Advantage of TONGSAN Brand double wall corrugated pipe machine:

1.       the main machine adopts special designed high efficiency screw which is specially used for polyolefin, it has the features of stable performance and high efficiency. the machine has two independent extruders, which can realize both inside and outside layer with different material and colors

2.      Composite extrusion die head with specially helical structure to make the wall thickness uniform and stable production.

3.      the forming machine has automatic power-off protection deivce. the forming machine can automatically exit from the die head to avoid equipment failure in case of electricity cut off suddenly. It also equipped with new type high transmitting ratio reducer, easy to operate and maintenance.

4.      the corrugated forming system is in combination with water cooling and air cooling to ensure high production speed continuously. Advanced programmable lubricating system minimizes the moulds wear so as to increase the life of service and ensure work smoothly with high precision to ensure the products quality stability.

5.      Mould adopts special aluminum alloy material and high precision die casting forming mould method, it has the advantages of high precision, high strength, good wearability and better heat dissipation performance.

6.      Wave structure launched a comprehensive new optimization design to reach the best combination of high-rigidity and low weight.

 

 

2.Consists of the HDPE double wall corrugated pipe extrusion machine

1. Extruder

High efficient single screw extruder for PE, conical twin screw extruder for PVC. the inner and outer layers of the corrugated pipe are independently feed material by two extruders. It can make the inner and outer layers produce different material and guarantee high efficiency extruding

2.Die Head

Materail: high quality alloy steel, nitrogen treatment

Equipped with stainless steel heater

 

the die head structure designed reasonably, running channel distribute uniformly, it could ensure extrusion steadily.

 

3.Mold and Forming machine

4.Haul off machine

5.Cutting Machine

6.Stacker
