Today's products require more high quality and precise sealing. IPTE's laser expertise is available for competitive automated laser plastic welding. The optimal and closed loop welding process utilizes high speed scanning for quasi-simultaneous welding. There is a low cost clamping mechanism to ensure a quick change-over. The system is controlled using IPTE's user friendly interface TS1 and includes collapse measurement, laser power and force control during the welding process. The welding process is digitally controlled and monitored. The clamping lid supports inner and outer surface and a cooling system improves process control and cycle time.
