Warm flow compaction based on warm compaction and metal injection molding is a new net-shape manufacturing technology which can produce complex powder metallurgy (PM) parts by conventional axial-pressing. Warm flow compaction makes use of improved flowability of powder binder mixture in an appropriate temperature to form complex PM-parts, like cross-shaped parts. The effect of the combination of coarse and fine powders on apparent density and flowability as well as the effect of different pressing speed and temperature on lateral flow capacity of iron-based powders were investigated. Results showed that apparent density increases as fine powder fractions increase, and transverse pressure becomes larger when pressing speeds are raised. The transverse pressure increases when the temperature of powder binder mixture approaches the melting point of the binder and the lubricant. The transverse pressure decreases as lateral-distance increases.
