Principle
Wood-plastic extruder is the core equipment of wood-plastic production line, which is used to melt, mix and continuously extrude wood powder and plastics (such as PE) into the required profiles. It is suitable for the manufacture of wood-plastic floors, wall panels, guardrails, decorative lines, door and window profiles, etc.
