Hartlöten mit Lotformteilen
Hartlotringe, Spiralen und weitere Formen.
Das Löten mit einem Ring oder einem Formteil gewährleistet eine genaue Kontrolle des Lotvolumens und verbessert den Lötprozess.
- Viele HVAC+R- und Automobilhersteller werden diese Formteile in Zukunft verstärkt einsetzen (anstelle der manuellen Zuführung), z. B. beim Flammlöten
- Formteile müssen eine große Vielfalt an Geometrien abdecken und stellen daher eine größere Herausforderung für Kund:innen und Hersteller:innen dar.
Um dieser Nachfrage gerecht zu werden, können wir mit unserer neuen Ringmaschine zahlreiche Ringtypen herstellen. Außerdem können wir so höhere Fertigungsgeschwindigkeiten und kürzere Lieferzeiten erreichen.
Fontargen Brazing bietet die folgenden Standard-Lotlegierungen an:
