Plastic Brush Filament Extrusion Line (Universal)
I. Product Description
The Plastic Brush Filament Extrusion Line (Universal) is a complete plastic extrusion system specifically designed for producing various general-purpose plastic brush filaments. This line melts and plasticizes plastic raw materials like PP, PE, PET, PA through precise molds and temperature control, then uniformly extrudes them through a multi-hole T-die, followed by cooling, drawing, winding, and other processes to produce plastic monofilaments with uniform diameter, moderate strength, and smooth surface, widely used in the manufacturing of various brush products such as industrial brushes, cleaning brushes, and daily-use brushes.
