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 scopeΦ 50 –Φ200mm,production speed is up to 0.6~1.5m/min
Optimum spiral copper sizing sleeve, its entrance carrying pre-cooling and powerful vacuum device to suit for high speed extruding pipe
Stainless steel cooling water trough is three-dimensional regulation, longitudinal move by motor. High efficient cooling comes from peculiar spraying nozzle and high efficiency water pump.
All kind polyolefine material, two layers or three layers spiral strengthening pipe can be co-extruded for various uses.
