BBG and Hennecke, the two polyurethane (PUR) specialists, have presented Glassline, the world’s first casting machine that has specifically been designed for encapsulating vehicle windows. The machine is manufactured at St. Augustin, Hennecke’s headquarters. Since the beginning of 2015 when they started to cooperate within the project, BBG has already sold four complete systems to automotive glass processing companies in Hungary, the Czech Republic, China and the USA.

Glassline allows for encapsulating 80% of all automotive glass grades

Glassline 650/270, the standard version of the two-component machine, is designed for a maximum output of 650 cm3/s polyol and 270 cm3/s isocyanate. This allows for encapsulating around 80 percent of all glass panes in passenger and commercial vehicles. The offering also includes special Glassline versions with different blending ratios and output levels for glass used in convertible soft-tops.

Mixing head with flow-optimized nozzle geometry

Glassline is equipped with a type MT 12-2 mixing head from Hennecke, featuring a nozzle that has been designed to optimize flow characteristics. This results in an optimized mixing result. At the same time, the components polyol and isocyanate can be fed at lower pressure so that energy consumption is reduced by 30 percent in comparison to conventional models. An adapter can be used to mount the mixing head without any problems on any of the molds available in the market.

Due to its modular design, the Glassline machine requires a particularly small footprint. It can be easily expanded to allow for the installation of up to eight molding stations. All process parameters are recorded and documented by default so as to facilitate end-to-end quality control.

One-stop shop for end-to-end glass encapsulation systems

BBG GmbH & Co. KG is a manufacturer of molds, machinery and plants for the plastics-processing industry, focusing on polyurethane. The family-owned business is located in Mindelheim/Allgäu and run by Hans Brandner, the managing partner. With a headcount of 80, BBG expects to generate sales of 13 million euros in 2015. Thanks to Glassline, the company is now able for the first time to offer end-to-end solutions for encapsulating automotive glass from a single source.

Hans Brandner, the managing partner of BBG, says “Glassline is a technological high-end product, the only one of its kind in the world. It combines Hennecke’s comprehensive experience in terms of reaction molding machinery and our long years of expertise regarding the encapsulation of automotive glass. In this way we define a new standard for glass encapsulation.
