 To date, twin roll melt spinning is still limited almost exclusively to laboratory scales.Auto Ejection Melt Spinning (AEMS) describes a type of melt spinning where ejection of the melt occurs as soon as it has liquefied, eliminating the need for a technician to manually control the flow rate, temperature, and/or release timing of the melt stream.This modification allows for a much higher ribbon consistency between runs, and a greater level of automation in the process.
