Glaston has delivered its 1,500th UNIT’ASSEMBLER machine to AGC Glass Europe in the Czech Republic, marking a milestone for the company’s insulating glass production technology.
The machine, a ZPG-V model, will be used by AGC Glass Europe to produce insulating glass units for Pyrobel-T, its fire-resistant glass product. Glaston said the line will support a wide range of formats, from standard rectangular units to almost all other shaped formats.
The UNIT’ASSEMBLER is designed for the automated assembly, gas filling and pressing of insulating glass units, known as IGUs. According to Glaston, the technology can be used for double, triple and quadruple IG units, making it suitable for manufacturers seeking high levels of automation and flexibility.
Jens Mayr, executive vice-president of Solutions and Operations at Glaston, said the delivery reflected customer confidence in the machine’s performance.
“The delivery of the 1,500th UNIT’ASSEMBLER is a strong sign of our customers’ confidence in the quality and performance of this machine,” he said. “Especially in a highly competitive market such as insulating glass production, process reliability, productivity and consistently high quality are decisive factors.”
Glaston said the machine’s alignment system uses a lifting beam at the lower running level and a fixed stop at the front edge to position glass panels precisely. This is intended to ensure uniform compression across units, regardless of whether they are double, triple or quadruple glazed.
The UNIT’ASSEMBLER also includes integrated gas filling technology. A calibrated gas sensor continuously monitors the filling process, which Glaston said helps ensure consistent and reproducible gas quality.
An optional synchro gas-filling function enables triple IG units to be filled with gas in the same amount of time as double IG units, according to the company.
Glaston said the system’s modular design allows it to process standard rigid and flexible spacers, including TPS®. Depending on the version, the machine can also produce extra-long insulating glass units in a two-stage process.
The company said the UNIT’ASSEMBLER can handle working heights of up to 3.30 metres and workable lengths of up to 5.00 metres. In the tandem version, workable lengths can extend to up to 6.00 metres.
The delivery to AGC Glass Europe underlines what Glaston described as the machine’s strong position in Europe and worldwide. Since its introduction, the company said the UNIT’ASSEMBLER has become a central component in modern insulating glass lines, helping improve productivity and quality in glass processing.
Glaston said the milestone reinforces its position as a provider of technology for the insulating glass industry.
Why This Matters: Glaston’s 1,500th UNIT’ASSEMBLER delivery underlines how automation, flexible IGU production and reliable gas filling are becoming baseline requirements for competitive glazing. For fabricators, the milestone signals continued investment in productivity, quality control and complex fire-resistant glass formats across global markets.
