Why is powder injection molding one of the most sought-after processes today? An important development direction of powder injection molding is closely related to microsystem technology. It is closely related to the microsystem technology. In the areas related to micro-systems, such as electronic information, micro-chemistry, medical equipment, etc., equipment continues to be miniaturized and its functions are becoming more complex. The powder injection molding technology provides the possibility of completion.
Micro injection molding technology is an improvement of traditional injection molding technology. It is a forming technology developed for parts as small as 1um. The basic technology is the same as traditional injection molding, but the particle size of the material powder is smaller. Using micro injection molding technology, we have developed a microfluidic device with a surface micro-layout precision of 10um, and stainless steel parts with a scale of 350um to 900um; completed the co-sintering or co-joining of different material components and composite layouts, and obtained magnetic/non-magnetic properties. Magnetic, conductor/non-conductor miniature composite parts.
Powder injection molding is one of the most sought-after processes today. Powder injection molding materials have been developed from the early iron-based, cemented carbide, ceramics, etc., which are not sensitive to impurity content and the function requirements are not very strict, to nickel-based superalloys, titanium alloys and niobium materials. The use of materials has also developed from layout materials to functional materials, such as heat sink materials, magnetic materials and shape memory alloys. The material layout has also developed from a single uniform layout to a composite layout. Metal injection molding technology can complete the molding of a variety of powders with different components, so a composite layout with a sandwich method can be obtained. For example, the composite of 316L stainless steel and 17-4PH alloy can complete the continuous adjustment of mechanical functions.
