PIPE DIES | MACHINERY
Recent die developments include a multi- layer design to make PEX pipe, a crosshead for corrugated pipe and a die with ‘the largest adjustable melt gap ever produced’
Pushing the limits: update on pipe dies
Pipe dies are critical to the physical attributes of a product – whether it is a medical tube or a multi- layer pipe. In each case, careful die design ensures everything from correct dimensions to final product performance. Policonductos, an HDPE pipe extruder based in
San Luis Potosí in Mexico, has begun producing pipes up to 1,600mm in diameter using a new line from Battenfeld-Cincinnati. A key feature of the line is its pipe die, which comes with “the largest adjustable melt gap ever produced” – which the company says enables the production of pipes in a wide range of different diameters without conversion. “We are enthusiastic about the range of options
offered by this new line,” said Homero Garza, general manager at Policonductos. “We have been able to expand our product range to include large-diameter pipes and can now also produce pipe dimensions to individual customer specifica- tions without any problems.” The line also includes a SolEX 120 NG extruder, as well as all upstream and downstream compo- nents such as gravimetric metering, EAC internal

pipe cooling, vacuum tanks, spray cooling baths, haul-off and cutting saw. Policonductos reaches an output of up to 2 tonnes/hour on the line. It makes HDPE pipes with a colour stripe for fresh water supply, sewage disposal and mining applications, with dimensions ranging from 406 x 12.5mm to 1.651 x 97.1mm. The new line expands the range of Battenfeld-
Cincinnati’s fast dimension change (FDC) systems. Before, they could produce pipe in three size ranges, with the largest being 400-630mm. With the new pipe die, the first step has now been taken towards a completely new dimension for pipes up to 1,600 mm in diameter. For large pipes, such as those produced by
Policonductos, a die change would be necessary on a conventional line. The adjustable die saves cost and time – while also enhancing safety, says Battenfeld-Cincinnati.
