Tahun pembuatan: 2025, Kondisi: baru, Die DOLFİN-VDL Serie Trommel-(Spiral-)Teilereinigungsmaschinen werden insbesondere zur Reinigung von Kleinteilen eingesetzt, die in großen Mengen und massenweise gefertigt werden. Iedpjv S Dk Ssfx Al Tjba Die über den Einlaufbereich der Spiral-Trommel eingefüllten Werkstücke werden durch die Spiralen im Inneren der Trommel zum Auslaufbereich transportiert. Während sich die Trommel mit der eingestellten Drehzahl um ihre eigene Achse bewegt, werden die Teile – je nach Modell – in einem fortlaufenden Prozess den nachfolgenden Behandlungsstufen unterzogen: Waschen (Entfetten), Spülen, Passivieren und Trocknen. Da diese Prozesse sequentiell und kontinuierlich ablaufen, werden sie schnell und effizient in einer einzigen Maschine durchgeführt. Durch Drucksprühlen und Taucheffekte in jeder Sektion wird eine vollständige Durchdringung sichergestellt. Dieses Modell eignet sich besonders zum Waschen von Schrauben, Muttern, Unterlegscheiben sowie ähnlichen Kleinteilen, Fittings, Nippeln, Kupplungen und Verbindungselementen, die in CNC- und automatisierten Maschinen in hohen Stückzahlen bearbeitet werden. Unabhängig vom Metalltyp der zu waschenden Teile – Stahl, Messing, Aluminium, Kupfer oder Edelstahl – ist das System vollständig kompatibel. Da Dolfin-Teilereinigungsmaschinen im geschlossenen Kreislauf arbeiten, wird weder für jede Reinigungsvorgang neues Wasser noch neues Reinigungsmittel benötigt. Mehrere Waschgänge können mit demselben Tank durchgeführt werden; der gesamte Schmutz verbleibt dabei in der Waschtrommel. Dieses Merkmal schont sowohl die Umwelt als auch die Mitarbeitenden. Dank der hohen Effizienz und Leistungsfähigkeit werden Energie-, Wasser- und Arbeitskosten gespart. Das Gerät arbeitet kontinuierlich entsprechend der vor dem Betrieb am Bedienfeld eingegebenen Parameter. Massenhaft aus der Produktion kommende Teile können auf drei unterschiedliche Arten in das Gerät geladen werden: 1. Über eine vibrierende Ladekammer, 2. mittels eines Hebeförderers, 3. durch Anbindung an das vorhandene System des Kunden. Für weitere Informationen stehen wir Ihnen gerne zur Verfügung. Wir fertigen für Sie mit über 40 Jahren Erfahrung und exportieren mit Qualität und Vertrauen in über 30 Länder weltweit!
