When we talk about the possibility of manufacturing complex parts in MIM technology, these parts reflect what we mean perfectly. Knurling, text, thin walls and the extremely complex shape in terms of support for sintering, make these pieces a manufacturing challenge. The main difficulties found at the time of the development of the parts were the correct design of the geometry, especially to avoid deformations and cracks when we sintered the parts. It was necessary to redesign both hinges to avoid defects. The main advantages obtained doing these parts in MIM technology are the cost savings in manufacturing, which saves operations of machining and secondary welding and, therefore, we obtain parts with better final mechanical properties. The parts are hinges used in glass and wood doors and they can open doors up to 270o.
