Plastic Paint Brush Filament Extrusion Production Line
I. Product Description
The plastic paint brush filament extrusion production line is a professional plastic extrusion system specially designed for producing high-quality plastic paint brush filaments (used for coating brushes, paint brushes, etc.). This production line uses precision molds and temperature control to melt and plasticize plastic raw materials such as PP, PE, PET, PA, etc., then uniformly extrudes them through a multi-hole T-die, and through processes such as cooling, drawing, and winding, produces high-strength, high-toughness, smooth-surfaced, solvent-resistant, and easy-to-clean plastic monofilaments, which are the core raw material production lines for professional brush manufacturing like paint brushes and coating brushes.
