Vitro Architectural Glass (formerly PPG Glass) and GED Integrated Solutions, LLC (GED) have announced the launch of Intercept LiteLock鈩, a new extruder tip and sealant bead application system that provides licensees of 滨苍迟别谤肠别辫迟庐 insulating glass technology with enhanced efficiency, performance and quality improvements.
Intercept LiteLock鈩 facilitates 30% to 50% faster processing speeds on GED鈥檚 滨苍迟别谤肠别辫迟庐 Oven & Roll Press while creating a wider manufacturing process window. This results in a more consistent, uniform and secure seal between the 滨苍迟别谤肠别辫迟庐 spacer and the glass lite, which maximizes the service life of 滨苍迟别谤肠别辫迟庐 insulating glass units (IGUs) and enhances window makers鈥 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 GED nozzle tip, which applies a rounded sealant bead during the extrusion process onto the 滨苍迟别谤肠别辫迟庐 spacer, the patent-pending Intercept LiteLock鈩 nozzle tip applies sealant in a unique bead geometry, resulting in robust adhesion to the spacer metal substrate at near-finished bond line width.
鈥淐hief among the many benefits of Intercept LiteLock鈩 is the high-speed processing power unlocked by this new sealant bead application technology,鈥 said William Davis, Senior Technical Services Engineer at Vitro Architectural Glass. 鈥淭he Intercept LiteLock鈩 nozzle tip design reduces the amount of required squeeze-out during the roll-pressing process, so 滨苍迟别谤肠别辫迟庐 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.鈥
In addition to standard double glazed IGUs, the Intercept LiteLock鈩 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 SmartExtruder鈩 i-3 sealant and desiccant application systems to the new Intercept LiteLock鈩 system with a minimally invasive process.
The 滨苍迟别谤肠别辫迟庐 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.
