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
| Item | Description |
| 1 | Roundness (majority) |
| 2 | Oval |
| 3 | Square |
| 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.
