Glass Bottle Manufacturing

Glass Bottle Production Process:

Glass bottle production process: raw material ingredients – added to the furnace for melting – feeding machine segmentation – mold forming – annealing and cooling – quality inspection – packaging and boxing – warehousing sampling – outgoing warehouse.

Construction of Glass Bottle Kiln:

1. According to volume or discharge amount, it is divided into:

Large kiln (daily production of 150-200 tons of molten glass)

Medium-sized kiln (daily output of 50-150 tons of molten glass)

Small kiln (daily production of less than 50 tons of molten glass)

2. According to product material color, it is divided into:

Green and white material glass bottle and jar kiln, plain white material glass bottle and jar kiln.

Glassware kiln, cosmetics kiln, color kiln (blue, brown, etc.)

White wine bottle kiln, red wine bottle kiln, borosilicate kiln, etc.

Glass bottles with different material colours

3. According to the heat source, it is divided into:

Flame kiln (fuel is heavy oil, coal, gas, natural gas, etc.)

Electric kiln (electric energy)

Flame/electric furnace (mainly fuel and supplemented by electric energy)

Glass bottle production machine:

Line machine: mainly produces glass bottles and jars.

Electronic machines: mainly produce special-shaped products and thick-soled products.

Press and blow molding machine: mainly produces dishes and other daily utensils.

Manual machine: mainly semi-manual and semi-machine bottle production, suitable for small order production.

Glass bottle fuel and ingredients:

Fuel: electricity, heavy oil, gas, coal, etc.

Ingredients: soda ash, quartz sand, broken glass, sodium carbonate, limestone, etc.

Glass bottle mold and adjustment:

Mold making: First select the bottle making equipment according to the shape, weight, and ingredients of the product, and then combine the functions of the equipment to design a mold that matches it; the molds are divided into small mouth molds, wide mouth molds, and vessel molds. The order quantity and communication with the production factory determine the quantity of molds that need to be made. Generally, the proofing molds are made first, and then bulk molds are produced after the proofing is confirmed. Molds for special-shaped products require multiple proofing. To determine their reasonable technical parameters, if there are any differences from the first time, then the samples produced are slightly different, and the mold needs to be repaired and adjusted and then sampled again to confirm the best technical parameters.

Production adjustment: production technicians need to communicate frequently with mold designers, and make optimal adjustments during the production process based on data from different results such as furnace temperature, machine speed, wind power, machine air pressure, glass type, etc. Only the products produced can reach perfection.

Glass bottle forming and annealing:

After the glass liquid flows into the mold through the pipe, the air is blown into the mold through the air pipe so that the glass liquid is evenly filled around the mold, reaching a hollow state in the middle and quickly cooling and shaping; the robot grabs the molded product from the mold and places it. The cooling continues on the conveyor belt; the product enters the annealing kiln through the conveyor belt for multiple segmented cooling at different temperatures at different stages and is finally formed.

Glass bottle inspection and packaging:

Molding inspection: After the product comes out of the mold, technicians will observe the product quality online and make adjustments at any time.

Light inspection: After the product comes out of the annealing furnace, the defective and defective products are directly discarded through the light inspection equipment manually.

Sampling inspection: Follow-up quality inspectors conduct sampling inspections of products in production at any time, and promptly respond to production line technicians for quality problems that arise and make timely adjustments.

Packaging inspection: Before the finished product is put into the box, the quality is manually inspected again to see if it meets the standard. If it fails, it will be discarded.

Warehousing sampling inspection: After the products are put into the warehouse, the quality inspector will randomly inspect the bulk goods and make a quality inspection report.

Packaging form: pallet, carton, carton + pallet, tray + pallet, etc.

Deep processing of glass bottle decoration:

After the glass bottles leave the workshop, they enter the deep processing workshop for secondary processing. Various deep processing techniques such as printing, color spraying, frosting, cutting, or other decorations may cause a small amount of loss during the decoration process. This can be determined in the glass bottle production plan. Make additional reserves in advance.
