RESISTRON HEIZLEITER
Wir entwerfen und fertigen kundenspezifische Heizbänder und Werkzeuge für neue Projekte, die genau Ihren Anforderungen und Projektspezifikationen entsprechen.
Kundenspezifische Konturen von Heizbändern
Unsere Möglichkeiten sind vielfältig: Von der Konstruktion nach Ihrem Design, über die Anfertigung bestehender Bänder bis zur Optimierung des Designs für beste Schweißlösungen. Für neue Projekte entwerfen und fertigen wir kundenspezifische Konturen und Werkzeuge nach Ihren Vorgaben.
Verfügbare Konturen:
- Offene und geschlossene Konturen (von einfachen bis zu komplexen Formen)
- Groß- oder Miniatur- Präzisionsbänder
- Trenndrähte für cut & seal
- Präzise positionierte Befestigungslaschen und geschweißte Befestigungselemente
- Bei Bedarf: Oberflächen-und Identifikationskennzeichnung
- Anschlussoptionen: Innen-Außenlaschen (oder beides),
- Definierte Wärmezonen (Zebrabänder – Teilbereiche verkupfert)
- Kupfer oder kupfer-und nickelbeschichtete Heizbänder
Straight heat-sealing bands
Straight heat-sealing bands (strips) are the most widespread.
Their thickness, width, profile, length and alloy vary according to the application. Heat-sealing bands can have a thickness of 0.1 mm to 0.4 mm and are usually between 2 mm and 10 mm wide. The length ranges from a few centimeters to several meters.
The part of a flat band facing the film is generally wedge-shaped (tapered), to ensure that a sufficiently strong sealed seam is also created at the edges.
The design of the heat-sealing band ends also varies considerably. A reliable connection must be guaranteed between the band and the bar end block. Easy handling and freedom from contact resistances are also important. Sleeves, eyelets and brass end pieces are used for this purpose.
Parts of the heat-sealing bands that don’t need to be heated for sealing – especially the free ends – are passivated by suitable types of coating. This prevents them from overheating, which is also vital for precise temperature control.
Heat-sealing bands play a functional role in the impulse heat-sealing process, which means we – as the supplier – have no room to compromise on quality.
2D contours
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.
3D contours
Heat-sealing bands can also be supplied with a 3D contour to match our sealing bars. This is necessary for sealing applications featuring a spout, for instance. The heat-sealing band corresponds exactly to the contour of the closure. One particular challenge here is that instead of simply sealing the film, it must be sealed with a closure.
Customized version
Many applications require highly customized heat-sealing bands. We can provide exactly the right solution – from bands with multiple temperature zones to circular heating tools. With our longstanding experience and our 3D CAD system, even the most complex geometries are not a problem.
