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.
