Metal Injection Molding technology can be adopted to produce the parts with small and complex shape,it is a prominent advantage of Metal Injection Molding,so it is applied widely on various industry field.But for the relatively large-sized and thick wall metal parts,MIM can not be applied widely at present as the injection shaping and debinding difficulties,but we can improve and promote the mechanical property by enhancing the sintering technology,thus breaking the restriction of the size range of MIM technology,so the market competitiveness of MIM parts can be improved greatly.
Metal Injection Molding parts possess the advantages of good density,high surface smooth finish and good mechanical property,so its application range is be escalated,so the size of the parts is started to be changed from micro-size to large-size gradually.
The required average particle size of metal powder that be used on Metal Injection Molding process must less than 20um,and most of the wall thickness are under 10mm,while the size of the majority on the market is 20mm-30mm,so if the size restriction can be broke,the market value of Metal Injection Molding parts will be increased greatly.
In recent years,the domestic study on large-sized Metal Injection Molding parts is pretty hot,by the research,the difficulties on 2KG parts have been broke and the massive production has been realized,but the disadvantage is that the production is low relatively.We have learned,at present the weight of MIM parts has achieved 4KG,but as the reason of the weight, the debinding proces and the produce cost,the application is just on the Aviation industry and other special industry.
