U-PVC foam spiral silencer production line

Used for building drainage pipes. The unique internal spiral structure allows water flow to fall along the threads, greatly reducing the noise caused by water flow falling; After foaming, the specific gravity of the pipe material is reduced to below 0.9, and the foaming is uniform, with high strength and low weight.

The host adopts two twin-screw extruders for co extrusion, and the advanced process formula has been developed through years of practice and experience. Special designed co extrusion die heads can be used to simultaneously produce solid wall tubes, solid wall inner spiral tubes, foam tubes, and foam inner spiral tubes by simply changing the core rod. By replacing the mold, we can produce nano antibacterial PVC water supply pipes and hollow wall spiral silencing pipes
