Production Of MIM Parts With A High Aspect Ratio

Metal injection moulding is an established production technology for the manufacture of small and complex shaped metallic parts for different industrial sectors. Over the last years there is a tendancy towards the production of larger parts with higher aspect ratios especially for the 3C market. The present paper is addressing the production of thin walled parts with a high aspect ratio for smartphone applications. The main focus is to achieve a faultless surface finish and narrow part tolerances.
