The lower range of water-cooled corrugators of ITIB Machinery is characterised by steel moulds.
They are in pairs and machined on five axis CNC machines to get extremely low tolerance and high-quality pipes.
They are hardened and running without any link inside hardened channels where cold water is flowing.
A rack is machined on the top and each mould is pushed by the main gear; each mould is pushing the next, forming and moving like a chain. All corrugators can be supplied with air or vacuum forming. In case of vacuum forming, channels are machined inside the mould and thin slots along the profile to suck the plastic material against the cold mould.
