Plastics and metal molding specialist Arburg says that it will exhibit a smartphone housing made using metal injection molding (MIM) at EuroPM, taking place in Milan this October.

 PIM process development manager Marko Maetzig will also be giving a talk on the production of MIM parts with a high aspect ratio for smartphone applications.

This extends the application range of metal injection molding, which up to now was more likely to be used to manufacture small and complex parts – an area in which Arburg is active and already enjoys an established reputation in various industrial sectors,’ said Maetzig. The main focus when it comes to the manufacture of PIM housings and frames for smartphone is achieving flawless surfaces and minimal part tolerances, the company said. However, the biggest challenges in the injection molding of thin-walled metal components are complete mold filling and minimising distortion during the subsequent sintering process.
