50ml-500ml, Flint Jar, Glass Bottle Production Line, Container Glass for Jam
1. Brief introduction
With a good chemical stability and excellent artistry, the glass container has become one of the most popular packing materials. It is also extensively applied in food and beverage industries, which has occupied an important position in the market that cannot be ignored.
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. Types of container glass classification

| 4 | Rectangle |
| 5 | Flat |
- Sort by diameter of bottle neck:
| Item | Description |
| 1 | Wide-mounth bottle or jar |
| 2 | The inner diameter of the bottle is over 30mm, with small or no shoulder, which is usually used for semifluid and powder or bulk solid goods. |

| Item | Description |
| Flint / Clear | Most of the glass containers are flint, which will keep stores more visually. |
| Green | Usually, the green bottle is used for drinks and beers. |
| Brown / Amber | Normally, the brown bottle is for pharmaceuticals or beers, this kind of color can absorb ultraviolet rays, which will help to protect the stores. |
| Opal | This kind of bottle is for cosmetics, vanishing cream, unguent and liquor. |
3. Physicochemical changes in each glass melting stage:
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.
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.
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.
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.
4. Main equipment of glass forming
Shear angle:adjustable between RH30°- LH 90°
Available for S.G, D.G and T.G.
I.S. machine is a standard production equipment of glass making, it has various of gobs and sections, which could suitable for all kinds of combustion types and different specifications of annealing lehr.
The higher precision machining and assembly process ensure the stability and reliability of I.S. machine.
Use continue cam in different section.
Pneumatic mold clamping, usually use 5 bar compressor air for stronger clamping the mold.
Scoop control by air cylinder, reject glass.
Electric valve and regulator use SMC.
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 is installed in front of annealing lehr for cross conveying the glass product and works with stacker to push them into annealing lehr.
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 can be continuous annealing of tableware, bottles, cans, and other glass products.
| Item | Description |
| Heating type | Electricity |
| Control mode | Continuous proportionate automatic control |
| Temperature control precision | ±1℃ |
| Max temperature | 630 ℃ |
| Drive | Belt running by stepless speed regulation, frequency control by inverter |
Different kinds of packing devices could meet different packing types of different kinds of domestic glass products.
