20-63mm PPR Pipe Extrusion Line

A pipe extrusion line consists of different parts. An extruder converts raw plastic material into a continuous tubular melt by extrusion through an annular die. The molten pipe then proceeds through a sizing or calibration bench (which adjust its dimensions) to a cooling tank.The major steps in plastic pipe extrusion involve the melting down of the resin beads, filtration of the melted resin beads to enhance uniformity. Also, the homogeneous melted resin beads are forced through a die-cut for the final product sizing and then cooled.Extrusion is a process where a material undergoes plastic deformation by the application of a force causing that material to flow through an orifice or die.
