Product Description

Polyamide(PA nylon) Automobile Tube Production Line

This  pipe production line is used to produce 5 layer Polyamide PA oxygen barrier automobile fuel tubes. The inner and outer layer is PA 12 material, then two bonding layer, and middle EVOH oxygen barrier layer.
This multilayer PA fuel tubes are made by co-extrusion technology, with 5 sets of extruders. EVOH (Ethylene-Vinyl Alcohol) materials are widely used in automotive applications in multi-layer fule lines owing to their excellent barrier properties to aromatic and aliphatic hydrocarbons. These barrier materials are essential to limit environmental fuel emissions and comply with the challenging requirements of fast changing international regulations.




The PA multi-layer composite pipe can effectively reduce the automobile's emission pollution and meet higher environmental requirements. As the multi-layer composite pipe features an excellent resistance to penetration, it meets EU-III standards.

Multilayer Pipe Structure:
Inner layer:  PA 12
Inner adhesive layer
EVOH oxygen barrier layer
Outer adhesive layer
Outer layer: PA 12

MULTILAYER AUTOMOBILE FUEL PIPE MACHINE  

1)Extruder is special designed for PA raw material, so that extrusion output and plasticizing quality are effectively improved.

2)Multilayer co-extrusion die head adopts special moulds steel, matching up with the unique multi-layer co-extrusion technology and high accuracy CNC processing to create incomparable features of high reliability, usability and high precision.

3)Gravimetric material dosing system, thickness control system, and diameter measuring system are equipped to control produced pipe accuracy.

4)SIEMENS PLC system to realize many intelligent operations, such as multi-machine linkage, separate machine control, fault diagnosis, remote control etc. At same time, advanced on line monitoring and control technologies, such as servo tracking technology, static digital filter technology etc, are used to ensure plasticizing quality and produced pipe accuracy under high speed extrusion.
