Why Vacuum is Transforming Glass Manufacturing
Traditionally, glass molding uses compressed air to shape molten glass into containers. However, by integrating vacuum into the Individual Section (IS) machine process, manufacturers benefit from:
- Up to 5x less air and energy consumption
- Faster production cycles
- Improved product consistency and shape
- Lower operational and maintenance costs
Vacuum allows the glass glob to be formed more efficiently and with better precision, especially at high production speeds. It also helps in achieving cleaner molds, less scrap, and reduced downtime.
GHS VSD⁺ Rotary Screw Vacuum Pump – Best-in-Class for Container Glass Production
Atlas Copco’s GHS VSD⁺ rotary screw vacuum pumps are engineered specifically for energy-intensive applications like glass molding. Designed with Variable Speed Drive⁺ (VSD⁺) technology, these pumps adjust output to match demand—eliminating wasteful energy usage.
Key Benefits of GHS VSD⁺ for IS Machines:
- Energy savings up to 50% compared to fixed-speed vacuum pumps
- Flow range from 350 to 5,400 m³/h – ideal for standalone or centralized systems
- Low noise operation and best-in-class oil retention
- Easy plug-and-play installation and minimal maintenance
- Graphical control interface with remote monitoring (SmartLink-ready)
- High reliability and long service life
- Seamless integration into existing compressed air infrastructure
With real-time performance tracking via the Vbox energy audit tool, you can measure exact savings and efficiency improvements tailored to your operation.
Vane vs. Oil-Injected Screw Vacuum Pumps: What’s Best for IS Machines?
While rotary vane pumps have long been used in container glass molding, they struggle with pressure fluctuations and variable demand. These fixed-speed pumps run at full capacity even when it’s not needed, leading to energy waste and wear.
In contrast, the oil-sealed screw vacuum pumps like Atlas Copco’s GHS VSD⁺ offer:
- A wider operating range
- Precise vacuum level control under fluctuating load
- Lower energy consumption
- Enhanced stability and reliability
This makes screw technology the superior choice for high-volume, high-speed IS machine operations.
Centralized Vacuum Systems for Glass Plants
For large-scale production facilities, a centralized vacuum system brings even more benefits:
- Automated control of multiple pumps to match real-time demand
- Energy optimization across the entire vacuum network
- Improved pressure stability during mold changes and production breaks
- Simplified maintenance planning and cost-effective operation
- Redundancy and scalability for future expansion
Whether you’re producing bottles, jars, or specialty containers, a centralized vacuum system ensures maximum efficiency and product quality—with reduced operating costs.
