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
