Product Description:

50-800mm Large Diameter HDPE Double Wall Corrugated Pipe Extrusion Machine Line


Application of the pipes produced:

electricity wire sleeve, urban water supply and drainage system, agricultural irrigation pipe, underground filtration irrigation and the water supply or drainage system in buildings, etc.


Characteristics of the pipes produced:

 Light weight, good performance of shock resistance, high rigidity, corrosion-resistance, cold and hot resistance


Characteristics of the machine:

Mould and Auxiliary Machine: The mould die is of high precision and the mould blocks are changeable. There are two cooling modes to the mould block, by water and by fan. The planetary cutting machine is of high cutting precision; SIMENS human-machine interface control system realizes high automation.

Extruder: The extruder can be designed according to the different materials; HDPE material uses high efficiency single screw extruder, the PVC material uses conical double-screw extruder.


  1. Two high efficient co-extrusion single screw extruders

2.It adopts excellent screw and new groove sleeve design,
which makes the extruder with bellow advantages: high plasticization rate,
smooth melt, stable production process, 
and enable the inside and outside layer of the pipe to use different materials
3. Corrugation forming block is made by special alloy material. It has high precision, 
intensity and outstanding heat emission.
4. Nitrogen treatment of the mould surface. There is wall thickness adjusting device
in the mouth mould and can produce pipes of different raw materials.
It has a flaring function, which can reduce the investment and enhance efficiency.
6. The production line adopts advanced Simens PLC control system
, with human-machine interface operating system, has high automaticity, easy operation.

Q:What is the principle of the 45 extruder machine?
The principle of the extruder is the theoretical process of heating, melting and mixing in the process of plastic conveying, including solid conveying principle, melt transportation principle, mixing principle, and solid bed crushing process, etc..
Q:How many roots are produced in an hour for an PVC tube extruder?
It depends on the type of your extruder and the specification of the tube you produced
Q:How to choose the mould of the cable extruder? Ten
Depending on your specific specifications, if XLPE is insulated, extrusion die with small touch line, set on the use of cable diameter, large core conductor than a few tenths of good, if you like to use 70 square tube extruding mold insulation of the conductor element some is big 1 can be set according to the touch, the tensile ratio calculation, PVC1.6 DYWL material with smaller good-looking it is simple of the extrusion process
Q:Why can the plastic extrusion machine extrude the flat bar?
What's the reason for pulling out the stripes?1, the vacuum is not enough.2, high temperature settings.3, formula lubrication is too much
Q:Extrusion blow molding machine, storage or continuous type good?
This is not good or bad, depends on what your product is If the product cycle large volume high capacity is bound to produce a product with storage because of your long,
Q:Extrusion machine operating procedures, specific points, thank you!
11 prohibit the use of hand to touch the dry test machine high-voltage appliances, electrical wiring or ground wire parts.No water on the 12 wire core.13, do not stop before the hand touch insulated wire core, wire connector and exposed parts; after high voltage breakdown, the wire core should first take discharge measures, and then repair.14 driving and parking should be directed by skilled workers to avoid misuse and risk.15, equipped with softening equipment, plastic machine, the operator can not arbitrarily move, adjust electrical and mechanical equipment; can not touch the wire, electric pulley, copper catheter parts.16 after the end of the drive, the power supply, water source and air source should be all closed, and the operation handle will be replaced in place, and the records of the shift shift will be kept in good order.
Q:Cable extruder how to match the mold, how to calculate the formula, ask the master pointing
Look at what you have in the form of mold, extrusion, drawing, or half pipe
Q:What are the two types of extrusion?
Extrusion? The extruder. The extruder is divided into single screw extruder and twin screw extruder, and the twin screw extruder is divided into two parts: flat, double and cone.
Q:What are the common extrusion molding products?
A plastic pipe, including water supply and drainage pipe, casing and other electrical B plastic doors and windows just C a variety of wire, cable, cable break, also includes a data line, wire headset D PVC ceiling e for plastic guardrail protection f roadside flowers and some decorative strips, temporary thought so much, there are a lot of specific products and you look at the things around you can think of
Q:What raw material does the extruder use?
An extruder in which an air vent is disposed at the center of an exhaust extruder to allow removal of air and volatiles from the processed plastic. The main machine of plastic extruder is plastic extruderIt consists of an extrusion system, a drive system and a heating and cooling system. 1. extrusion system extrusion system includes screw, cylinder extrusion die head, extrusion die head, molding parts of the extruder. Also known as extrusion die, extrusion die.
