Manufacture of plastic tubes MAINTOOLS GmbH & Co KG, which is engaged in the production of extrusion lines for the manufacture of plastic pipes, has achieved an important new development in its business field of corrugators. higher cooling water flow rates can be achieved. Besides that, also the curve-optimised circulation of the mould blocks as well as the quick-change system characterises the advantages of these corrugators. The replacement of a complete set of mould blocks takes less than 30 minutes.

KG is also engaged in the following business fields: winding pipe systems for large-scale plastic pipes, extrusion lines for the production of multi-layer composite pipes and extrusion lines for drip irrigation pipes. Maintools GmbH & Co KG – Germany

In addition to a compact design, the high performance corrugators Protos 165 and Protos 270 have a very high degree of flexibility. Equipped with a productive capacity of more than 30m per minute and an output rate of 800kg per hour, multilayer pipes with a maximum outer diameter of 165mm/270mm are produced, mainly for the fields of cable protection and sewage technology. The decisive factor for these extremely high production speeds is the direct, tubeless and completely wear-and maintenance-free cooling system. In combination with the further development of the mould blocks, 50%

Based on the newly developed drive concept, the Protos 165 does not need any manual or electrical adjustment of the mould block clearance. In addition to the minimisation of the maintenance costs due to the innovative cooling system, a significantly lower wear of machine parts can be reached by the weight advantage of the mould blocks as a result of the “Zooming Technology” of the Corrugator (ie the basic forms of the mould blocks “grow” or “shrink” together with the dimensions). In addition to the manufacture of corrugators Maintools GmbH & Co
