In industrial practice, vacuum usually describes an enclosed space in which the pressure is below atmospheric pressure. There are numerous vacuum applications, including:
- Packaging processes
- Pneumatic conveying
- Pressing and laminating
- Workpiece handling
What these vacuum applications have in common is that a vacuum is generated inside a technical system. However, the exact purpose of the pressure ratios differs. For example, the vacuum is used to suck in objects during workpiece handling.
When packaging under vacuum, the focus is on protecting the goods from oxygen, moisture and dust.
#1 Definition of vacuum applications
Vacuum applications are technical processes for manufacturing, conveying and packaging for which a pressure below atmospheric pressure is generated.
#2 Importance of vacuum applications
Vacuum applications play a special role in sealing technology. In order to prevent the inflow of air from the environment, the components of the sealing system must be of a particularly high quality. This applies to the sealing surfaces as well as the sealing element itself. When selecting materials, the focus is on processing quality and gas permeability.
