Tungsten Wire Production Process
- Rohmaterial: Wählen Sie hochreine Wolframpulver.
- Pulvermetallurgie: Mit Bindemittel mischen und zu einem grünen Knüppel verdichten.
- Sintern: Hochtemperatursintern, um das Bindemittel zu entfernen und die Dichte zu erhöhen.
- Zeichnung: Draw the tungsten rod through the dies to form fine wires.
- Wärmebehandlung: Glühen, um Spannungen abzubauen und die Eigenschaften zu verbessern.
- Oberflächenbehandlung: Reinigen und polieren Sie die Oberfläche.
- Schneiden & Anpassung: Zuschnitt oder individuelle Anpassung je nach Bedarf.
Tungsten Wire Processing Method
- Sintern
- Schmieden
- Rotationsschmieden
- Rollender
- Polieren
Tungsten Wire Surface Finish
Depending on the intended applications, tungsten wire has two main surface finishes as follows:
- Schwarz: Die Oberfläche ist “wie gesenkgeschmiedet” oder “wie gezogen”, wobei eine Schicht aus Bearbeitungsschmierstoffen und Oxiden zurückbleibt.
- Gereinigt: Die Oberfläche wird chemisch gereinigt, um alle Schmiermittel und Oxide zu entfernen.
