The extruder adopts separate mixing screw design, which makes the plasticizing and mixing effect better. 

Equipped with the latest spiral distributor and reasonable flow channel design, in which the melt is evenly distributed and the temperature is constant, making the wall thickness of the extruded products more uniform and also ensuring that the thickness of the inner silicon core layer is suitable for the design requirements, which better controls the cost of the products.

Vacuum negative pressure closed loop control to ensure the constant vacuum degree of production.

Adopt synchronized servo speed control with wide speed range to ensure the synchronization of pipe extrusion speed and cutting trolley follow-up. 

For micro-silicon core pipe extrusion line, Liansu Machinery equips supporting high speed automatic winder, which can realize line speed of 60~100m/min.

With a maximum winding length of 1,000 meters for the 110 size, which reduces on-site connection of pipes and lowers the cost.
