The machine is composed of single screw extruder, die, cooling tank with sizer, hauler,cutting,winder. By adding braiden machine, it can be able to produce reinfoced hoses.
Q1：What are the production‑process differences between soft PVC hose and rigid PVC pipe?
A：Soft PVC hose extrusion line usually is equiped with single screw extruder,cooling tank ,and winder. But Rigid PVC hose extrusion line is equiped with conical twin screw extruder,calibration tank and stacker.
Q2：Why must a soft‑PVC hose extrusion line be equipped with a high‑speed mixing machine?
A：Soft‑PVC base material is rigid PVC powder. Various powder additives cannot be fully blended inside the extruder only. The high‑speed mixer mixes PVC resin, plasticizer, stabilizer and lubricant into a homogeneous compound.
