Atmosphere Controlled Melt Spinner With 150 mm Width Water Cold Copper Wheel and Precision Temperature Control System - EQ-VTC-500W

Please email for lead time
Item Number: EQ-VTC-500W
EQ-VTC-500W is an atmosphere controlled melt spinning system for preparing amorphous metallic ribbons. In this technique, metal ingots (<500g) are melted via induction heating method and then propelled by overpressurizing the crucible. A thin stream of molten is then dropped onto a fast moving surface of a cold copper drum. This causes rapid quenching & solidification of the molten and thus form the liquid metal alloy. 

The system features an SS air-tight chamber with a front observation window. A dual stage oil pump is included for achieving high vacuum upto 10^-2 torr. ISO 160 flange reserved for turbo pump connection if necessary. The unit provides inlet and outlet valves for inert gas purging. This helps to protect samples from moisture or oxygen exposure during the melt spinning process. User can also control the RPM of the drum, induction heating power, temperature and pressure applied to the crucible.


  • Complete system consists of the stainless steel vacuum chamber, turbo & mechanical pumps, 15KW induction heating system, rack system and one meter long discharging tubular collector.
  • 300mm diameter x 150mm Width copper flywheel with max. 50 meter /sec. spinning speed
  • Crucible to copper wheel distance adjustable (electrical adjustment via servo motor)
  • Large LCD touch screen control for temperature & induction power, copper drum spinning speed & ON/OFF, Mechanical & Turbo Pump ON/OFF, solenoid valves for pump isolation and gas purging, Melt-Spinning ON/OFF, and vacuum display.
  • Can melt metallic sample around 500g per batch.
  • TC insert to the bottom of the crucible can measure the temperature above the melt (direct contact between the TC and melt should be avoided)
  • Featured a position adjustable "scraper" can prevent ribbon spin-off to the inside of the chamber.
  • Featured a self-grinding/polishing mechanism for the copper wheel.  
Power Requirements
  • Input Voltage: 220VAC, Three-Phase, 60Hz
  • Input Power: 25 KW (A 70A breaker is required)
Vacuum Chamber &
Vacuum Pump
  • Vaccum chamber: 500×550×700mm (L×W×H)
  • Hinged type door with quartz observation window, illumination lighting provides better sight viewing of the process condition inside the chamber. Please see the picture below for details.
  • Built in mechanical pump with KF40 vacuum port (Can achieve 5 x10 E-2 torr within 30 minutes, 10E-3 torr limited)
  • Limited. vacuum level 10E-6 torr ( with turbo pump, which is not included )
  • ISO 160 vacuum flange is reserved for turbo pump connection. 

Induction Heater & Temp. Control
  • Dual Station 25KW Induction Heater 
  • BN Crucible: ( optional based on customer request )
  • Max. sample load: 150 - 500 g (depended on material). 
  • Melt temperature, dwell time and ejection time is controlled automatically by the controller
  • A precision temperature controller is integrated with B type TC (24'' long) insert inside the heating crucible. (direct contact between the TC and melt should be avoided)
  • 30 segments temperature profile programmable with +/- 2C accuracy
Control Station
  • All functional controls in one touch screen panel: Temperature & induction power control, copper drum spinning speed & ON/OFF, Mechanical Pump ON/OFF, solenoid valves for pump isolation and gas purging, Melt-Spinning ON/OFF, and digital vacuum display for Pirani gauge and Ionized gauge. 
Spinning wheel

  • Water cooled copper flywheel without water cooling ( 300 mm Dia. x 150 mm W )
  • 0 - 50 meter / second adjustable
Gas Pressure Regulator & Solenoid Valves
  • PID pressure regulator is included for precisely control the gas pressure applied to the crucible in order to propel the molten out from the nozzle. Please refer to the picture on the left to see the device.
  • Gas driven solenoid valves are used for isolating the pumps from the chamber when not used, chamber purging and pressure relief.
