Laminated glass is being used in an ever wider range of applications, while at the same time, requirements for process reliability, flexibility, and cost efficiency continue to rise. LamiPress expands the LiSEC portfolio with an innovative, highly precise, and scalable solution for laminated safety glass production.

Manufacturers of laminated safety glass face the challenge of mapping increasing throughput volumes, varying glass formats, and the highest quality requirements within stable and efficient processes. At the same time, production space is limited, product mixes are variable, and process reliability is critical to avoid waste and achieve predictable cycle times. Many companies therefore require flexible, scalable solutions that match their available floor space, capacity targets, and quality requirements.

This is exactly where LamiPress comes into play—as a technology that combines production reliability, efficiency, and flexibility in a single system and fundamentally rethinks the classic lamination process.

 

LamiPress – PROCESS-STABLE TECHNOLOGY FOR LAMINATED GLASS PRODUCTION

The technology is based on a two-stage process consisting of cold vacuum de-airing and a temperature- and overpressure-controlled lamination process. This is supported by a transfer plate logistics system that enables parallel process steps. High reproducibility is achieved through the precisely controlled lamination process within the LamiPress.

 

1. PREPARATION & COLD VACUUM PRE-LAMINATION

After the glass packages are assembled in the cleanroom, they are positioned on a transfer plate. These are 20 mm thick solid aluminum carrier plates on which the glass packages remain throughout all process steps, ensuring clean and reproducible glass handling.

This is followed by the cold vacuum phase, which typically lasts around 30 minutes. During this step, air inclusions are removed and the glass package is prepared for the subsequent lamination process.

Because this step takes place outside the LamiPress machine, multiple transfer plates can be operated in parallel. While one transfer plate is being loaded in the cleanroom, another is in the cold vacuum station, one is inside the LamiPress, and another is in unloading or post-cooling. After completion of a lamination cycle, the transfer plates rotate one position forward. This principle enables a continuous production flow and significantly improves throughput times.

 

2. LAMINATION PROCESS IN THE LAMIPRESS

After the cold vacuum phase, the transfer plate is inserted into the LamiPress. The lamination process then takes place, controlled by temperature, vacuum, and overpressure.

Depending on the glass configuration, the average lamination time is approximately 60 minutes. For standard builds such as 2 × 4 mm glass, it is around 45 minutes. Cooling down to handling temperature takes place inside the LamiPress, while final cooling occurs outside the system.

 

3. UNLOADING & POST-COOLING

After lamination is complete, the transfer plate is removed. The glass cools down completely on the transfer plate before being unloaded and further processed. The direct exchange of transfer plates also allows the use of residual heat from the previous process.

By using multiple transfer plates, preparation, de-airing, lamination, and cooling run simultaneously, enabling a continuous production process.

 

THE 5 KEY STRENGTHS OF LAMIPRESS

1. Scrap rate below 1%

Stable and reproducible process control minimizes sources of error and ensures reliable results with every cycle.

2. Precisely scalable system design

LamiPress is tailored to throughput, product mix, and available floor space—delivering an exactly fitting solution instead of a standard size.

3. Maximum flexibility even with a variable product mix

On average, a new batch of finished laminates is available approximately every hour. This allows maximum flexibility with changing product mixes - without loss of productivity..

4. Stable and predictable cycle times

The clear structuring of process phases ensures a consistent and calculable production flow.

5. Flexible layout and system variants

From compact, manual systems to fully automated lines, LamiPress can be integrated into a wide range of production environments and expanded as required.

 

LAMIPRESS PRODUCT PORTFOLIO

The LamiPress product portfolio includes modular lamination systems based on a flexible transfer plate logistics concept, configurable for different production sizes, glass formats, and process requirements. 

 

The machines are available in multiple variants—from compact base systems to extended configurations. The four expansion levels range from the Basic version through Twin-Table and rotary configurations to the LamiStore solution. With each expansion stage, the number of integrated transfer plates increases, along with the possible throughput.

This allows the system to be precisely matched to the respective product mix, available production space, and desired capacity.
