1. Far ahead in the industry! Innovative high-speed cooling solution of mould blocks brings higher output!

2. Unique in the industry! No platform which carry the mould blocks running and fixed central height of the bearer plate which carry mould blocks make the operation of production easier.

3. Unique in the industry! The left frame and the right frame which the mould blocks are mounted on can open and close freely. It makes the operation and maintenance easier.

4. Industry leading! Compatibility of mould blocks between different models of extrusion lines.

5. Industry leading! Innovative clasp style rapid assembly technology of mould blocks substantially shorten the time of changing the size of mould blocks.

 

 

THE EXTRUDER

 

 Efficient shield-style screw with a special blending-melt section greatly improves the plasticizing quality and output. and has a wide adaptability of raw material, especially suitable for the efficient extruding of PE/PP/PET/ABS. 

The advanced unsymmetrical notched design; an automatic water cooling system for temperature control is equipped on the feeding section, which duplicates the conveying efficiency. 

The extruder is equipped with sliding guide and a device for adjusting the central height. 

The vertical structure attached with a forced cycling oil cooling system cooled by cycling water. High torque and speed, and low noise; gear with rigid teeth by grinding treatment; heavy duty thrust bearing.

Driving and temperature control is achieved by PCC control system imported from B&R in Austria, which has been recognized and adopted by many international first-class extruding equipment manufacturers; and a 15″colour touch screen is equipped for easy operation and explicit display. 

 

Optional innovative MULTIEXTM multi-extruding and feeding system, by means of flexible combination of the extruding system, furtherly optimize the production solution for customized user, so as to realize a perfect matching between pipe sizes and extruder-combination. This solution brings a more flexible production style for you!

 

THE CORRUGATOR

 

500H Corrugator (making pipes of ID200-500mm)

 

Innovative mould blocks cooling solution of Model 500H corrugator from ZhongyunTech brings a fast and high efficient cooling of mould blocks, substantially increasing the production efficiency of PE double wall corrugated pipes.  
 

Innovative design of both the corrugator frame and mould blocks moving structure. When changing the size of mould blocks, you do not need to make any adjustment to the platform or frame of the corrugator any more, so that the work of changing pipe sizes become easier and faster!
 

The all-new design of corrugator structure makes the left frame and the right frame which the mould blocks are mounted on be able to open and close freely. 
 

The mould blocks on different models of extrusion lines can be interchanged completely through adopting a highly standardized system solution!

 

Innovative clasp style rapid assembly technology of mould blocks can realize easy and fast assembly of mould blocks on their bearer plates. This can greatly decrease the workload of changing mould block sizes and substantially increase the work efficiency!
 

 

Based on the further optimized design for the structure and running mechanism of mould blocks, it makes the mould blocks running forward and backward bidirectionally on the corrugator! It effectively overcome the structural defects that ordinary corrugator only allow the mould blocks run in one direction.

 

THE COOLING TANK

 

 The spray cooling flume side-opened on both sides makes the operation and maintenance easier. 

Stainless steel tank. 

An automatic control for water temperature and its level.

The guiding rollers are equipped in the flume, reducing the moving resistance of the pipe.

A powerful blowing dryer is equipped to get rid of the cooling water on the surface of pipes completely.

Equipped with a synchronously automatic pipe pulling device. 

 

 THE CUTTING MACHINE

 

 Planetary cutting style and hydraulic feed device with high precision can ensure flat and smooth cross-section of the pipes. 

The moving structure of cutter holder adopts a big gear transmission for high precision and long lifespan with easy and reliable operation. The vibration caused by the chain transmission can be effectively resolved. 

Equipped with an auxiliary inspection mechanism ensures the cutter accurately placing at the cut position.

Well-equipped with protection device ensures a safe operation. 

It is controled by PLC control system with normal communication interface for the convenience of connecting with compatible equipment.

 

 

THE UNLOADING DEVICE

 

Cut pipes can be smoothly conveyed to the stacking place by the initiative conveying device. The unloading device is well-equipped with perfect protection device to ensure a safe production. 
The central height of the unloading device can be easily and quickly adjusted by the electrical adjusting device when it needs to be adjusted because of changing pipe sizes. 

 

2.Product advantage:

Do you really know corrugated pipe production equipment?

Do you know there is difference in water cooling system for corrugators, 

which are Ordinary water cooling system and high-speed water cooling system individually?

 

 

In the field of PE/PP double wall corrugated pipe machinery,Zhongyun Group is the only enterprise in China that has manufactured all the three kinds of corrugators; As the leading manufacturer of plastic pipe machinery, Zhongyun Group has been guiding the direction of development forPE/PP double wall corrugated pipe machinery, represents the highest level of technology.
