Robotic flange cleaning and formed‐in‐place gasket application systems

Describes the rationale, purpose, and design of the Loctite Corporation One‐Pass TM (patent pending) robotic flange cleaning system. Also details two complementary Loctite TM formed‐in‐place (FIP) gasket sealant dispensing systems: AccuPump 1000 (a progressive cavity positive displacement pump for silicone and anaerobic FIP technology), and PressPak TM 1000 (patent pending) (a pumpless dispensing system for silicones, anaerobics, and high viscosity abrasive‐filled adhesives or solder pastes). Integrated with a high‐performance Loctite dispensing system, the One‐Pass TM creates a highly robust, robotically controlled FIP flange‐sealing assembly process. This technology combination enables worldwide producers of engines, transmissions and axles to replace expensive molded gaskets with higher‐performing FIP adhesives and sealants at a fraction of the cost.
