It is a kind of composite material molding process, under the traction of traction equipment, the continuous reinforced fiber and its fabric products (reinforced fiber generally refers to glass fiber, carbon fiber, basalt fiber, etc.) are resin infiltrated. Extruded by forming mold, heating and curing, it can produce linear profiles of equal cross-section composite materials.
The pultrusion process is more suitable for mass production due to its production continuity.
