PVC corrugated pipe machine
Conical twin screw extruder is featured with high efficient compounding, low rate of shear, difficulty to decompose material, high output, good self-cleaning function and long service life.  it is more suitable for PVC powder. The extruder has a vacuum degassing, a screw inside oil cooling, wind cooling or oil cooling of barrels. The horizon style forming machine’s work table can be adjusted in direction of transverse, vertical and horizontal. Forming blocks are made of special high quality alloy steel, and has many advantages like high strength, good abrasive resistance, low coefficient of thermal expansion. Because of wind cooling and water cooling mode, the forming machine is good for fast forming and good cooling effect.
