Press Duration Control
Closed-Loop Wall Thickness Control - Constant press duration
Our solution controls the individual phases of the pressing process. The patented procedure records how long the plunger stays in the glass and then regulates the pressure and time accordingly. Control of the press duration, i.e. the time the plunger remains in the glass, ensures repeatable wall thicknesses. This is a critical quality feature in hollow glass production.
Optimal Usability
The automatic press duration control is an optional component of the Heye Process Control.
- A job database enables fast and convenient job changes
- All pressure and time values can be preset on the monitor
- A bar graph of the pressure stages shows potential differences between individual cavities
- Limit value excesses are displayed in plain text
- A pressure sensor in the proportional valve shows the pressure course as a line diagram over time
Extensive diagnostic tools are included in the package.

FAQs Press Duration Control
What is the main function of the Press Duration Control?
Press Duration Control ensures a constant plunger dwell time in the glass and automatically regulates pressure and timing across all pressing phases. This ensures repeatable wall thicknesses and even distribution of the glass.
What benefits does the Press Duration Control offer?
It ensures consistent wall thickness, improves overall product quality, enhances process safety and reduces defects. Differences between cavities are directly visualized.
How is the Press Duration Control integrated into existing systems?
It is an optional component of the Heye Process Control and can be retrofitted into many existing IS machines. A job database enables quick job changes, and all pressure and time parameters can be preset via the operator interface.
