| Single screw extruders especially used for polyolefine material possess effective plasticizing effect and high extrusion speed.The special detachment type mixing screw and the standard designed die with spiral structure & reasonable channel are applicable to produce pipes with smooth inside and outside face. The helix apportionment style diffluence body and big flow space assure the melting material has enough stay time. Optimal low melting temperature result in little internal pipe stress, smooth inner and outer pipe surfaces.Unique sizing and cooling mode is capable of producing pipe scope 50-200 mm,production speed is up to 0.6~1.5 M/min |
