Double Wall Plastic Pipe Extrusion Machine / Corrugated Pipe Extruder

• Compound material color mixer ( Optional)

PVC/PE/PP compound material color mixer machine is main used in PVC/PE/PP compound resin adding, drying, coloring and mixing with master batch according to different colors requires for making different colors of PVC/PE/PP Double Wall Corrugated Pipe function purpose.

PVC/PE/PP compound material color mixer machine is composed of silo,motor, gear reducer box, stir blade and control cabinet.

• Vacuum Loader Machine

Vacuum loader machine is used for loading soft PVC/PE/PP compound resin material into hopper on the top of extruder from ground. Soft PVC compound resin material will be transported by vacuum covery in the middle of soft PVC suction hose pipe automaticly. It is controlled by timer too. The working principle of this vacuum loader is negative pressure.

• Single Screw Extruder

Single screw extruder is main part of PVC/PE/PP Double Wall Corrugated Pipe making machine line. It is used for feeding,transporting, plasticing,melting soft PVC/PE/PP compound resin material.

Single screw extruder is composed of driven motor, gear reducer box, screw and barrel, casting aluminum heater, cooling blower, hopper and control cabinet.

Driven motor: It is main part of single screw extruder. We'd better choose good brand AC type driven motor matching with inverter controll for saving power running cost.

Gear recuder box: It is used for connecting motor and for reducing rotating speed of screw through size and teeth of gear changing in the gear box.

Screw and barrel: It is most important part of single screw extruder. Design of single screw is becoming to special and customzied now due to many different kind plasic materials are using. The surface of screw should be paint double alloy for anti-wear.

Casting aluminum heater: It is used for heating barrel and screw which ensure mixed PVC/PE/PP resin material can be plasticizing and melting under the suitable temperature.

Cooling blower : It is used for cooling barrel and screw. if temperature of screw and barrel will be excess setting temperature, cooling blowers start to work for cooling barrel which avoid PVC/PE/PP material resolved in the inside of barrel.

Hopper : It is used for keep the mixed PVC/PE/PP resin material in the silo and make sure material can be into barrel continuously. It is like a material transport station.

Control Cabinet: It is used for control whole cornic double screw extruder running by switchs or PLC programes according to different circuits control required.

• Extrusion Mould & Die Head

Extrusion mould and die haed is another important part of PVC/PE/PP Single Wall Corrugated Pipe production line. Soft PVC/PE/PP compound material will be forced into extrusion die and mixing steel wire together through connect flange by screw forward transported after plasticizing and melting in the inner side of barrel.

• Forming device

Forming device is used for forming pipe into corrugated shape .

• Coiler

Coiler is used for winding PVC/PE/PP Double Wall Corrugated Pipe automaticly. There are two type of coilers, one type is single disc coiler, anther one is two disc coiler. In normal, single disc coiler is enough for PVC/PE/PP Single Wall Corrugated Pipe only.
