Vacuum forming system in modern corrugators

The range of corrugators manufactured by Itib Machinery allows the production of corrugated pipes. These range from small pipes with internal diameters starting from 4.5 mm to big pipes with outer diameters of up to 1200 mm. At the K 2016 show, where it will be located at stand D37, in hall 15, Itib is drawing the attention of visitors to its corrugators for small pipes, showing a FMV15/70-110 model, along with a FV32/152. The first of these, thanks to a modular structure, which allows the chain length to be adjusted to the pipe length, avoiding scrap, and features a vacuum forming system and the possibility, locally, of changing speed and thus pipe thickness, is mostly intended for automotive applications. In fact, the trend in the automotive industry is to replace, whenever possible, metal pipe lines with corrugated pipes in thermoplastic materials boasting advanced mechanical and physical properties, composed of flexible corrugated sections, followed by smooth rigid ones.

The second corrugator with 152 pairs of moulds is the longest of the F32 range. It also has a vacuum forming system and a high efficiency cooling system, which makes it possible to reach very high speeds with HDPE and PP electrical conduits. Moreover, the vacuum forming system allows in-line insertion of electrical cables and XPE or XPE/Al/XPE tubes inside the corrugated pipe. These applications are increasingly common in countries with high labour costs. At K 2016 the staff of Itib Machinery will be happy to discuss, with visitors, other aspects of these corrugators and of the bigger ones that complete the range.
