During the process of understanding the application of powder metallurgy,we touched the metal injection molding technology,but we never knew before that it was completely different from the traditional metal forming technology,it has no any difficulties on the forming of the metal components with a pretty complex geometric shape,high mechanical and high precision requirement,thus promoting the breakthrough of powder metallurgy manufacturers industrialization.
When the powder metallurgy factory do the metal injection molding processing, except to prepare the needed metal powder, they has to add the binder, so wether it is metal powder or it is binder,both of them should meet the requirement,otherwise, it would impact the forming of metal parts.
Regarding the powder chosen,the MIM manufacturers have to use the round powder<=10um,and it must be very strict on the processing from mixing,injection,debinding to sintering,especially on the debinding and sintering process, because it would take a long time, so it causes a high production cost on powder metallurgy manufacturers.
In this case,powder metallurgy manufacturers researched a simple method, means flowing and pressure forming technology,it combined the superiorities of metal injection molding technology based on the metal powder pressing technology,and then add suitable coarse powder and fine powder,then add more plastic binder to improve the liquidity,filling and formability of mixed powder.
Thus currently this technology has been used by many powder metallurgy manufacturers to produce the high complexity accessories.
