The general description above is equally applicable to contoured heat sealing bands in 2D or 3D:

• The contour of the heat sealing band must be matched to the required seam and to the contour and geometry of the substructure.
• Bar end blocks and wedge-shaped edges are also required here.
• The ends of the heat sealing band should have a low-impedance coating of copper, silver or nickel.
• The electrical connections should be adequately sized to prevent measuring errors due to temperature rises when determining the resistance.

All contoured heat sealing bands supplied by ROPEX are designed using a 3D CAD tool. The files created in this way are used for further processing, e.g. laser cutting or anti-stick covers. The technical specifications are carefully documented and kept together with a reference sample, which can be used again for follow-up deliveries.
