China Pexa Oxygen Barrier Pipe Making Machine EVOH Oxygen Barrier Layer Coating Machine

3 Layer PEXa EVOH Oxygen Barrier Pipe Production Line
EVOH oxygen barrier Coating Layer Making Machine

PEXa/EVOH composite pipe is produced by two separate steps. first is singly layer PEXa pipe, produced by raw extruder; second is that outer EVOH oxygen barrier layer coating and adhesive layer, produced by co-extrusion die head with two extruders.
KAIDE is the leading supplier for EVOH oxygen barrier pipe machine suppliers in China, with advanced technology and plenty practical experience. The market share is more than 80%.

1) Advanced co-extrusion technology with two extruders and co-extrusion die head mold, which makes the composite pipe bond firmly with precise size.
The die head with vacuum function, sepcial for that outer layer coating layer making. Vacuum degree is controlled.
2) The screw and barrel are special designed according to the property of EVOH resin. It is suitable for stable extrusion of high melt pressure of oxygen barrier resin.
3) Two sets of heating oven are equipped for fast and sufficinent pre-heating of the pipe. Heating temperature is set and controlled by OMRON instruments.
3) SIEMENS PLC control system witn sync control function, easy to control that two hauling machines and two extruders.
4) Two laye anti-UV type pipes can be produce with the same line. One extruder can be little large to get more output, and production speed.
