Insulating glass production line TPA

automaticcontinuous

The LiSEC TPA is a fully automatic system for applying thermoplastic spacer bars. It allows the highest flexibility by seamlessly switching between different dimensions of the glass. The stepless width adjustment allows switching between different spacer widths without the requirement for a waiting time. How is the TPA configured? The TPA consists of a drum melting pump (DMS-200), two intermediate tanks, a controlled hydraulic system and a flow control valve. How does the automatic processing of thermoplastic spacers work? The drum melting pump (DMS-200) heats the material and conveys it from the 200l drum into two intermediate tanks. These each have a volume of 20l and ensure uninterrupted operation of the TPA due to the alternating mode of operation. The material is metered by means of a controlled hydraulic system and a flow control valve. The volumetric measuring system directly in front of the application nozzle applies exactly the right amount of material and compensates for fluctuations in the material batch and temperature. New and improved metering technology ensures highly precise and reliable application. Furthermore, the process steps of assembly and pressing have been adapted to the special requirements of the thermoplastic material. The use of a special calibration station prevents overpressure in the unit and therefore supports the adhesion of the TPA material.
