The performance of metal injection molding process is comprehensive, including powder flow, stack density, vibration density, compressibility, formability, and sintering size change. For some special applications, powders with other chemical and physical properties are also required, such as catalytic performance, electrochemical activity, corrosion resistance, electromagnetic performance, and internal friction coefficient.
The performance of metal injection molding fully reflects the properties of the metal itself and the properties of individual particles and granules. Generally, the performance of metal powders is divided into chemical properties, physical properties, and process properties. Chemical properties refer to the metal content and impurity content.
Metal injection molding refers to a group of metal particles with a size of less than 1mm, including single metal powder, alloy powder, and some refractory compound powders with metallic properties. The production of metal injection molding mainly satisfies the requirements of injection molding for metal powder and binder. Then, the powder and binder are mixed uniformly into the feed using an appropriate method at a certain temperature. After granulation, they are injected molded.
Physical properties include the average particle size and particle size distribution of the powder, the true density of the powder, the shape, surface morphology, and internal microstructure of the particles. The basic properties can be determined by specific standard test methods.
