an environmentally friendly option.

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.

2. Advantage

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

3. Materials

Stable chemical components in the raw materials are very important,  which will affect the effect.

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

Physicochemical changes in each glass melting stage:

1. Silicate forming

In this stage, the components of batched materials will produce a physicochemical solid phase reaction during heating process, in which the gaseous products will be released from the batched materials and produce a new opacity sinter ultimately, which is formed by silicate and SiO2.

2. Glass liquid forming

In this stage, the sinter will be melting and the silicate and SiO2 in sinter will change to flint glass liquid with a plenty of bubbles. However, its chemical components and character are not even.

3. Clearing

The glass liquid is continuously heated, and its viscosity is reduced with plenty of gaseous sundries released, which should eliminate the visible bubbles with the pool of liquid.

4. Homogenization

The glass liquid is kept at high temperature for a long time, the ripple eliminates by diffused function and homogenizes as a whole. The temperature of homogenization can be lower than the clearing stage.

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 I.S. machine or 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. Pushing speed is adjusted by inverter, quantity of pushing numbers is controlled by digital counters.

• 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.

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.

The defect of glass production is mainly due to the melting process, the melting quality has a close relationship with the quality of yield production, production cost, fuel combustion, furnace campaign, etc. It is important to ensure the physicochemical reaction of batched materials perform well during the whole melting process, and make sure the whole process is smoothly operated and for manufacturing high quality glass products.
