VENUS MULTI, SUPREME TECHNOLOGY FOR MULTILAYER SOLUTIONS


Global market for complex plastic pipes with functional layers followed a technological evolution trend, with emerging of functionality and cost saving requirements. Set up on Venus concept, Venus Multi is the appropriate die-head system for the production of 2, 3 or 4 layers polyolefin pipes.

The key component in any multilayer pipe production line is the die head. Tecnomatic with Venus Multi has developed a system based on multiple spirals design to ensure the optimal melt flow for a wide range of thickness ratios. The die-heads are extremely compact with a low pressure build-up and consequent energy savings. Lower pressure also results in a lower increase of the melt temperature assuring improved pipe’s characteristics with regard to OIT (Oxidative Induction Time) values, extra weight and thermal and sheer stresses reduction.

The die-sets comprise of two parts with a small end ring to define the gap of the die, permitting a rapid size change and adjustment. A Pipe Air Cooling (PAC) system provides intensive cooling of the inner pipe surface by sucking air in the opposite direction to extrusion.

According to requirements, custom fit solution can be offered and engineered to maximize performance, cost saving, and space, without compromises on product quality.

Your benefits at a glance

 
  • The flows melting point is designed to adapt to a wide range of thickness-ratios.
  • Smooth flowing to keep the material properties unchanged.
  • Short die-set and segmented mandrels allow an easy and quick die-sets change, reducing the line downtime.
  • Even wall thickness distribution for lower overweight of pipe and raw material saving.
  • Pipe Air Cooling (PAC) system to short the cooling and to improve the pipe quality.
