Since the beginning of the 1990s, LiSEC has been actively shaping the cutting possibilities of laminated glass. Several successful innovations have already been introduced to the market based on years of experience. At glasstec 2018 the latest generation of LiSEC laminated glass cutting machines was presented: the VSL-A.
Focus on the customer
In the last 20 years, LiSEC has supplied hundreds of laminated glass cutting bridges all over the world and further developed the underlying technology together with customers. In 2016, the starting signal was given to combine all the knowledge gained in a new revolutionary system to meet the needs of customers:
- Increasing proportion of laminated glass in the construction glass industry
- Cost pressure for processors
- Easy to use
- Increased degree of automation
- Maximum quality of the processed product.
A clear advantage with the triple A of the VSL-A
Time is money and every second the laminated glass cutting machine is not cutting is not only wasted but a loss. LiSEC set itself the task of precisely analysing the cutting process and identified the bottle neck: the heating process, which is necessary for heating the PVB layer in the laminated glass, was largely responsible for the cycle time of the system.
SIR (Selective Infrared Technology) – the revolutionary new heating technology developed by LiSEC has immense advantages in terms of reduced heating times. Where 25 seconds was previously required to heat the PVB layer, today it takes only 4 seconds. A saving of 21 seconds, which makes the VSL-A more efficient and productive than its comparable models.
At the same time, the heater now consists of identical 900 mm heating modules. In contrast to a continuous heating rod, these can be individually controlled. This reduces the cost of spare parts while at the same time reducing energy consumption.
All in all, the VSL-A enables between 15% and 30% increase in performance compared to conventional products on the market!
Higher automation and easier handling
"Lack of skilled workers" or "war for talent" are no longer foreign words in the glass industry. Finding good and qualified employees is no longer as easy as it used to be. This is the reason behind the demand for machines and systems with simple operation. For the LiSEC development team, the user-friendliness of the system and a largely autonomous cutting process were two absolute must-haves when planning the machine. The interaction between the system and the operator is largely limited to the unloading of the finished cut sheet.
- automatically disposes of off-cuts into a container
- turns sheets fully automatically up to the maximum size
- aligns the sheets automatically
- cuts the sheets with high performance
and this without complicated and time-consuming sheet handling.
Easy handling - system operators only unload the finished sheet!
Less wastage & better optimisation result = dramatically lower costs
Laminated glass is a composite of two glass sheets, one of which usually has a thermal or solar protective coating. Laminated with one or more layers of PVB foil, laminated glass is a complex product with a significantly higher price than float glass, for which the price increases exponentially with increasing glass thickness.
When cutting flat glass, sheets that are to be cut to size are optimised in a raw size glass sheet (usually jumbo glass in the format 6000x3300 mm). Here the reduction of wastage is the main focus. In simple words: dispose of as little laminated glass as possible as residue and fit as much laminated glass as possible into a raw glass sheet by means of good sheets.
To make this possible, LiSEC has developed the VSL-A, a system that ensures the highest cost efficiency on the market. The VSL-A can fully automatically cut off-cuts with a minimum of 20 mm for standard glass thicknesses. Any necessary edge cuts can be cut automatically with a minimum of 20 mm.
This low wastage increases the optimisation efficiency, because more sheets can be optimised into one raw glass sheet. This massively reduces the waste costs. It is almost unbelievable, but demonstrably confirmed, that six-figure Euro amounts of potential savings in terms of wastage per year are possible in comparison to conventional systems on the market.
Minimum 20 mm off-cuts & edge trimming up to glass thickness 66.10 (2x6 mm + 10 pcs. interlayer)
= Dramatically less wastage & better optimisation results
Realise savings with every raw glass sheet – the VSL-A is a worthwhile investment!
Glas Gasperlmair from Wagrain in Austria ordered a VSL-A37/33 at the beginning of 2019 and was so satisfied with the efficiency in the first year that by the end of 2019 they had already ordered a second system, in VSL-A47/33 size. Mr. Gasperlmair has recognised the potential of investing in a highly cost effective system whose ROI will quickly pay off for the company.
Numerous other customers from Germany, Austria, Poland, Romania and Greece are now convinced by the VSL-A technology!
