Preformati per brasatura
Anelli pieni o animati, spirali, preformati o laminati per brasatura nudi o con anima di disossidante.
La brasatura con un anello o un preformato garantisce un controllo accurato della quantità del metallo d'apporto e migliora il processo di brasatura.
- Molti produttori nel segmento HVAC+R e Automotive utilizzeranno questa tecnologia in futuro (in alternativa dell'alimentazione manuale), ad esempio per la brasatura a fiamma.
- I preformati di brasatura devono coprire una grande varietà di forme e dimensioni quindi diventano meno versatili.
Per rispondere a questa domanda, le nostre nuove macchine per la produzione di anelli ci permettono di realizzare differenti sagome di anelli, garantendo una maggiore efficienza durante il processo di brasatura e giunti di brasati di migliore qualità. Inoltre, ci consente di raggiungere velocità di produzione più elevate e tempi di consegna più brevi.
Fontargen Brazing fornisce le seguenti leghe di brasatura standard:
