Condition: excellent (used), Bystronic Type: ERMM180 Thermoplastic Applicator Application Area The thermoplastic applicator applies a thermoplastic material to rectangular glass panes within a production line for solar modules. The material forms a seal with a second glass pane, which is applied in a later process step. The panes are fed in, processed, and removed on horizontally running belts/conveyors. The thermoplastic applicator is a highly sophisticated machine that must meet many requirements with great precision. For this reason, you should only process raw materials (glass, sealant) that meet the specifications on the following pages. This helps to achieve high-quality and safe production. Performance and Connection Values Maximum transport speed: 18 m/min Height of the glass running surface: 1100 mm Height of the applied sealant bead: 0.5 to 1.2 mm Maximum width of the applied sealant bead: 12.0 mm Required constant input pressure, pneumatics: 6.5 to 8.0 bar Operating pressure, pneumatics: 6.0 bar Compressed air consumption, normal operation: 10 normal liters/min Compressed air consumption during drum change: 500 normal liters/min Average energy consumption per hour: 10 kWh Working temperature of the sealant: 110°C to 130°C Environmental Conditions and Emissions Minimum ambient temperature: +15°C Maximum ambient temperature: +35°C Maximum relative humidity: 75% Sound level: less than 70 dB (A) Requirements for the drums for the sealant Design: Material container D18 according to DIN 6644 – with base (F1) and smooth outer surface (body design, smooth).

The material must be flowable in the range of approximately 110°C to 130°C and exhibit a defined viscosity profile. Use only materials that have proven themselves in practice and that have been approved by the manufacturers of these materials and by Bystronic for the intended use. Detailed product descriptions and information on the handling, storage and disposal of the material used can be found in the information sheets and safety data sheets, which the manufacturers of the materials will gladly provide.
