New extruder tip and sealant bead application system for Intercept® technology improves efficiency and quality
PITTSBURGH, September 13, 2021 | Vitro Architectural Glass (formerly PPG Glass) and GED Integrated Solutions, LLC (GED) have announced the launch of Intercept LiteLock™, a new extruder tip and sealant bead application system that provides licensees of Intercept® insulating glass technology with enhanced efficiency, performance, and quality improvements.
Intercept LiteLock™ facilitates 30% to 50% faster processing speeds on GED’s Intercept Oven & Roll Press while creating a wider manufacturing process window. This results in a more consistent, uniform and secure seal between the Intercept spacer and the glass lite, which maximizes the service life of Intercept insulating glass units (IGUs) and enhances window makers’ operations by offering increased throughput, lower oven and roll press exit temperatures, reduced energy consumption, reduced consumable parts costs, precise sealant application and a smoother, more forgiving application process.
Compared to the standard nozzle tip, which applies a rounded sealant bead during the extrusion process onto the Intercept® spacer, the patent-pending Intercept LiteLock™ nozzle tip applies sealant in a unique bead geometry, resulting in robust adhesion to the spacer metal substrate at near-finished bond line width.
“Chief among the many benefits of Intercept LiteLock™ is the high-speed processing power unlocked by this new sealant bead application technology,” said William Davis, Senior Technical Services Engineer at Vitro Architectural Glass. “The Intercept LiteLock™ nozzle tip design reduces the amount of required squeeze-out during the roll-pressing process, so Intercept® can run faster and at lower post – heating process temperature, which results in a cooler IGU at the oven and roll press exit conveyor that is near ready for argon filling and fourth corner sealing.”
In addition to standard double glazed IGUs, the Intercept LiteLock™ system has been rigorously tested with triple glazed IGUs across multiple oven and roll press speeds and temperatures to establish effective processing recommendations that will ensure robust glass and spacer adhesion, including the traditionally difficult to bond center lite.
Residential window manufacturers can upgrade their existing GED Intercept® spacer systems to Intercept LiteLock™ with a minimally invasive process. The new system is compatible with all GED SmartExtruder™ i-3 sealant and desiccant application systems.
The Intercept spacer system, which is constructed in a U-channel design with tin-plated steel or stainless steel rather than traditional box shaped metal or foam, has been fabricated into more than 600 million windows in Europe and North America.
