Minimal Grammage (g/㎡)：3
○ Easy to clean, channels where the melted materials flow smoothly; no need to be disassembled for cleaning. The materials are easier to change.
○ Cantilever structure, easy experimental operation, easy experimental observation.
○ Thermal bonding device with a unique electrical heating system for more flexible and convenient temperature control.
○ Change from mono-component to bi-component : only necessary to add the extruder and spinning modules.
