Extrusion line for the production of single-wall and double wall corrugated tubes and pipes made of PE, PP, PVC, PA, EVA, PVDF, TPE etc.
Main applications:
Building industry: electrical conduit & sanitary hose duct/flexible pipe for siphon, PP-PE-PVC-PA
Automotive industry: Fuel line pipe & wiring harness tubing, PP-PA6-PA11-PA12-PA612
Medical industry: breathing tubes, LLDPE,EVA
Civil works industry: double wall cable conduit, HDPE
Agriculture: drainage pipe, HDPE, PVC
The range includes: Water cooling corrugator, Blow forming system corrugator, Vacuum forming system corrugator, Sequential mode corrugator, Variable Chain Length corrugator. corrugators systems for pipes with interior diameters from 4.5 mm and exterior diameter ranging up to OD700mm in a variety of thermoplastics. |
two types of pipe corrugator:
Internal blow moulding
Vacuum forming
Blow Moulding:
This technology consist of blowing low pressure (0,1-1,5 bar) through the die head spider into the center of the continuously extruded hot plastic tube. The air is retained by a plug with metallic or silicone washers.
The hot plastic material is expanded by the internal air pressure against the corrugation machined in the mould blocks which chill and holds the tube against the moulds to provide the desired geometry. Corrugated products formed by internal air must have constant I.D. dimension.
Vacuum forming:
This technology consists of pulling the hot plastic tube against the mould blocks by vacuum suction applied through the moulds applied to the plastic tube outside diameter surface. Vacuum from the moulds keep the tube against the moulds to provide the desired geometry. Corrugated products formed by vacuum may have variable I.D. dimensions.
