[16F-T12-10] Mix Solution Providing Excellent Fillability and High Apparent Density to Improve Compaction Performance
Keywords:Powder mix, Lubricant, Productivity
Cost-efficient manufacturing of high-performance components requires mix solutions with high apparent density (AD) and good fillability. This is especially critical for taller and more complex shaped components, where powder solutions with higher AD and consistent die filling are crucial. Traditionally, metal stearate lubricants have been used to obtain high AD. However, these lubricants not only provide high AD but also leave residues in the sintering furnace, requiring regular maintenance stops. Höganäs’ new bonded mix solution, Starmix Nova, is developed to offer high AD and excellent flow without using metal stearates.
This study is based on both laboratory experiments and compaction trials in production environment. Compared to a standard premix with amide wax, Starmix Nova mixes achieves 0.3 g/cm3 higher AD, equivalent to a premix containing Zn-stearate, while exhibiting faster flow and better lubrication. In production trials, Starmix Nova showed improved component weight consistency and productivity.
