Large parts

For large parts, the wall thickness to flow path ratio and the flow properties of the plastic are the decisive factors. In most cases, big parts can only be filled with more than one gating point. To avoid weld lines,
use is frequently made of sequentially controlled needle valve systems in these applications.
We offer the following solutions for large parts:

  • Hot runner systems with a high pressure resistance of up to  2200 bar
  • Needle valve systems with cascade control
  • Hot runner systems that are wired ready to install with screw-in nozzles
  • Wear-resistant nozzles for highly reinforced plastics
Our application technicians are available to ensure the perfect layout of your injection moulds.
