VTC-200S is a benchtop vacuum melt spinning system for preparing amorphous metallic ribbons up to 2000ºC. In this technique, metal ingots are melted via the induction heating method and then propelled by over pressurizing the crucible. A thin stream of molten is then dropped onto a fast-spinning surface of a cold copper drum. This causes rapid quenching & solidification of the molten and thus form the ribbon (< 10 mm width) of the liquid metal alloy The system features an SS air-tight chamber with a front observation window. A turbo backed by a dual-stage oil pump is optional for achieving a high vacuum up to 10^-6 torr. 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. The user can also control the RPM of the drum, induction heating power, temperature, and pressure applied to the crucible.SPECIFICATIONS: Features The 15 KW ( 220VAC, Three phases) induction heating system for worldwide use.

(Click Pic2 below) Sample transforming from glovebox to melt-spinner chamber (Pic. 3 &4 is available upon request. Compliance CE Certified NRTL certification is available upon request at an extra cost Application Notes Material testing using melt-spinning is available, otherwise, we use NbFeB as the standard for testing before shipping Please be advised that not every material can be melt spun. In order to achieve melt-spinning successfully, the material melt must have a proper viscosity. It is the customer's responsibility to find the right composition, crucible size, and power supply Ferromagnetic metals are generally responsive to induction heating. For refractory materials, e.g. materials with high melting point (>1200ºC) or low permeability (μ/μ0
