What Is a Corrugator Machine?
A corrugator machine is an extrusion machine that forms corrugated plastic pipe by shaping molten thermoplastic between counter-rotating mould blocks. It produces single wall or double wall corrugated pipe from materials such as PE, PP, PVC, PA and EVA.

How a corrugator machine works
Resin pellets are fed to an extruder, melted and forced through a die head; the corrugator’s mould chain forms the corrugation; the pipe is then cooled and hauled off. Changing the die and moulds varies profile and wall thickness on the same machine.
Single wall vs double wall corrugators
A single wall corrugator makes single-layer pipe (4.5 mm I.D.–65 mm O.D.) for conduit and harness tubing; a double wall corrugator makes twin-wall pipe (40–75 mm O.D.) with a smooth bore for drainage. See the full corrugator machine range for models and sizes.
Common applications
Corrugated pipe is used for electrical conduits, telecom ducts, medical tubing, automotive harness pipes, and sanitary / drainage pipes.
