In order to improve the variation in quality of tiny parts produced by micro Powder Injection Molding (μ-PIM) and to study the effects of compounding ratio and additives with a minute amount of materials, a new concept of small mixing and injection molding machine has been developed. This machine enabled to mix metal powder and binders followed by injection molding, therefore it can achieve to mold without pelletizing process, namely "pellet-less" injection molding. It has a small furnace to mix and plasticization when injection molding, plunger which works as a screw during mixmg and also plunger for injection molding. As a trial mixing and molding, it is confirmed that the pellet would be homogeneous in a certain mixing condition and the variation in density of micro dumbbell specimen was slight.
