Automotive lighting

Customer's Expectations
  • Validate the possibility to inject in a balanced way a full set of three different lightguides
  • High part quality with minimal variation in light temperature
  • Validate the possibility to inject very long and thin lightguide by using sequential injection


Our Solution

Oerlikon HRSflow supported preliminary tool design, with special attention to system layout and gate quality, testing different injection strategies by simulation in order to identify the best gating strategy and part layout with a constraint of very limited space. The final solution achieved considers optimized drop locations on cold runner and compact tool layout. Process settings have been also defined in order to ensure the best balancing on the part within a large molding window.

Oerlikon HRSflow system

The hot runner system layout adopted consists of 5 drops Ma series, FLEXflow system, single level with HP gate of Ø2.5 mm.
