Glas Herzog’s smooth startup of Glaston SPEED BOX IG line
“We have a great deal of confidence in our supplier,” says Andreas Herzog, Sr., Managing Director of Glas Herzog. “Our cooperation with former Bystronic glass – and now Glaston – is just as you would want it to be as a customer. In fact, we’re one of their oldest customers – 44 years and counting.”
Glas Herzog was founded by the first Andreas Herzog in 1948 as a glass grinding factory in Waghäusel, Germany, near Heidelberg. Over the course of nearly 75 years – and three family generations – the company has evolved from a purely craftsman’s business to being flat glass experts. Today, it offers a full range of functional and insulating glass to window manufacturers in Germany and neighboring countries.
In 1978, Glas Herzog purchased its first Lenhardt insulating glass line. This makes the company one of Glaston’s oldest customers. For special glass production, Glas Herzog still operates a 1987 Lenhardt washing machine and 1991 Lenhardt inspection station.
The founder’s son, Andreas Herzog, Sr., along with his sons Andreas Herzog, Jr., and Thomas Herzog, say the key to developing and managing their business successfully over the years has been to retain “the human touch” as a top priority in all they do.
In December 2020, the Glaston SPEED BOX IG line was delivered to replace an old Lenhardt insulating glass line that had been operating for 26 years. Starting production in January 2021, this new line is running smoothly alongside two other Bystronic glass insulating lines that run fully automatically. Together, they enable Glas Herzog to produce more than 1,000 insulating glass units daily. The new line provides the company with high output, easy operation and robust construction for high machine component reliability. This individually configurable production line for insulating glass units with conventional spacers delivers high flexibility, excellent productivity and a long service life
“Without any manual intervention, prefabricated spacer frames are automatically filled with desiccant, precisely coated with butyl and then automatically positioned onto the glass. The shortest possible cycle times are achieved by parallel filling and transport processes. We can produce different frame dimensions, profile widths and glass thicknesses in any sequence. Insulating glass unit thicknesses of 80 mm are now possible.”

“We purchased the Glaston iControL and scanner upgrade to solve any concern with software or spare parts availability before they became an issue. Once installed, the upgrade helped us win a large glass façade project in Indonesia that required extremely high quality. Both we and Glaston can be proud of the high level of quality achieved,” says Matea Franjić, Chief Operating Officer (COO) of Kristal in Vitez, Bosnia and Herzegovina.Read more
