Electric spinning machine DX-II

high-speed

Overview
DX series Vacuum Melt Spinning System (DX-II) is laboratory equipment for preparing metastable and amorphous materials by ejecting molten metal/alloy onto a high-speed rotating copper roll under high vacuum, achieving extremely high cooling rates (10^4 K/s to 10^6 K/s) and enabling formation of amorphous/metastable phases.

Configuration of Vacuum Melt Spinning System:

• Stainless steel vacuum chamber
• Molecular pump (FF-200/1200) and mechanical pump (9L)
• Control cabinet with LED digital vacuum-meter
• Infrared thermometer and EV1000 frequency converter
• Melting-spinning oxygen-free copper wheel
• Blow-casting mold (including three mold cores, customizable)
• Magneto-fluid (water cooling)
• Spare parts (special tools and seal rings)
• Quartz tubes (50 pcs)
• Low-noise laboratory chiller

Note:
Users should prepare an Ar cylinder and a gas meter separately.
