Compressed air requirements for bottle making plants

In the bottle production process, compressed air serves as the core power source and process guarantee, running through key links such as raw material processing, forming control, and product testing. With its oil-free characteristics and stable air supply capabilities, Granklin water-lubricated single-screw air compressor can accurately match the needs of the following scenarios:

1. Raw material conveying and mixing systems
The conveying pipes of plastic particles or glass raw materials rely on compressed air to form an air flow to promote the uniform flow of materials. Clean air sources can avoid impurities from being mixed and ensure the accuracy of raw material ratio.

2. Bottle body forming control unit
Blow molding machines, injection molding machines and other equipment shape molten raw materials into bottles through high-pressure air flow. The stability of air pressure directly affects the uniformity of bottle wall thickness. Water lubrication technology eliminates the risk of lubricating oil contamination and ensures that no foreign matter interferes in the forming process.

3. Cooling and drying processes
After demoulding, the bottle needs to be cooled by compressed air and residual moisture on the surface is removed. Continuous and stable air flow output improves production efficiency and avoids product deformation caused by fluctuations in air pressure.

4. Quality inspection and packaging
The airtightness testing equipment uses compressed air to fill the bottle body and determines the sealing performance through pressure changes. An oil-free air source prevents the introduction of pollution during the testing process and ensures the accuracy of quality inspection results; the pneumatic components of packaging machinery rely on stable air pressure to complete labeling, sealing and other actions.

Granklin air compressor uses water as the lubricating medium, combined with the compact structural design of a single screw and star wheel. While providing a continuously stable air source, it eliminates potential pollution to the oil circuit system from the root cause, and is highly in line with the bottling industry’s dual needs for air cleanliness and gas supply reliability.
