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:Computer case shell plastic is injection molding or extrusion molding?
It must be injection, you see that hole, that button, can not squeeze out.
Q:Extrusion machine (ACS510 frequency converter + ordinary motor), low speed production current, how to solve?
Fan, water pump at low speed, torque is not enough, resulting in high current, if vector control can be ideal.
Q:PVC extrusion machine extrusion stone floor no pressure, what reason?
PvC stone floor extruder pressure is adjusted by the screw and die head
Q:What is the adjustment method of China's extrusion machine die?
(4) lamp alignment: suitable for polythene plastic wires and cables. Use light to illuminate the insulating layer and sheath, observe the upper, lower, left and right sides of the thickness, adjust the screw to the die until it is even, then screw the screws.
Q:Basic parameters of extruder screw
3, compression ratio epsilon, also known as the geometric compression ratio of screw, is the ratio of the volume of the first screw groove to the volume of the last screw groove at the homogenization section. It is determined by the physical compression ratio of plastics - that is, the density of the product and the density of the performance of the feed. The extruder is relatively compressed, the purpose is to make granular plastics fully plasticized and compacted. The selection of compression ratio should be different when different kinds of processing plastics are used. According to the compression ratio, the types of screw can be divided into three types: equidistant, unequal depth, equal depth, unequal distance, unequal depth, unequal distance. Among them, equidistant and unequal depth is the most common one. This kind of screw is easy to process, the contact area of plastic and cylinder is large, and the effect of heat transfer is good.
Q:Taper twin screw extrusion machining of plastic masterbatch? What ancillary equipment do you need?
because itself is not suitable for the design of double cone, adjustment of the formula is the key.
Q:What is the three layer coextrusion blow molding machine for blow molding of plastic bag tension formula,
Plastic tensile testing without tension is strong that said, you should be the low tensile strength, tensile strength for 2 kinds of films, one is the transverse tensile strength, a longitudinal tensile strength, is a reflection of the tensile properties, the tensile strength of the plastic bag if you low, because your choice of materials is not brittle material or toughness (PE/PP/PVC/PET/PBT/PC do not know or what material) if you insist on using this material, make plastic bags, you can modification method by crosslinking, adding additives, improving formula, to achieve the goal, the specific situation you need to find a degree in Polymer Science plastic engineer, they will tell you.
Q:Extruder price
According to the size of the screw, single and double screw configuration is different, there are many different prices between fifty thousand to two hundred thousand, we specialize in the production of extruders, crushers and mixing machines, high quality and low price, contact information on the user name
Q:Can PC and PP be extruded together with two materials in an extruder?
No co extrusion, PC polycarbonate, PP polypropylene, two kinds of product structure is not the same, not the same chemical composition, viscosity and liquidity is not the same, processing temperature and processing technology is also very different, and two kinds of products, so not incompatible, CO extrusion.
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
